Life and career

Mariano Taccola was born in Siena

 in 1382. Practically nothing is known of his early years of training or apprenticeship. As an adult, he pursued a varied career in Siena, working in such diverse jobs as notary, university secretary, sculptor, superintendent of roads and hydraulic engineer. In the 1440s, Taccola retired from his official positions, receiving a pension from the state. He is known to have joined the fraternal order of San Jacomo by 1453 and presumably died around that date.

Work and style

Taccola left behind two treatises, the first being De ingeneis (Concerning engines), work on its four books starting as early as 1419. Having been completed in 1433, Taccola continued to amend drawings and annotations to De ingeneis until about 1449. In the same year, Taccola published his second manuscript, De machinis (Concerning machines), in which he restated many of the devices from the long development process of his first treatise.

 and accompanied by hand-written annotations, Taccola depicts in his work a multitude of 'ingenious devices' in hydraulic engineering, milling, construction and war machinery. Taccola’s drawings show him to be a man of transition: While his subject matter is already that of later Renaissance artist-engineers, his method of representation still owes much to medieval manuscript illustration. Notably, with perspective

Taccola is also known for pioneering the keel breaker, a lever-based device designed to tear holes in the hull (keel) of a ship using its fork or spike. Primarily used against pirates, though supposedly used by Mediterranean navies.

Interest in Taccola’s work, however, practically ceased some time after his death until quite recently, one reason perhaps being that his treatises only ever circulated as handcopied books, with at least three of them remaining extant today. Taccola’s original manuscripts, whose style turned out to be more sophisticated than those of its copies, were rediscovered and identified in the state libraries of Munich
