Sextilis

Sextilis (Latin for "sixth") was the original name for the month that, after reforms, became the eighth in the year beginning with , aligning roughly with late to late in the modern reckoning. In the tradition attributed to King , Sextilis comprised 29 days, a length it maintained through the era until the reform of extended it to 31 days by redistributing intercalary time. The renamed the month in 8 BC to honor Emperor (formerly Octavian), citing key milestones in his life and rule that occurred therein, including his inauguration as , the dedication of the , the conquest of , and the conclusion of the civil wars—events later enumerated as justification for the change. This renaming paralleled the prior transformation of to in tribute to , reflecting the deification and commemoration of Rome's transformative leaders through the . Unlike popular accounts, the transition involved no further alteration to the month's length, which had already been standardized at 31 days under Caesar's solar alignment.

Etymology and Original Naming

Linguistic Origins

The name Sextilis derives from the Latin adjective , formed as a derivative of , the ordinal numeral meaning "sixth." This etymological root underscores its designation as the sixth month in the archaic calendar's sequence. The term sextus itself stems from the cardinal numeral sex ("six"), which is inherited from the séḱs, denoting the number six and appearing in cognates across , such as héx and ṣáṣ. In usage, months from onward followed this numerical pattern, with adjectival forms adapting to mensis ("month") as in mensis Sextilis. Linguistically, the suffix -ilis in Sextilis functions as a relational adjective-forming morpheme in Latin, common in calendar nomenclature to indicate ordinal position or association, paralleling forms like Quintilis from quintus ("fifth"). This convention persisted despite later calendar reforms shifting its absolute position, preserving the name's archaic numerical essence.

Position in Numerical Naming Convention

Sextilis occupied the sixth position in the original calendar's numerical naming sequence, which applied to the latter months of the ten-month year attributed to . This early calendar began with Martius in , followed by , , and Junius—months bearing non-numerical names linked to deities or seasonal activities—before transitioning to numerically designated months: (fifth), Sextilis (sixth), (seventh), (eighth), (ninth), and (tenth). The name Sextilis derives directly from the Latin ordinal sextus, signifying its ordinal placement as the sixth month, a convention that preserved the calendar's alignment with the agricultural and seasonal cycle starting from . This numerical scheme for the final six months contrasted with the initial four, highlighting a possible evolution from an even older Italic or lunar-based system where counting emphasized the core counting period after winter's unallocated days. The retention of these positions underscores the calendar's conservative adaptation, as later reforms by added Ianuaris and at the front, shifting Sextilis to the eighth slot without altering its name.

Development in the Roman Calendar

Romulus' Ten-Month Calendar

The calendar traditionally attributed to , the legendary founder of , featured ten months spanning 304 days, commencing in with Martius and omitting winter as an uncounted period before the year's renewal. This structure aligned with agricultural cycles, beginning near the vernal equinox, and drew from lunar observations while approximating solar seasons imperfectly. The months were Martius (31 days), (30), (31), Iunius (30), (31), Sextilis (30), September (30), October (31), November (30), and December (30), with four longer months interspersed to total the year's length. Sextilis occupied the sixth position in this sequence, its name deriving from the Latin sextus, signifying "sixth," consistent with the numerical designations for the latter months despite the calendar's limited count. Positioned after and before , it fell in late summer, encompassing harvest-related activities, though specific festivals tied to Sextilis in this era remain sparsely documented in surviving accounts. Ancient historians such as and reference this ten-month system as the initial Roman framework, reformed later by to address seasonal drift from the true solar year of approximately 365 days. The omission of winter days reflected a practical focus on active farming months, treating the dormant season as extracalendrical. This calendar's lunar-solar hybrid nature required periodic adjustments, but under , no intercalation mechanism is attested, leading to progressive misalignment over time. Sextilis, as the penultimate pair's opener in the numerical series, retained its 30-day length through early reforms, underscoring the system's emphasis on even divisions for administrative simplicity. While the attribution to is rooted in annalistic tradition rather than verifiable , it represents the foundational model from which subsequent s evolved, preserving numerical month names into the .

