Let the page lead
Calling Leonardo a genius or an eccentric can become a way of avoiding the evidence. His notebooks offer a better starting point: what is actually on a sheet, and what can we reasonably infer from it?
The V&A’s introduction to Leonardo’s notebooks describes pages containing varied observations, drawings and mirror writing. The arrangement of a surviving notebook is itself something to examine rather than assume.
Observation before explanation
Choose one reproduced page. First describe what you can see without assigning a motive. Are there different subjects? Do words and drawings interact? Which marks appear to be revisions?
Next read the museum’s account. Separate its identification of the material from your interpretation of the working process. A crowded page does not diagnose a personality. A drawing of a device does not prove that a working version was built.
Avoid the convenient anecdote
Stories about unusual habits can make an artist memorable, but a retold anecdote needs an identifiable source and appropriate qualification. This article no longer uses unsupported stories about Leonardo’s character as explanations for his art or scientific interests.
An imagined editor’s task
Suppose you must select three notebook pages for a new reader. Write a caption for each that distinguishes the visible evidence, the museum’s interpretation and an unanswered question. Do not rearrange the pages into a fictional sequence of discovery without saying so.
For a related problem, read about Leonardo’s anatomical work and its possible circulation. Together, the exercises ask how an idea is recorded and how later readers encounter it.
Editorial review
Reviewed on 26 September 2026. Removed unsupported personality anecdotes and completion claims; replaced a repetitive biography with a notebook-reading exercise.
