Pietro Querini was an Italian merchant and navigator, senator of the Venetian Republic. He was born in Venice, the date is not known with certainty.
During one of his voyages he landed, after colliding with a storm, on the rock of Sandøya, a Norwegian island. The inhabitants welcomed Querini and the surviving crew by offering him codfish. Querini is in fact famous for having imported codfish to Venice, presenting it to Doge Francesco Foscari. This is how baccalà mantecato became known in Venice.