Numa Pompilius' Reforms

, the second reigning circa 715–673 BC, reformed the inherited from by expanding it from ten to twelve months through the addition of and , aiming to align it more closely with lunar cycles. This adjustment produced a year of 355 days, with months generally alternating between 29 and 30 days to approximate the lunar year's length, though the system required periodic intercalation to synchronize with the solar year of approximately 365 days. According to , Numa's division into twelve months reflected an effort to distribute the winter period previously unaccounted for in the original . Plutarch reports that Numa repositioned as the first month of the year—previously the eleventh under —and shifted Martius from first to third place, with inserted as the second or, in variant traditions, placed at the end before the intercalary period. This restructuring preserved the numerical designations of later months like and Sextilis relative to their positions counting from Martius, rendering the names anachronistic in the new sequence but maintaining continuity with prior . Sextilis thus remained the sixth month when enumerated from Martius, positioned after in the sequence Martius, , , Iunius, , Sextilis, despite the overall calendar now commencing in . To address the discrepancy between the 355-day and the solar year, Numa instituted an intercalary month known as (or intercalaris), inserted after every second year and consisting of 22 or 27 days, though its application was entrusted to the pontifices and often mismanaged in practice, leading to cumulative drift over time. Under this system, Sextilis retained a length of 29 days, consistent with the odd-numbered day assignments Numa favored to accord with cultural aversion to even numbers. These reforms, while improving the calendar's lunar fidelity, did not fully resolve solar alignment issues, which persisted until later adjustments.

Julian Calendar Standardization

In 46 BC, , advised by the Alexandrian astronomer Sosigenes, enacted a comprehensive reform of the to align it with the solar year, addressing the drift caused by irregular pontifical intercalations in the preceding lunisolar system. This involved inserting additional months into 46 BC—known as the "year of confusion" with 445 days—to realign the with the seasons, followed by the of fixed month lengths totaling 365 days in ordinary years. , previously a 29-day month under ' framework, was lengthened by two days to 31, contributing to the overall addition of 10 days to the annual total. The set Sextilis as the eighth month in a sequence where lengths alternated primarily between 30 and 31 days, though with exceptions including both the seventh () and eighth months at 31 days to approximate solar cycles more accurately. This fixed structure abolished adjustments, ensuring Sextilis' duration remained constant regardless of intercalary needs, which were now confined to a single leap day added to every fourth year (ante diem bis sextum Kalendas Martias repeated). The reform's precision stemmed from astronomical calculations, yielding an average year of 365.25 days, though it slightly overestimated the . Implementation began on 1 January 45 BC, marking the first full year under the new system, with Sextilis occurring from 25 to 24 in the modern proleptic reckoning. Ancient sources, such as Censorinus and , corroborate the month lengths post-reform, emphasizing role in establishing a predictable that facilitated administrative consistency across the . This standardization persisted until the later renaming of Sextilis to in 8 BC, without alteration to its length.

Renaming to August

Senate Decree of 8 BC

In 8 BC, the Roman Senate issued a senatus consultum formally renaming the month of Sextilis to Augustus (later Latinized as August) to commemorate the emperor Augustus' achievements. The decree highlighted Sextilis as the month in which Augustus had first entered the consulship in 43 BC, secured victory at the Battle of Actium in 31 BC ending the civil wars, incorporated Egypt as a Roman province in 30 BC, and celebrated a triple triumph in Rome. These events, as recorded in contemporary accounts, underscored the month's symbolic importance to Augustus' consolidation of power and the onset of the Pax Romana. The renaming paralleled the earlier senatorial honor of rechristening Quinctilis as Julius (July) after Julius Caesar in 44 BC, establishing a precedent for immortalizing leading figures through the calendar. Suetonius notes that Augustus specifically endorsed Sextilis over his birth month of September for this distinction, citing its alignment with his pivotal military and administrative milestones rather than personal chronology. This act of the Senate reflected the institution's role in augmenting imperial prestige during a period of relative stability following the Julian reforms, though it also bespoke the evolving concentration of authority under Augustus' principate. No adjustments to the month's length—fixed at 31 days since Julius Caesar's in 46 BC—accompanied the decree, preserving its structure amid the honorific change. The decision drew from a senatorial motion, as preserved in ' Saturnalia, emphasizing empirical ties to verifiable historical events over mere flattery. Subsequent emperors, such as , reportedly declined similar proposals to rename , indicating the exceptional nature of ' calendar perpetuation.

