Robert Plot

Robert Plot (13 December 1640 – 30 April 1696) was an English naturalist, antiquarian, and academic who served as the first professor of chemistry at the University of Oxford and the inaugural keeper of the Ashmolean Museum.^[1]^[2] Best known for pioneering the genre of county natural histories in Britain, Plot documented fossils, minerals, plants, antiquities, and local customs in meticulous detail, earning him recognition as the "genial father of county natural histories."^[1]^[3] Born in Borden, Kent, to a genteel family, Plot was educated at Magdalen Hall (now Hertford College) in Oxford, where he earned a Bachelor of Arts in 1661, a Master of Arts in 1664, and a Bachelor of Civil Law in 1671.^[1]^[2] After teaching at Oxford, he pursued fieldwork in natural history, becoming a fellow of the Royal Society following the publication of his seminal work, The Natural History of Oxford-shire in 1677.^[1] In this illustrated volume, Plot described and depicted a large fossilized femur from a quarry in Cornwell, Oxfordshire—provided by Sir Thomas Pennystone—which is now recognized as the first published account of a dinosaur bone (likely from Megalosaurus), though he erroneously attributed it to a giant human or possibly a Roman war elephant.^[1]^[2] In 1683, Plot was appointed to dual roles at Oxford: the university's first Savilian Professor of Chemistry and the first keeper of the newly established Ashmolean Museum, where he curated collections of natural specimens gathered during his travels.^[1]^[2] He retired from these positions after seven years but continued his scholarly pursuits, publishing The Natural History of Stafford-shire in 1686, which similarly cataloged the region's geology, botany, zoology, and historical artifacts, including early maps and engravings.^[1] Plot's approach emphasized empirical observation and local specificity, influencing subsequent naturalists and contributing to the Royal Society's tradition of scientific inquiry since its founding in the 1660s.^[1]^[3] He died in Borden, Kent, at age 55, leaving a legacy as a foundational figure in English natural history and paleontology.^[1]

Early life and education

Family background and early schooling

Robert Plot was born on 13 December 1640 at the family estate of Sutton Barne in Borden, Kent, England, into a gentry family with ties to local landowners.^[4] He was baptized the same day in the parish church of Saints Peter and Paul in Borden.^[5] Plot was the only son of Robert Plot the elder, a landowner who died in 1669 at age 63, and Rebecca, daughter of Thomas Patenden of Borden.^[3] His family background provided a stable environment within the Kentish gentry, fostering early exposure to the region's rural landscapes and resources.^[1] Plot received his initial formal education at the Wye Free School in Kent, an institution known for instruction in classics and basic sciences during the mid-17th century.^[4]^[6] There, he built foundational knowledge that later aligned with his pursuits in natural history, influenced by Kent's diverse geology and flora, though his systematic interests emerged more fully during higher studies.^[7] This early schooling laid the groundwork for Plot's transition to university-level education at Oxford in 1658.^[4]

Oxford studies

Robert Plot matriculated at Magdalen Hall, Oxford (now part of Hertford College), in 1658, beginning his university education amid the intellectual ferment of the Restoration era.^[8]^[9] He progressed steadily through his studies, earning a Bachelor of Arts degree in 1661 and a Master of Arts in 1664 from Magdalen Hall.^[8]^[4] Following his MA, Plot remained at Oxford, taking on early academic responsibilities at Magdalen Hall, where he served as a tutor, dean, and vice-principal.^[8]^[9] In these roles, he contributed to the institution's governance and instruction, fostering his growing interest in natural philosophy while preparing for advanced legal studies. By 1671, he had transferred to University College, Oxford, where he obtained his Bachelor of Civil Law (BCL) and Doctor of Civil Law (DCL) degrees, both awarded cum laude, marking the culmination of his formal education in both arts and law.^[8]^[4] Plot's time at Oxford positioned him within a vibrant community of scholars, including figures like Robert Boyle and Thomas Willis, whose empirical approaches to natural history began to influence his own pursuits.^[9] This period laid the groundwork for his later antiquarian and scientific endeavors, emphasizing observation and collection as key methods in understanding the natural world.

