Francesco di Giorgio
Mariano di Jacopo (1382 – c. 1453), called Taccola ("the jackdaw"), was an Italian polymath, administrator, artist and engineer of the early Renaissance. Taccola is known for his technological treatises "De ingeneis" and "De machinis", which feature annotated drawings of a wide array of innovative machines and devices. Taccola's work was widely studied and copied by later Renaissance engineers and artists, among them Francesco di Giorgio, and Leonardo da Vinci.
