Codex Leicester

The Codex Leicester is a collection of approximately 72 pages of scientific notes, diagrams, and sketches compiled by the Italian Renaissance polymath Leonardo da Vinci between 1506 and 1510 while he resided in Milan.^[1]^[2] Written predominantly in Leonardo's characteristic mirror script on loose sheets of linen rag paper folded into 18 bifolios, the codex explores interconnected themes of water's properties and movements, geology, astronomy, optics, and mechanics, including observations on phenomena such as the blue color of the sky, fossilized seashells in mountains, and the circulation of water through the earth.^[3]^[4] The manuscript's provenance traces back to Leonardo's lifetime, after which it passed through various Italian collectors before being acquired in 1717 by Thomas Coke, 1st Earl of Leicester, from whose estate it derives its name.^[4] In 1980, it was sold at Christie's in London for $5.12 million to American industrialist Armand Hammer, who temporarily renamed it the Codex Hammer.^[5] On November 11, 1994, the codex fetched a record-breaking $30.8 million (including buyer's premium) at a Christie's auction in New York, purchased anonymously by Microsoft co-founder Bill Gates, who restored its original designation and holds it as the only Leonardo notebook in private ownership in North America.^[4] As of 2021, valued at an estimated $130 million, it remains intact and in stable condition, with over 300 illustrations that demonstrate Leonardo's empirical approach to science.^[4] The Codex Leicester holds profound significance as a testament to Leonardo's prescient scientific insights, anticipating concepts like plate tectonics through theories on mountain formation and earthshine via reflections of Earth's oceans on the Moon, while its hydraulic studies influenced his artistic works such as The Virgin of the Rocks.^[3] Exhibited internationally under Gates's stewardship, including at the Uffizi Gallery in 2018–2019, the Minneapolis Institute of Art in 2015, and the North Carolina Museum of Art in 2015–2016, it exemplifies the Renaissance fusion of art and science, offering invaluable glimpses into one of history's most innovative minds.^[2]^[1]^[6]

Manuscript Description

Physical Format

The Codex Leicester is a notebook compiled by Leonardo da Vinci around 1508–1510, consisting of 18 disbound sheets of handmade rag paper in rezzuta format, each folded once to create 36 folios or 72 pages in total.^[7] The work was assembled over two distinct periods, circa 1506–1508 and 1510–1512, with the content divided thematically between investigations of water and observations of terrestrial and celestial phenomena.^[7] Each page measures approximately 19.5 by 27.2 cm (7.7 by 10.7 inches), derived from the untrimmed sheets that originally spanned about 30 by 40 cm when flat.^[8] Leonardo filled the pages with his characteristic mirror script—written in Italian from right to left—interweaving dense textual notes with intricate ink drawings, diagrams, and sketches that illustrate his scientific concepts.^[9] The manuscript's loose sheets were subsequently bound as a single volume, and rebound several times over the centuries to preserve its structure.^[7] In the 20th century, after its acquisition by Bill Gates in 1994, the codex was disbound once more; today, each page is individually mounted between panes of glass for protection and display, restoring it to an unbound state closer to its original format.^[9]

Materials and Condition

The Codex Leicester consists of 18 sheets of handmade rag paper, folded in half to create 72 double-sided pages suitable for Leonardo da Vinci's portable notebook format. The text is written in iron-gall ink, a common medium for Renaissance manuscripts that has naturally aged to a warm chestnut tone over time due to oxidation.^[10] Illustrations and diagrams are executed primarily in pen and ink, with some using wash for shading.^[11] Despite its age of over 500 years, the codex remains remarkably well-preserved, attributed to careful handling and storage throughout its history.^[12] Minor signs of wear include some fraying along edges and occasional staining from prolonged handling, along with light foxing on select pages and subtle ink fading in areas exposed to light.^[13] Conservation reports highlight these issues as typical for paper-based artifacts but note no structural damage that compromises readability or integrity.^[14] Restoration efforts began in earnest in the 1980s under Armand Hammer's ownership, involving scientific analysis and gentle cleaning at specialized laboratories to stabilize the ink and paper.^[14] Following Bill Gates' acquisition in 1994, the codex was disbound and each bifolium mounted between protective glass panels to prevent further abrasion.^[15] Additional professional cleanings occurred in the 1990s to address surface dirt and minor discoloration, after which no major interventions have been required; ongoing preservation relies on climate-controlled storage in the Gates collection to mitigate environmental degradation.