Academic appointments

Professor of chemistry at Oxford

In 1683, Robert Plot was appointed as the first Professor of Chemistry at the University of Oxford, a position established through the endowment of Elias Ashmole, who funded both the professorship and the adjacent Ashmolean Museum.^[4] This marked a significant milestone in recognizing chemistry as a distinct academic pursuit at the university, building on Plot's earlier studies at Oxford and his travels in Europe where he gained practical knowledge in natural philosophy and experimental methods.^[1] Plot held the chair from 1683 until his resignation in 1690,^[10] during which time he delivered the inaugural chemical lectures and oversaw the equipping of a dedicated laboratory in the museum's vaults for practical instruction.^[11]^[12] Plot's teaching emphasized chemical principles with a focus on iatrochemistry, the application of chemistry to medicine, integrating theoretical lectures with hands-on demonstrations of processes such as distillation to prepare medicinal substances.^[11] He conducted these sessions in the new laboratory, where students could observe and participate in experiments involving the rectification of spirits and the extraction of active principles from natural materials, reflecting his belief in chemistry's practical utility for healing.^[11] Around 1677, prior to his appointment, Plot had already formed partnerships to produce and sell chemical medicines, underscoring his commitment to iatrochemical applications that informed his pedagogical approach.^[11] In his research, Plot investigated solvents known as menstrua, particularly the concept of the alcahest or universal solvent, which he described as a liquor capable of inseparably altering the constitution of dissolved substances into new forms.^[11] His manuscripts detail distillation techniques for achieving highly rectified spirit of wine, aiming to enhance its subtlety for alchemical and medicinal uses, including extractions from sources like the works of Basil Valentine and Flamel.^[11] These pursuits extended to broader alchemical applications in preparing remedies, though Plot maintained discretion about such interests in his public lectures.^[11] Plot's tenure advanced chemistry's institutional standing at Oxford by advocating for dedicated facilities and studies; he petitioned the king for a college to promote alchemical research, emphasizing its separation from traditional philosophical curricula to foster experimental innovation.^[11] This effort, detailed in his writings and printed in historical accounts, helped lay groundwork for chemistry's integration into university education, influencing subsequent developments in the discipline.^[11]

Keeper of the Ashmolean Museum

Robert Plot was appointed the first Keeper of the Ashmolean Museum in Oxford in March 1683, a position that overlapped with his concurrent appointment as the university's inaugural Professor of Chemistry.^[4] The museum, established through the donation of Elias Ashmole's extensive cabinet of curiosities, officially opened to the public on 24 May 1683, becoming the world's first university museum dedicated to public access and scientific display.^[13] Plot's role was pivotal in transforming Ashmole's private collection into a structured institutional resource for scholarly and educational purposes. As Keeper, Plot oversaw the cataloging, arrangement, and preservation of Ashmole's donations, which encompassed a diverse array of natural specimens such as fossils, shells, and botanical items; antiquities including historical artifacts; numismatic collections of coins and medals; and ethnographic objects from Asia, Africa, and the Americas.^[14] He organized the exhibits into thematic sections, including dedicated rooms for natural history, human artifacts, and coins, to facilitate systematic study and visitor navigation.^[15] Plot meticulously prepared manuscript catalogues of the holdings, achieving high curatorial standards that emphasized accurate documentation and protection of the specimens.^[16] Additionally, he managed ongoing acquisitions, such as fossils and coins, to expand the collection while integrating his chemical expertise to analyze and classify natural materials. Plot introduced several innovations in museum operations to promote public education and sustainability. He regulated visitor access by admitting groups in controlled sessions with doors secured during tours, ensuring the collections' security while broadening outreach.^[16] To support maintenance, he enforced entry fees collected by the Keeper, and he developed early visitor guides through his catalogues, which served as descriptive aids. Plot also delivered lectures on chemistry and natural history within the museum premises several times a week, fostering an educational environment that linked curatorial display with active learning.^[15] These efforts, approved by Ashmole in 1686, emphasized the museum's role as a center for scientific inquiry and public enlightenment. Despite these advancements, Plot encountered significant challenges, including ongoing administrative disputes with university authorities over governance and control of the institution, compounded by an inadequate salary that strained his financial position.^[4] These tensions culminated in his resignation from both the Keepership and the chemistry professorship in 1690.^[16] Plot's tenure laid foundational protocols for modern museology, particularly in cataloging systems, thematic organization, and regulated public engagement, which influenced subsequent scientific institutions across Europe by prioritizing preservation, education, and accessibility.^[15]