Ties to Augustus' Life and Achievements

The Roman Senate's decree of 8 BC renaming Sextilis to was explicitly linked to pivotal events in ' career that occurred during that month, underscoring his military triumphs, administrative ascent, and establishment of imperial peace. According to the late antique author , citing a , the month held special significance as the time when (then Octavian) was first elected on August 19, 43 BC, marking his entry into high republican office amid the turmoil following assassination. Further tying the month to Augustus' achievements, Cleopatra VII's suicide on August 10 or 12, 30 BC precipitated the annexation of as a , eliminating a key rival power and securing vast grain supplies and wealth for under Augustus' direct control. This conquest, following the in 31 BC, exemplified his strategic consolidation of Mediterranean dominance and economic stabilization. Complementing these, Augustus celebrated a triple triumph on August 13–15, 29 BC in , honoring victories in Illyricum, at against and , and the subjugation of —events that symbolized the end of and the advent of the pax Augusta. also associated the month with the closure of the Temple of Janus' doors, signifying peace after prolonged conflict, though the first such closure under Augustus occurred in January 29 BC; the temporal proximity reinforced the month's auspicious connotation. These milestones collectively highlighted Augustus' transformation from a youthful heir to the architect of Rome's imperial foundation, with the renaming serving as to eternalize his akin to Julius Caesar's prior honor for . The adjustment of August to 31 days, matching 's length, further emphasized parity in stature between uncle and nephew, reflecting Augustus' emphasis on restoring the while amassing unprecedented authority.

Calendar Structure and Dates

Length and Adjustments

In the ten-month calendar attributed to , Sextilis was the sixth month and consisted of 30 days, consistent with the even-numbered months in a scheme totaling 304 days for the year. Following ' addition of and around the , Sextilis shifted to the eighth position and was shortened to 29 days, aligning with the "hollow" designation for most even months in the reformed 355-day lunisolar system. The reform, implemented in 46 BC under , extended Sextilis to 31 days by incorporating two additional days, as part of redistributing 90 days across the year to achieve a 365-day alignment (with February at 28 days, or 29 in ). This adjustment positioned Sextilis among seven 31-day months (, , May, , Sextilis, , ), breaking the prior alternation pattern to balance the calendar. No further changes occurred upon its renaming to in 8 BC; the month already matched (later ) at 31 days, refuting later accounts—such as those by medieval scholar —that personally augmented it out of rivalry with . The 31-day length has endured in successor s, including the revision of 1582.

Roman Dating Conventions in the Month

In Sextilis, as in other Roman months not designated as "long" (March, May, July, and October), the Nones occurred on the fifth day, and the Ides on the thirteenth. The Kalends marked the first day, serving as the reference for the preceding month's final days but initiating the count for Sextilis itself. This tripartite division facilitated the inclusive backward reckoning of dates, a system rooted in lunar observations but standardized by the late Republic. Dates from the Kalends to the Nones were counted backward from the Nones inclusively. For instance, the fourth day was termed pridie Nonas Sextilis (the day before the Nones), while the third was ante diem III Nonas Sextilis (three days before the Nones, including the third, fourth, and fifth). The second day was ante diem IV Nonas Sextilis, and the first, though the Kalends, could also be expressed as ante diem V Nonas Sextilis in some contexts, though primarily Kalendis Sextilibus. Between the Nones and , reckoning proceeded similarly from the . The sixth day, immediately following the Nones, was ante diem VIII Idus Sextilis (counting inclusively: sixth through thirteenth). The twelfth was pridie Idus Sextilis, and the thirteenth simply Idibus Sextilibus. This yielded eight days in this interval, consistent with the five-day span to the Nones. Post-Ides dates were reckoned backward from the Kalends of the following month, . With Sextilis standardized to 31 days under the , the fourteenth was ante diem XIX Kalendas Septembris, progressing to the thirty-first as pridie Kalendas Septembris. Earlier, under Numa's , Sextilis had 29 days, shortening the post-Ides period accordingly, but the naming conventions remained unchanged. This emphasized relational over absolute numbering, aligning with cultural preferences for contextual reference over sequential enumeration.

Observances and Festivals

Pre-Imperial Religious Events

In the pre-imperial Roman calendar, Sextilis hosted several feriae stativae dedicated to agricultural prosperity, fire prevention, and the storage of harvests, reflecting the month's alignment with late summer activities in the Mediterranean climate. These festivals, rooted in archaic Italic traditions, predated the Julian reforms and emphasized communal sacrifices, libations, and games to ensure bountiful yields and avert natural hazards. Primary sources such as Ovid's Fasti and Varro's De Lingua Latina describe these observances as integral to Republican religious practice, with priesthoods like the flamines and Vestal Virgins performing rites at key shrines. The Vinalia Rustica, observed on 19 Sextilis, marked the grape harvest with libations of new wine poured to and, in later custom, Venus as patroness of vineyards. Magistrates and vintners participated in tastings and offerings at the or rural altars, symbolizing the transition from growth to vinification; this rite, attested in agricultural treatises, underscored wine's role in Roman diet and ritual purity. On 21 Sextilis, the honored , the deity of subterranean grain storage, with sacrifices of lambs and the unyoking of horses and mules—animals essential to plowing—followed by races in the . Tradition linked this to ' era, when it facilitated the Sabine women's abduction, blending with martial commemoration; the Quirinalis led ceremonies at Consus' altar beneath the Aventine, emphasizing stored foodstuffs' vulnerability to spoilage. The Volcanalia on 23 Sextilis propitiated , god of destructive fire, amid peak summer heat when urban conflagrations posed risks; participants ignited bonfires on hearths and cast live , , or small mammals into flames as substitutes for larger sacrifices, a practice Varro noted for channeling Vulcan's fury away from homes. This festival, tied to workers and camps, highlighted causal concerns over uncontrolled combustion in densely packed cities. Concluding the month's major rites, the Opiconsivia on 25 Sextilis invoked Ops Consiva, goddess of abundance and fertility, with the offering cakes on her near the Capitoline while bare-handed to symbolize earth's unmediated bounty. Linked to as a harvest-closing observance, it reinforced themes of and resource preservation, performed without iron tools to honor agrarian origins.

