Giorgio Valla

In existographies, Giorgio Valla (1447-1500) was an Italian academic, mathematician, and translator, noted for []

Overview
In c.1490, Valla began to acquire and secure a number of high-valued Greek science manuscripts, such as a copy of Archimedes Codex A, Ptolemy’s Almagest, and works by Euclid. (Ѻ)

In 1501, Valla, in his posthumous De Expetendis de fugiendis Rebus Opus, supposedly presented some of the early pages of Hero’s Pneumatica; and at least partial translations (Ѻ) of Hero’s Pneumatica date back to the 12th century. [3]

Quotes | On
The following are quotes on Valla:

“The first book of Cardano's De subtilitate (1550) was devoted to the general principles of ‘matter, form, vacuum, the repulsion of bodies, natural motion, and place’; his discussion of the various devices that some claim prove the existence of the vacuum are derived in part from Valla. But Cardano must have had a source beyond Valla, since he described a machine that Valla had omitted (Pneumatica 1.37). Elio Nenci, Cardano's modern editor, suggested that he also relied on the preliminary discussion of the vacuum omitted by Valla, but I see no evidence of that—Cardano never mentions the interparticulate vacuum, for instance.”
