the palace was remodelled after 1486 by a follower of pietro lombardo for the patrician giovanni dario, secretary to the venetian senate, diplomat, and merchant. after dario's death in 1494, it passed to his daughter, marietta, who was married to vincenzo barbaro, the son of giacomo barbaro and owner of the neighboring palazzo barbaro-wolkoff. marietta's sons received possession of the house in 1522. before that time, the senate rented it on occasion as a residence for turkish diplomats.