Imperial and Post-Renaming Associations

Following the Senate's decree in 8 BC renaming Sextilis to , the month acquired explicit ties to the emperor's personal and political milestones, most notably his triple triumph over , , and , held on 13–15 BC, which symbolized the consolidation of his power and the onset of the Augusta. This event, among others like multiple consular elections and victories occurring in the month, justified the honor as per contemporary accounts, transforming into a symbol of stability and success rather than mere agricultural rhythm. Imperial observances overlaid traditional festivals with dedications to ' cult, including vows for the emperor's safety integrated into harvest rites like the Rustica on 19 August and Consualia on 21 August, which marked the and ingathering under state-sanctioned leisure. The , instituted by in 18 BC as an extended rest period from roughly 1 onward to reward laborers post-harvest, persisted and aligned with the renamed month's theme, effectively sacralizing agricultural closure with imperial benevolence and preventing labor unrest through mandated holidays spanning key late-summer dates. Annually, the Ludi Martiales on 1 August featured circus games honoring Mars, the deity central to ' self-presentation as avenger (Ultor) of , with the in his forum reinforcing these proceedings through associated rituals and processions that evoked ongoing imperial legitimacy. Post-Augustan emperors maintained such ties, incorporating into broader imperial birthday or victory commemorations, though without formal new dedicated solely to the month, ensuring its festivals blended republican piety with dynastic propaganda.

Iconography and Cultural Representations

Personifications in Art

In late Roman art, particularly mosaic calendars from the 3rd and 4th centuries AD, the month of August—renamed from Sextilis in 8 BC—was personified as a human figure embodying the culmination of the harvest season, often depicted as a male laborer wielding a sickle or carrying sheaves of grain to symbolize agricultural productivity during the hottest, driest period of the Mediterranean summer. These representations drew on longstanding traditions of anthropomorphizing time and seasons, associating the month with prosperity and imperial favor, though direct ties to Augustus himself in monthly iconography remain interpretive rather than explicit in surviving artifacts. Pre-renaming depictions of Sextilis as a distinct personified entity are absent from known sources, likely due to the scarcity of early calendar art and the rapid adoption of the new nomenclature in visual culture. A prominent example is the 3rd-century AD mosaic from Hellín (Albacete province, Spain), now in the National Archaeological Museum of Madrid, where August appears in a detailed panel alongside September, personified through figures linked to zodiac signs (Leo for August) and seasonal labors, including harvest scenes with tools and deities overseeing abundance. Similarly, the Monnus Mosaic from Trier (Germany, ca. 235 AD) features August as a youthful male figure in sleeveless attire, positioned near zodiac elements and evoking the physical toil of reaping under the summer sun. In illuminated manuscripts, the Chronography of 354 AD—commissioned by the statesman Valerius Constantius and illustrated by the calligrapher Filocalus—presents as a personified , likely a standing figure with attributes, integrating pagan traditions into a late antique format amid Christianizing influences. These artworks prioritized empirical seasonal cycles over abstract (Sextilis meaning "sixth"), reflecting causal links between agrarian and calendrical , with no evidence of politically motivated distortions in the depictions themselves despite the month's imperial renaming. Variations across provinces highlight local adaptations, such as emphasized hunting motifs in some North African examples potentially alluding to Augustan virtues of vigor, but core consistently underscores fertility and labor.

