Pompeo Targone (1575 – c. 1630), son of a Venetian goldsmith, was an Italian engineer in the service of popes Clement VIII and Paul V. He built the ciborium tabernacle in the Blessed Sacrament chapel of the Archbasilica of St. John Lateran, and one of the altars in the Basilica di Santa Maria Maggiore. Targone gained notoriety for his inventiveness as a military engineer in the Siege of Ostend (1604) and the Siege of La Rochelle (1627-1628). Targone proposed to block the channel leading to the harbour of La Rochelle in order to stop all supplies to the city, but his structure was broken by the winter weather, before the idea was taken up by the Royal architect Clément Métezeau and the Parisian mason Jean Thiriau. Targone has also been credited with the invention of the field mill in Vittorio Zonca's treatise on mechanical arts.
