Agostino Ramelli was an Italian military engineer and mechanic who worked in the fields of fortification and practical mechanics.
Ramelli studied mathematics, mechanics, and engineering under Giacomo di Marignano, who is considered a disciple of Leonardo da Vinci. He first showed his talents as a mechanic during Louis XIII's military campaign by constructing a mine under a bastion.
Ramelli invented many mechanisms that impressed his contemporaries, including their special aesthetic appeal. His most popular creation is the so-called Ramelli Book Wheel, a rotating reading table. Agostino Ramelli positioned his invention as a sleek design that allowed access to several books without having to get up from his seat.
Ramelli wrote and illustrated a book of engineering projects, Le various et artificiose machine ("Various and Artificial Machines"). The book contains 195 designs, over 100 of which are water-lifting machines, such as water pumps or wells, as well as bridges, mills, and so on. This very interesting book for our contemporaries is still published and is still in demand.