Scientific and antiquarian contributions

Natural history publications

Robert Plot's most influential natural history works were regional surveys that aimed to catalog the natural and artificial features of English counties in a systematic manner, drawing on empirical observation and collaboration with local informants. His first major publication, The Natural History of Oxfordshire (1677), was undertaken at the encouragement of the Royal Society and structured as an essay toward a broader natural history of England.^[17] The book provided a comprehensive survey of Oxfordshire's geology, including soils and strata; minerals and fossils, such as belemnites and the femur of what Plot described as a giant human thigh bone (later recognized as Megalosaurus); botany, including descriptions of numerous plant species; zoology, covering local mammals, birds, fish, and insects; and even antiquities like coins and inscriptions.^[18]^[19] This work featured detailed engravings, many by Michael Burghers, to illustrate specimens and landscapes, marking one of the earliest uses of such visual aids in English natural history.^[4] Building on this success, Plot published The Natural History of Staffordshire in 1686, adopting a similar organizational framework divided into sections on earths, stones, fossils, plants, animals, and human artifacts.^[3] The volume emphasized economic aspects of the region's geology, such as coal seams, iron ores, and clay deposits used in pottery, alongside descriptions of local industries like mining and salt production.^[20] It included maps of the county and 37 engravings, primarily by Burghers, depicting curiosities like echo phenomena and unusual rock formations.^[3] Plot's surveys relied on fieldwork, including measurements of natural features, and networks of correspondents who supplied specimens and eyewitness accounts from gentry, artisans, and physicians.^[21] In 1685, Plot issued De origine fontium, a philosophical treatise exploring the origins of springs and rivers through observational evidence and classical influences.^[22] He proposed that springs arose from seawater infiltrating subterranean channels, heated and propelled upward by underground forces, rejecting purely meteoric explanations like rainfall infiltration and citing biblical references such as Ecclesiastes 1:7 to support a circulatory system of waters.^[22] This shorter work, later excerpted in the Staffordshire volume, demonstrated Plot's method of integrating field measurements—such as river flows during dry periods—with theoretical reasoning drawn from Aristotelian meteorology.^[23] Plot's approach across these publications emphasized empirical methodology, including personal surveys, printed questionnaires distributed to locals, and the collection of physical specimens for verification, often facilitated by his Royal Society connections.^[21] He planned additional volumes, such as natural histories of Middlesex and Kent, conducting a 1693 field trip to Kent with Thomas Browne to observe chalk pits and ancient roads, but these remained unfinished, with partial manuscripts surviving in the Ashmolean Museum and Bodleian Library collections.^[21]^[9]

Chemical and antiquarian pursuits

Robert Plot engaged in experimental chymistry that blended traditional alchemical techniques with emerging scientific methods, drawing heavily on medieval sources such as the Lullian corpus and the works of Joan Baptista van Helmont. His pursuits included the preparation of Paracelsian chemical medicines and the distillation of substances like wine spirits in search of a universal solvent, a key alchemical goal believed capable of dissolving all materials. Plot also explored chrysopoeia, the transmutation of base metals into gold, incorporating procedures aimed at producing philosophical mercury—a volatile, transformative agent central to alchemical elixirs—and reported on related trials through his curatorial role at the Royal Society. These experiments extended beyond his academic duties, often conducted privately to balance secrecy with empirical observation, and contributed to his collection of metallurgical specimens for the Ashmolean Museum. Plot was elected a Fellow of the Royal Society on 6 December 1677, recognizing his early contributions to natural philosophy. He served as secretary from 1682 to 1684, during which he acted as joint editor of Philosophical Transactions, curating submissions on chemical phenomena, including alchemical processes and natural history observations relevant to chymistry. In this capacity, he facilitated the publication of reports on transmutation experiments and elixir preparations, promoting rigorous documentation while distancing the Society from overt speculation. His editorial influence helped integrate chemical inquiries into the broader Baconian framework of the Royal Society, emphasizing verifiable trials over mystical claims.^[24]^[23] In his antiquarian research, Plot systematically studied historical artifacts, focusing on Roman coins, inscriptions, and earthworks across Oxfordshire and Staffordshire. He cataloged Roman numismatics, examining their materials, inscriptions, and distribution to trace ancient trade and settlement patterns, often integrating metallurgical analysis from his chymical expertise. Plot investigated prehistoric and Roman earthworks, including barrows and monumental structures, interpreting them as evidence of early engineering and cultural practices; for instance, he documented burial mounds in Staffordshire as potential sites of ancient rituals. These studies bridged archaeology and natural history, treating artifacts as specimens for empirical study.^[3] Plot maintained extensive correspondence with antiquaries like John Aubrey, exchanging insights on folklore, ancient customs, and supernatural traditions preserved in local lore. Their letters discussed oral histories of pagan rituals and medieval superstitions, which Plot viewed as vestiges of pre-Christian practices worth documenting alongside physical remains. Additionally, Plot contributed to heraldic studies, compiling genealogical records and armorial bearings that informed his broader antiquarian framework, emphasizing the continuity of English heritage from Roman times.^[9]^[25]

