Agostino Ramelli

1610) was an Italian engineer best known for writing and illustrating the book of engineering designs Le diverse et artificiose machine del Capitano Agostino Ramelli, which contains, among others, his design for the bookwheel.

Ramelli was born in Ponte Tresa or Mesanzena, today in Switzerland.

During the Siege of La Rochelle (1572–1573), he successfully engineered a mine under a bastion and breached the fortification,[1] making him popular with his commander, Henri d'Anjou, who later became King Henri III of France.

The book contains 195 designs, over 100 of which are water-raising machines, such as water pumps or wells.
