# Leonardo draws the regular solids for Pacioli's De divina proportione

Date: 1498

## The fact

Around 1498 Leonardo drew regular solids for Pacioli's De divina proportione. The book printed in 1509 is a later carrier. The drawing labour is this Fact. Leonardo da Vinci's documented role is: He drew polyhedra for Luca Pacioli. Pacioli wrote the book; printers later issued it (1509), a neighbouring date.

## Context

Pacioli is the mathematician of record. Sharing plates with him is required. The setting of Leonardo draws the regular solids for Pacioli's De divina proportione is the public file around 1498-02-01. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver edu-[digital-learning-access](/drivers/edu-digital-learning-access) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

## Significance

Improving path from Leonardo draws the regular solids for Pacioli's De divina proportione on 1498-02-01. Mathematical plates are an education path. 1509 print is the book's date, noted as later carrier. The welfare reading on this path is improving.

If a number is not in the two records named above, it is not supplied here.

## What is established and what is not

Established: a sourced public record of Leonardo draws the regular solids for Pacioli's De divina proportione under 1498-02-01 for Leonardo da Vinci. Established: a sourced public record of Leonardo draws the regular solids for Pacioli's De divina proportione under 1498-02-01.

Confidence is stated on the impact path, not hidden in adjectives. Do not treat 1509 typesetting as 1498 drawing. Do not drop Pacioli. Mixed effects of Leonardo draws the regular solids for Pacioli's De divina proportione are separate paths.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.

Shared responsibility is part of Leonardo draws the regular solids for Pacioli's De divina proportione. Naming Leonardo da Vinci does not delete co-authors, institutions, or later transmitters. The lag from 1498-02-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