Intellectual Content

Astronomical and Cosmological Ideas

In the Codex Leicester, Leonardo da Vinci explores celestial phenomena through detailed sketches and notes, particularly on folio 2r, where he diagrams the phases of the Moon and elucidates the mechanism of earthshine. He explains that the faint "ashy light" visible on the Moon during its crescent phase results from sunlight reflected off the Earth's surface onto the Moon, demonstrating his grasp of reflected light as the source of lunar illumination rather than any intrinsic glow. This observation, dated circa 1506–1510, integrates principles of optics with astronomy, showing how light propagates through space and interacts with spherical bodies like the Earth and Moon.^[16] Leonardo's writings reject traditional Aristotelian cosmology in favor of empirical evidence, emphasizing direct observation over authoritative dogma. For instance, he describes the Moon's surface as irregular and watery, akin to Earth, challenging the notion of perfect celestial spheres and proposing that mountains and seas exist on other bodies. His diagrams on light reflection, rendered in his characteristic mirror writing, further link terrestrial optics to cosmic events, illustrating how rays bend and scatter to produce visible celestial effects. These ideas position the Earth not as a static center but as part of a dynamic universe governed by observable physical laws.^[17] A key cosmological insight in the codex ties Earth's history to broader universal processes, using fossil evidence to argue for ancient submergence under seas. On folios such as 10v, Leonardo posits that marine shells found on mountaintops are remnants of prehistoric oceans that once covered the land, refuting biblical flood explanations and implying vast timescales of geological and cosmic change. This perspective frames Earth as a living, evolving entity within an immense cosmos, where empirical traces like fossils reveal the planet's transient place amid eternal stellar motions.^[18]

Studies of Water and Geology

Leonardo da Vinci's investigations into water and geology in the Codex Leicester emphasize water's fundamental role in shaping the Earth's surface, portraying it as the "vehicle of nature" that drives geological processes through its ceaseless motion.^[19] He explored how water erodes landscapes, forms sedimentary deposits, and influences mountain building, integrating empirical observations with theoretical insights drawn from his studies of rivers, floods, and tides. These writings, compiled around 1508–1510, reflect da Vinci's interdisciplinary method, linking hydrological dynamics to broader Earth transformations.^[20] A central theme is the cyclical movement of water, which da Vinci conceptualized as a perpetual process from evaporation and atmospheric transport to precipitation and return to the sea, sustaining life's vitality while gradually altering the terrain. On folio 3v, he critiques earlier ideas of subterranean caverns drawing water upward, instead proposing that solar heat distills moisture from the oceans, forming clouds that release rain to replenish rivers and groundwater. This cycle, he argued, exceeds the Earth's volume in water content, with vast reserves stored underground, facilitating erosion and deposition over immense timescales. Da Vinci's descriptions of river erosion, particularly the Arno River's flow, illustrate how currents carve valleys and transport sediments; on folio 15r, he details confluences of tributaries with the Arno, noting how floods accelerate scouring and sediment layering.^[3]^[21]^[22] In geological terms, da Vinci proposed that sedimentary layers result from successive depositions by ancient waters, with marine fossils embedded in mountains as evidence of the Earth's past submersion. On folio 10v, he asserts that shells found atop Apennine peaks originated from a time when the Mediterranean Sea covered much of Europe and North Africa, rejecting biblical flood narratives in favor of gradual, long-term changes driven by water's action. His theories on mountain formation link erosion to structural shifts; folio 36r depicts mountains arising from the collapse and reconfiguration of underground caverns filled with water, rebalancing the Earth's mass and foreshadowing concepts akin to plate tectonics through observations of crustal instability. Da Vinci extended these ideas to ocean tides, viewing them as responses to lunar influence that mirror water's broader erosive power on coastlines.^[20]^[3]^[21] The Codex features numerous illustrations underscoring these concepts, including cross-sections of riverbeds showing erosion patterns and sediment accumulation, as well as diagrams of wave formations and their impact on shores. Da Vinci sketched hydraulic machines to harness water's force, such as devices for channeling flows, and detailed subterranean water networks on folios like 14v, where he illustrated drop impacts and underground conduits that distribute moisture across the landscape. These drawings, often paired with annotations, demonstrate his use of visual analogy to explain complex dynamics, such as water's spherical forms during fall transitioning to angular erosion effects.^[23]^[3]^[20]

