Tiburzio was the son of Bartolomeo Passerotti, and his carreer begun in the shadow of father. But they had some disagreements, and Tiburzio moved to Venice, where he arrived before 1580 to stay until 1589. Until some decades ago, his only known Venetian work was the Election of Lorenzo Giustiniani as Patriarch of Venice, in Palazzo Ducale.

This paper aims to give a new consistency to the Venetian sojourn of Tiburzio. Recently new paintings have appeared, correctly referred to the artist in his Venetian period, thanks to which we can draw a more precise picture of his residence. The Lorenzo Giustiniani, formerly dated around 1589, must be considered his debut, perhaps dating from shortly after the fire of Palazzo Ducale in 1577.

Through new attributions and some unpublished works, the author reconstructs the path of Tiburzio in Venice, and proposes to recognize his presence in the church of San Zulian, where he painted the Crucifixion among the canvases illustrating the Passion of Christ, and four Virtues on the ceiling.

He worked closely with Leonardo Corona, and perhaps their influences were mutual.

The old opinion, according to which Tiburzio was forced to retire from Venice shortly after his arrival, because of the failure of the Lorenzo Giustiniani, can be definitively discarded.