Medieval and Later Depictions

In , particularly in illuminated manuscripts such as and psalters, the month formerly known as Sextilis—renamed in 8 BC—was depicted through the "Labors of the Months" tradition, emphasizing seasonal agricultural activities rather than anthropomorphic tied to the original name. August scenes commonly illustrated grain with flails to separate kernels from stalks, reaping , or harvesting crops, symbolizing the peak of summer productivity in agrarian societies. These representations, devoid of references to Sextilis, focused on rustic to align with the Christian liturgical and feudal rural life, appearing in works from the 13th to 15th centuries across . A notable example is the 14th-century by Maestro Venceslao in the Torre Aquila of Castello del Buonconsiglio, , , where portrays two figures on a wooden platform amid a landscape of sheaves and tools, underscoring manual labor under sunny skies. Similarly, later medieval cycles associated the month with the zodiac signs (ending ) or (beginning ), occasionally integrating as a maiden figure holding , though this zodiacal element served astrological rather than etymological purposes. In the and early modern periods, depictions shifted toward antiquarian interest in , with scholarly illustrations reconstructing the occasionally labeling the month as Sextilis in historical or emblematic prints, but without widespread artistic personification. These appeared in works like almanacs or treatises on chronology, prioritizing textual accuracy over visual symbolism, as the reform's legacy rendered the old name obsolete in everyday . By the , August personifications in secular art, such as in tapestries or engravings, retained harvest motifs but increasingly incorporated imperial references to Caesar, blending heritage with contemporary .

Legacy and Historical Significance

Influence on Successor Calendars

The , introduced by in 45 BC, directly incorporated the pre-existing Roman month of Sextilis as its eighth month, assigning it a fixed length of 31 days to achieve a solar year of 365 days plus a leap day every fourth year. This reform eliminated the variable intercalations of the earlier Roman system while preserving the sequence and nomenclature of the months, with Sextilis retaining its position between (later ) and . The resulting Julian structure spread with Roman expansion, standardizing August's 31-day format across provinces and influencing administrative and religious dating in the empire. In 8 BC, the enacted the renaming of Sextilis to via the Lex Pacuvia de mense Augusto, honoring Emperor without altering its length or position; this change integrated seamlessly into the ongoing . Subsequent emperors, such as , briefly attempted further personal renamings but failed to supplant the Augustan name, which endured due to its alignment with imperial stability and the calendar's established use. The Julian month's naming thus set a precedent for eponymous honors, though no later rulers successfully replicated it on a lasting scale. The , promulgated by in , maintained the Julian months' names, lengths, and order—including August's 31 days—while refining the rule to omit three leap days every 400 years, addressing the Julian drift of approximately one day per century relative to the . Adoption proceeded gradually: Catholic states like and in , in (effective 1564 preparation), Britain and colonies in 1752, and Russia in 1918, with churches retaining Julian dates for fixed feasts but aligning civil use variably. This continuity ensured August's structure became the global standard via and international agreements, such as the 19th-century railway and postal synchronization. In , derivatives like agosto (, , ) and août () reflect the Latin Augustus, perpetuating the Roman imperial nomenclature in successor systems.

Enduring Numerical Anomaly and Reforms

The original Roman calendar, attributed to Romulus around the 8th century BC, consisted of ten months beginning with Martius (March), positioning Sextilis—derived from sextus, meaning "sixth"—as the sixth month in sequence. This structure aligned numerical prefixes with ordinal positions for months from Quintilis (fifth) through December (tenth). King Numa Pompilius reformed the calendar circa 713 BC by inserting Ianuaris (January) and Februarius (February) to approximate a lunar year of 355 days, initially placing them at the year's end before shifting to the beginning by around 452 BC. This adjustment displaced Sextilis to the eighth position without altering its name, creating a persistent mismatch where the etymology no longer reflected its ordinal placement—a numerical anomaly shared with subsequent months (September as ninth, etc.). Numa's changes prioritized cyclical alignment over renaming, establishing the irregularity that endured due to cultural and administrative inertia. The Julian calendar reform of 45 BC, enacted by with Egyptian astronomer Sosigenes, standardized the solar year at 365.25 days via and adjusted month lengths—assigning Sextilis 31 days to match (renamed Iulius posthumously in )—but preserved the original and numerical without rectification. In 8 BC, the Senate's Lex Pacuvia de Mense Augusto renamed Sextilis to Augustus in honor of Emperor , yet retained its eighth position and 31-day length, leaving the semantic disconnect intact as the prefix sex- evoked its pre-reform status. This anomaly persisted into the of 1582, promulgated by , which refined rules to correct drift (eliminating ten days and adjusting centurial years) but made no alterations to month ordering or names, prioritizing astronomical precision over etymological consistency. Subsequent calendar adoptions worldwide, including in the (1793–1805) and modern civil systems, inherited the framework without addressing the offset, rendering the eighth month's nomenclature a vestige of archaic design amid successive rationalizations for seasonal and solar fidelity.
