Archbasilica of St. John Lateran
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.
