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