Using unpublished documents, the author further elaborates the history of the Contarini degli Scrigni palaces
in Venice. It is now possible to distinguish at least three different phases of construction: a late 15th century
gothic palaces, a second palace from the end of the 16th century, and an annex building from the early 17th
century. Two drawings from Andrea Palladio’s workshop which were hitherto identified with palazzo Thiene
Bonin-Longare at Vicenza in fact were made for the second construction phase of palaces Contarini degli
Scrigni. Palladio’s project was not realized, but the existence of (now) at least three different proposals for the
Contarini palace raises new questions about the authorship of the second construction phase, previously attributed
to Vincenzo Scamozzi, but more probably built by a Venetian “proto” inspired by Palladio’s proposals.