Other Scientific Observations

In the Codex Leicester, Leonardo da Vinci explores optics through empirical observations of light phenomena, including an experiment on folio 36r where he uses smoke and black velvet to demonstrate why the sky appears blue, attributing the color to the scattering of light against the darkness beyond the atmosphere.^[3] He also notes the refraction of light, such as in interactions between celestial bodies and water surfaces, providing early insights into how light bends and reflects to create visual effects.^[24] These studies highlight Leonardo's systematic approach to testing hypotheses through simple setups, often accompanied by sketches that visualize the paths of light rays. Leonardo's botanical observations emphasize patterns in nature, particularly on folio 34r, where he sketches the vein structure of leaves and draws analogies between their branching patterns and natural systems, illustrating his interest in growth processes and structural efficiency in plants.^[25] These empirical drawings reveal his method of direct observation followed by detailed illustration to hypothesize about organic development, avoiding abstract theory in favor of measurable forms. In mechanics, Leonardo investigates principles of motion and force, including notes on impetus, percussion, and the behavior of objects in fluids, as seen in sketches of dynamic effects like objects dropped into water on folio 14v.^[3] He conceptualizes devices such as pumps inspired by natural flows, integrating observations of pressure and movement to design machines that harness environmental forces efficiently.^[24] Throughout these entries, dated primarily from 1506 to 1510, Leonardo employs a process of keen observation, tentative hypothesis, and iterative sketching to bridge natural phenomena with practical invention, underscoring his holistic scientific inquiry.^[1]

Historical Ownership

From da Vinci to the 18th Century

The Codex Leicester was compiled by Leonardo da Vinci between approximately 1508 and 1510, during his residence in Milan, as a collection of 18 bifolios (double-sided sheets) of loose paper containing notes and illustrations on astronomical phenomena, the dynamics of water, and geological processes. Upon da Vinci's death in 1519, the manuscript passed to his devoted pupil Francesco Melzi, who inherited the entirety of Leonardo's papers, sketches, and notebooks as specified in the artist's will; Melzi meticulously preserved and organized the collection at the family estate in Vaprio d'Adda near Milan.^[26] Following Melzi's death in 1570, the codex, like many of Leonardo's manuscripts, was inherited by Melzi's son Orazio and subsequently dispersed after Orazio's passing around 1580. The exact path after Melzi remains obscure, entering private Italian collections.^[27] By the mid-16th century, around 1537, it had reached Rome, where it came into the possession of the sculptor Guglielmo della Porta (c. 1500–1577), a prominent artist known for his bronze works and papal commissions; the manuscript remained with the della Porta family for over a century, undocumented in public records but valued for its scientific insights.^[28]^[29] In 1690, the unbound sheets were rediscovered by the Roman painter and antiquarian Giuseppe Ghezzi (1634–1721) in a chest of family papers belonging to the della Porta heirs, prompting scholarly interest in Leonardo's unpublished works.^[30] Ghezzi retained ownership until 1717, when he sold the codex to Thomas Coke (1697–1759), an English Grand Tour collector and future 1st Earl of Leicester; the acquisition reflected Coke's passion for Renaissance art and science during his travels in Italy.^[28] The manuscript arrived in England in 1719, initially housed at Coke's London residence, Thanet House, where it was cataloged in private inventories but received no public exhibition, remaining a treasured possession through the 18th century.

The Leicester Family

The Codex Leicester entered the possession of the Coke family, Earls of Leicester, in 1717 when Thomas Coke, later the 1st Earl of Leicester (1697–1759), acquired it during his Grand Tour of Italy as a young collector of Renaissance art and antiquities.^[31] A contemporary copy of the manuscript was made in Rome before Coke's return, and the original arrived in England in 1719, initially housed at his London residence, Thanet House.^[31] Upon Coke's death in 1759, the codex was transferred to Holkham Hall in Norfolk, the family's ancestral estate, where it joined the expansive library assembled by Coke and augmented by his uncle Sir Edward Coke's earlier collections of legal and historical manuscripts.^[32] It remained there as a prized Renaissance artifact, inherited through successive generations of the Earls of Leicester, symbolizing the family's enduring patronage of scholarship and cultural heritage amid the challenges of estate management and agricultural innovation at Holkham.^[31] The manuscript, cataloged as item 699 in the Holkham Hall library inventories by the 19th century, received limited but significant scholarly attention during its time with the family.^[31] In 1883, the German art historian Jean Paul Richter gained rare access to study it at Holkham Hall, producing the first extensive excerpts and translations in his seminal anthology The Literary Works of Leonardo da Vinci, which highlighted its scientific insights on hydrology and cosmology.^[33] This marked a key moment in da Vinci scholarship, as Richter was the first to examine the codex in detail since its acquisition. By 1909, coinciding with the death of Thomas William Coke, 2nd Earl of Leicester, Italian scholar Girolamo Calvi published the first complete transcription and Italian translation, based on access granted at Holkham; that same year, a photographic facsimile was produced to preserve and disseminate its contents more widely.^[34]^[31] Throughout the 20th century, access remained restricted, with the codex stored securely in the Holkham library among over 10,000 rare volumes and 550 manuscripts, but not on public display to protect its fragile condition.^[32] Occasional viewings were permitted for select scholars, underscoring its status as a private family treasure rather than a exhibited item, though it contributed to the library's reputation as a repository of Renaissance genius. The codex's name, affixed during this period, directly honors the Leicester family and their Holkham estate, reflecting its integral role in their cultural legacy from 1717 until its eventual transfer in 1980.^[31]