Later life and legacy

Administrative roles and personal life

In 1690, following his resignation from his academic positions at Oxford, Robert Plot married Rebecca Burman (née Sherwood), a widow and daughter of Ralph Sherwood, on 21 August at Canterbury. The couple settled at Plot's family estate, Sutton Barne, in Borden, Kent, where they raised two sons, Robert (who died in March 1751) and Ralph Sherwood Plot, along with a daughter Rebecca who predeceased her father.^[26] Plot's administrative career expanded beyond academia in the late 1680s. On 3 October 1687, Archbishop of Canterbury William Sancroft appointed him a notary public, enabling him to authenticate documents in ecclesiastical contexts.^[27] That same year, the seventh Duke of Norfolk named him registrar of the Norfolk Court of Chivalry, a role involving the adjudication of heraldic disputes and genealogical inquiries. In 1688, he was further appointed Historiographer Royal for the Earl Marshal, overseeing records of nobility and arms. By early 1695, Plot received additional honors in heraldry. On 5 February, he was created Mowbray Herald Extraordinary at the College of Arms, a newly revived office that tasked him with genealogical research and ceremonial duties. Two days later, on 7 February, he was appointed registrar of the College of Heralds, managing its administrative and archival functions. These roles aligned with his antiquarian interests and provided income after his Oxford departure. After retiring to Sutton Barne around 1690, Plot focused on personal scholarly pursuits while managing the estate's finances and improvements, including enhancements to the property circa 1695. In his later years, he faced health challenges, beginning in the summer of 1695 with urinary calculi that severely impaired his mobility.^[4] Despite this, he undertook a brief antiquarian tour through Norfolk in September 1695, accompanying the Duke of Norfolk to gather heraldic and historical data in line with his new roles.^[27]

Death and posthumous influence

Robert Plot died on 30 April 1696 at the age of 55 in Borden, Kent, succumbing to urinary calculi after suffering from the condition for approximately one year.^[28]^[15] He was buried in the churchyard of St. Mildred's Church in Borden.^[29] In his will, dated 9 September 1694 with a codicil added on 26 March 1696, Plot provided for his wife Rebecca, granting her rings, jewels, household goods for life, an annual rent charge of £30, and guardianship of their children.^[30] His son Robert inherited the family estate at Sutton Manor, including woodlands and marsh lands, while tithes from Iwade Rectory were allocated to an unborn child (later named Ralph Sherwood Plot).^[30] If his direct descendants died without issue, the estate would pass to his niece Rebecca Taylor and her son Thomas, and Plot directed that tithes be used to endow a "Plotts Professor of Natural History" at the University of Oxford.^[30] Plot also left several unfinished manuscripts, including planned natural histories of Kent and Middlesex, which were preserved and later housed in Oxford collections, contributing to ongoing antiquarian and scientific studies.^[28] Plot's posthumous influence is most evident in the fields of geology and paleontology, where he is regarded as a foundational figure in English natural history through his empirical surveys of regional landscapes and fossils.^[4] His 1677 illustration in The Natural History of Oxfordshire of a large thigh bone from Cornwell, Oxfordshire—initially attributed to a Roman elephant, giant human, or unknown quadruped—holds the distinction of being the first published depiction of a dinosaur bone, specifically from Megalosaurus.^[4] This image was rediscovered and reinterpreted in the early 19th century by geologist William Buckland, who in 1824 formally described Megalosaurus as an extinct giant reptile based on similar fossils from the same Jurassic strata, marking a pivotal moment in recognizing prehistoric life forms. In modern scholarship, Plot's legacy endures through his pioneering model of county-based natural histories, which emphasized systematic observation and influenced subsequent regional studies across Britain.^[3] As the first keeper of the Ashmolean Museum, his curatorial standards— including detailed cataloguing and public accessibility—established an enduring template for natural history museums worldwide.^[4] Historians of science have highlighted Plot's empirical methods, such as his use of questionnaires and on-site investigations, as key contributions to the transition from antiquarianism to modern scientific inquiry, though his recognition was initially overshadowed by more prominent contemporaries like Robert Hooke.^[31] This appreciation was revived in 20th-century works, including Robert T. Gunther's Early Science in Oxford, which underscored Plot's role in fostering interdisciplinary natural philosophy.
