A detailed technical drawing of a giant crossbow, or 'balester', designed by Leonardo da Vinci. This illustration from the Codex Atlanticus showcases Leonardo's fascination with military engineering and his ability to conceptualize large-scale mechanical devices. The drawing includes intricate details of the carriage, the bow's construction, and the mechanical trigger mechanism, accompanied by his characteristic mirror writing.
Begin with the Trattato della pittura (1651 Editio Princeps), Leonardo’s celebrated treatise on painting — the only work published in a systematic form, covering light, shadow, color, perspective, and the science of seeing. This is the essential starting point.
The original notebooks reveal Leonardo’s mind at work. The Codex Arundel is the largest and most wide-ranging — 545 pages spanning optics, mechanics, geometry, and architecture, written in his characteristic mirror script. The three Codex Forster volumes (Codex Forster I, Codex Forster II, Codex Forster III) are pocket-sized notebooks covering hydraulics, geometry, and household inventories. The Codex on the Flight of Birds is a focused study of avian mechanics and the possibility of human flight — short, vivid, and prophetic.
The Windsor Castle drawings form the core of Leonardo’s anatomical legacy. The Royal Collection holds hundreds of sheets, here organized by subject: the human body (Notes et dessins sur le corps humain), postures and movement (Notes et dessins sur les attitudes de l'homme), the heart (Notes et dessins sur le coeur et sa constitution anatomique), nerves and vessels (Croquis et dessins de nerfs et vaisseaux), thorax and abdomen (Notes et dessins sur le thorax et l'abdomen), generation and internal functions (Notes et dessins sur la generation et le mecanisme des fonctions intimes), physiognomy (Notes et croquis sur la physiognomonie), and studies of heads (Esquisses et etudes de tetes). Alongside these sit the horse anatomy volumes (Notes et croquis sur l'anatomie du cheval, Vol. 1 and Notes et croquis sur l'anatomie du cheval, Vol. 2) — preparatory studies for the great Sforza equestrian monument. Natural philosophy appears in studies of the atmosphere (Etudes et dessins sur l'atmosphere), canals and hydraulics (Etudes et dessins sur les canaux), geometry (Notes et croquis de geometrie), botany (Croquis et dessins de botanique), architecture (Notes et croquis: architecture civile, militaire et navale), and emblems and rebuses (Croquis et dessins de devises et rebus).
Two major scholarly editions make the manuscripts accessible. I manoscritti di Leonardo da Vinci (Sabachnikoff & Piumati, 1898) and the companion Dell’anatomia, fogli A present Leonardo’s Italian text with scholarly apparatus. Del moto e misura dell'acqua collects his writings on water and hydraulics. The Ravaisson-Mollien series (Les Manuscrits Vol. I, Les manuscrits Vol. 2, Les manuscrits Vol. 6) reproduces the Paris manuscripts with French transcriptions.
For English readers, The Notebooks of Leonardo da Vinci (Richter, 1883) remains the standard compilation — a comprehensive selection with parallel Italian and English text across 1,272 pages.