Sale and 20th Century Transfers

In the late 1970s, the trustees of the Holkham Estate, facing significant maintenance costs for the historic Holkham Hall, decided to auction the Codex Leicester to generate funds for the property's upkeep.^[35] This decision ended the manuscript's 263-year tenure with the Leicester family, which had acquired it in 1717.^[36] The proposed sale prompted a review under the UK's export licensing regime for objects of cultural interest, as the Codex was deemed a national treasure; however, after deliberation, an export license was granted, allowing the item to leave the country.^[37] On December 12, 1980, Christie's in London conducted the auction, where American industrialist and art collector Armand Hammer secured the winning bid for $5,126,000—a record price for any manuscript at the time.^[38] Hammer, chairman of Occidental Petroleum, outbid other collectors in a highly anticipated event that drew international attention to Leonardo da Vinci's scientific writings.^[36] This transaction marked the first major public sale of the Codex in over two centuries, underscoring the escalating market value of Renaissance manuscripts amid growing global interest in da Vinci's legacy.^[4] The acquisition by Hammer shifted the Codex from British aristocratic hands to American private ownership, bridging its historical European provenance with modern collecting trends. Hammer retained possession until his death in 1990, after which it remained in his estate until 1994, during which period the manuscript became known briefly as the Codex Hammer.^[38]^[39]

Contemporary History

Ownership by Armand Hammer

In 1980, industrialist and art collector Armand Hammer acquired the Codex Leicester at a Christie's auction in London on December 12 for $5,126,000, marking the highest price paid for a manuscript at the time.^[38]^[36] Upon purchase, Hammer renamed it the Codex Hammer to reflect his ownership, a practice he applied to several of his acquisitions to personalize his collection.^[40] This acquisition was funded through a $6 million appropriation from Occidental Petroleum to the Armand Hammer Foundation, underscoring Hammer's tendency to blend corporate resources with personal collecting interests.^[40] During Hammer's 14-year ownership from 1980 to 1994, the codex became a centerpiece of his promotional efforts to elevate Leonardo da Vinci's legacy as a multifaceted genius akin to a Renaissance innovator in business and science. Hammer toured the manuscript extensively, displaying its 72 disbound pages in freestanding cases across 15 museums in nine countries, which collectively drew over 1 million visitors and generated significant media attention.^[40] Notable early exhibitions included a 1981 showing at the Corcoran Gallery of Art in Washington, D.C., and a major presentation at the Royal Academy of Arts in London from November 1981 to February 1982, where it was featured alongside a book illustrated by da Vinci's works.^[41]^[42] Hammer amplified its cultural prominence through personal initiatives, such as securing honorary citizenship from the town of Vinci, Italy—bestowing upon him the title "Armand Hammer da Vinci"—and establishing the Armand Hammer Center for Leonardo Studies at UCLA to foster scholarly research on da Vinci's contributions.^[40] The codex was also housed and displayed at the Armand Hammer Museum of Art in Los Angeles, which Hammer founded in 1990 and which served as a primary venue for his collection.^[43] Hammer loaned the manuscript to various institutions, including libraries and galleries, to broaden public access, though no major conservation or restoration efforts were undertaken during this period, preserving its condition largely intact from prior ownership.^[40] By 1994, amid financial pressures on Hammer's estate following his death in 1990, the codex was appraised at approximately $30 million, reflecting its appreciated value and cultural significance under his stewardship.^[4]

