## Pacioli, Luca (1445–1517)Summa de arithmetica, geometria, proportioni
et proportionalita (1494) summarized what was known about contemporary
arithmetic, algebra, geometry, and trigonometry and gave a basis for the
major progress in mathematics which took place in Europe shortly after. Divina proportione (1509), with drawings by none other than Leonardo
da Vinci (surely no mathematical text was more impressively illustrated!),
deals with the golden ratio, a subject
that Paciola treats from an architectural standpoint in a second volume. At his death, Paciola left unpublished a major book, De viribus amanuensis,
on recreational problems, geometrical problems, and proverbs. This makes
frequent reference to Leonardo, who assisted him with the project: many
of the problems in this treatise are also in Leonardo's notebooks. Again
it is a work for which Pacioli claimed no originality, describing it as
a compendium.## Related category• MATHEMATICIANS | ||||||
