Carmen Bambach
The Complete Chronological Leonardo
The practice of drawing, for Leonardo, was the practice of thinking itself.
— Carmen Bambach
The Scholar
Carmen C. Bambach is a Curator in the Department of Drawings and Prints at the Metropolitan Museum of Art in New York and one of the foremost living authorities on Leonardo da Vinci's drawings and manuscripts. Her four-volume Leonardo da Vinci Rediscovered (2019), published by Yale University Press, is the most comprehensive study of Leonardo's complete output ever undertaken.
Bambach represents the culmination of Pedretti's chronological revolution, taken to its logical extreme. Where Pedretti dated individual pages and corrected Richter's references, Bambach attempts to place every surviving drawing, painting, and manuscript page by Leonardo into a continuous chronological sequence, integrated with a detailed biographical narrative.
The result is monumental: four volumes, over 2,400 pages, with more than 1,200 illustrations. It took decades of research across collections worldwide. It is, in effect, a day-by-day biography of Leonardo's creative life — as close as scholarship can get to following him through his studios, workshops, and wanderings.
The Biographical-Chronological Method
Everything in sequence — drawings, paintings, manuscripts, and life events woven together
The Four Volumes
| Volume | Period | Coverage |
|---|---|---|
| Volume I | 1452–1500 | Youth in Florence, Verrocchio's workshop, first Milan period (The Last Supper era). Leonardo's formation as artist and beginning as notebook-keeper. |
| Volume II | 1500–1508 | Return to Florence, Cesare Borgia campaign, Battle of Anghiari, the Mona Lisa period. Peak of Leonardo's painting career alongside explosive scientific inquiry. |
| Volume III | 1508–1519 | Second Milan period, Rome, France. Peak anatomy studies, Codex Leicester, late paintings (St. John, Salvator Mundi debates). Leonardo's final years and death. |
| Volume IV | Reference | Catalogue of all Leonardo drawings, comprehensive bibliography, concordances, indexes. The reference apparatus that makes the other three volumes usable. |
The Organizational Principle
Bambach's method is strict biographical chronology. Within each chapter (typically covering a few years), she interleaves:
- Biographical context — where Leonardo was living, who he was working for, what commissions he held
- Paintings — the works in progress during that period, their documentary and physical evidence
- Drawings — preparatory studies, independent studies, and notebook pages, dated by physical and stylistic evidence
- Manuscript entries — relevant notebook passages, placed in their biographical moment
- Attribution analysis — careful separation of Leonardo's hand from that of pupils, collaborators, and copyists
The effect is immersive. You don't read about "Leonardo's anatomy" as an abstract category — you read about what Leonardo was dissecting in the winter of 1510, in a hospital in Milan, while simultaneously revising a painting and planning a canal system for the French governor. Everything is placed in the lived reality of a specific time and place.
Key Contributions
1. Drawing as Central Evidence
Bambach, as a drawings curator, places Leonardo's drawings at the center of her analysis — not as illustrations of text but as primary evidence of his thinking process. Her connoisseurial expertise allows her to distinguish Leonardo's hand from his pupils' with precision that textual scholars alone cannot achieve. She can identify which strokes on a sheet are Leonardo's and which were added by Melzi or other assistants.
2. Workshop Dynamics
Bambach pays unprecedented attention to Leonardo's workshop — his pupils, assistants, and collaborators. She shows how drawings and paintings moved between master and pupil, how Leonardo's style was transmitted and transformed. This collaborative dimension is often invisible in earlier scholarship that focused on the lone genius.
3. Attribution Rigor
Some of Bambach's most consequential arguments concern what is not by Leonardo. Her work has clarified the boundary between autograph works and workshop productions, provoking (and sometimes settling) debates about controversial attributions.
4. The Physical Page
Building on Pedretti's codicological methods, Bambach examines the physical properties of every sheet — paper type, dimensions, watermarks, media (chalk, ink, silverpoint), damage patterns — to date and locate it. Her catalogue in Volume IV is the most detailed physical inventory of Leonardo's drawings ever compiled.
Assessment
What Bambach Gets Right
- Comprehensiveness — the most complete catalogue of Leonardo's output ever assembled
- Integration — paintings, drawings, and manuscripts treated as a single interconnected body of work
- Biographical grounding — every work placed in its specific historical moment
- Drawing expertise — brings a curator's eye for physical evidence that purely textual scholars lack
- Workshop context — finally treats Leonardo as a working artist in a collaborative environment, not an isolated genius
- 21st-century synthesis — incorporates discoveries and debates from the last 40 years of scholarship
What It Misses
- Subject access — to find all of Leonardo's thoughts on water, you must read chronologically through all four volumes
- Accessibility — 2,400 pages at scholarly density; this is not a book for the general reader
- Price and availability — the four-volume set costs hundreds of dollars; libraries, not individuals, are the primary audience
- Contested datings — as with all chronological approaches, many individual datings remain debatable
- Leonardo's text — as a drawings specialist, Bambach's treatment of the literary content is less detailed than Richter's or Pedretti's
Legacy (So Far)
Leonardo da Vinci Rediscovered was published in 2019, timed to the 500th anniversary of Leonardo's death. It was immediately recognized as the major Leonardo publication of the 21st century — reviewed widely, debated intensely, and cited as the new standard reference for Leonardo's chronology.
Bambach's work represents the state of the art in biographical-chronological Leonardo scholarship. It is the book that future scholars will work from — and against — just as Pedretti worked from and against Richter. The cycle of compilation, correction, and reinterpretation continues.
Bambach's four volumes are the closest thing we have to a complete map of Leonardo's creative life. But even 2,400 pages can't fully capture a mind this restless. What they can do is show you the trajectory — how the young painter in Florence became the old scientist in France, and all the notebooks, drawings, and paintings that marked the journey. That trajectory is what Phase D of this project will try to make navigable. -D