Acquisition by Bill Gates

In November 1994, the Codex Leicester, previously known as the Codex Hammer during Armand Hammer's ownership, was auctioned at Christie's in New York. On November 11, an anonymous bidder—later revealed to be Microsoft co-founder Bill Gates—purchased the manuscript for $30,802,500, including the buyer's premium, setting a record as the most expensive book or manuscript sold at auction at the time.^[44]^[4] Gates' acquisition was driven by his longstanding admiration for Leonardo da Vinci's innovative spirit and the manuscript's embodiment of the intersection between art and science, which resonated with his own pursuits in technology and discovery. He viewed the Codex as a source of inspiration, highlighting da Vinci's curiosity and forward-thinking observations as parallels to modern technological advancement. Shortly after the purchase, Gates had the unbound pages placed in protective glass frames for preservation and limited viewing, and it was briefly showcased in interactive displays at Microsoft facilities through the Codescope project, an early digital tool he developed to allow exploration of its contents.^[45]^[4] In the immediate aftermath, Gates restored the manuscript's original name, Codex Leicester, honoring its 18th-century owner Thomas Coke, Earl of Leicester, rather than personalizing it. The Codex was insured and stored in a secure vault in Seattle, where Gates resides, ensuring its protection as a private collection with no initial public loans. Gates has since described the acquisition as a pivotal influence, noting in interviews that da Vinci's notebook continues to motivate his work by demonstrating the power of interdisciplinary thinking in driving innovation.^[4]^[45]

Exhibitions and Public Access

Following Bill Gates' acquisition of the Codex Leicester in 1994, the manuscript has been loaned for several major public exhibitions, allowing broader access to Leonardo da Vinci's scientific notes while prioritizing conservation. The first display after the purchase occurred at the American Museum of Natural History in New York from October 1996 to February 1997, where it was presented alongside interpretive materials to highlight its scientific significance.^[46]^[47] This was followed by an exhibition at the Seattle Art Museum from October 1997 to January 1998, featuring the full 72-page codex in a dedicated show titled Leonardo da Vinci: Codex Leicester and Leonardo da Vinci's Legacy of Art and Science.^[48]^[47] Subsequent loans included the Phoenix Art Museum in early 2015, the Minneapolis Institute of Art from June to August 2015, and the North Carolina Museum of Art from October 2015 to January 2016, where it was contextualized with contemporary art to explore themes of observation and creativity.^[49]^[50]^[1] A notable international presentation took place at the Uffizi Galleries in Florence from October 30, 2018, to January 20, 2019, under the title Water as Microscope of Nature: Leonardo da Vinci's Codex Leicester, displaying over 80 original pages alongside other da Vinci manuscripts and multimedia aids for enhanced viewer engagement.^[51]^[52] To facilitate wider public and scholarly access, high-resolution digital scans of the Codex Leicester were released by Microsoft-owned Corbis in 1997 as an interactive CD-ROM titled Leonardo da Vinci, enabling users to explore translations, annotations, and high-fidelity images of all 72 pages.^[53]^[54] This digitization effort extended to online platforms in the early 2000s, with portions made available through licensed partnerships, such as a temporary six-month display on the British Library's website in 2009, featuring zoomable scans and contextual essays.^[55]^[56] Interactive kiosks, like the Codescope developed for exhibitions, have further supported digital exploration, allowing touch-screen navigation of the manuscript's contents during public shows.^[57] The Codex has also been made available for scholarly research through selective loans and reproductions, underscoring its value in Leonardo studies. Gates has permitted access for academic projects, including computational analyses of watermarks and inks to enhance readability of the vellum pages.^[58] A landmark contribution to scholarship came in 2020 with the publication of a four-volume facsimile edition edited by Martin Kemp and Domenico Laurenza, providing a high-quality reproduction, new transcription, English translation, and interpretive essays that integrate modern scientific insights with Leonardo's observations on hydrology and cosmology.^[59]^[60] As of November 2025, no major physical exhibitions of the Codex Leicester have been announced, influenced by the COVID-19 pandemic's disruptions to museum programming and ongoing conservation needs to protect the fragile 16th-century paper from environmental stressors. Immersive digital exhibitions featuring replicas or scans, such as the Da Vinci Experience in Florence from June to October 2025, continue to provide public access.^[61] Emphasis has shifted toward digital preservation, with sustained efforts to maintain high-resolution scans and virtual access as primary means of public engagement, ensuring long-term availability without risking the original artifact.^[62]^[63]
