Piranesi was born in Mogliano Veneto, near Treviso, then part of the Republic of Venice. His father was a stonemason. His brother Andrea introduced him to Latin and the ancient civilization, and later he was apprenticed under his uncle, Matteo Lucchesi, who was a leading architect in Magistrato delle Acque, the state organization responsible for engineering and restoring historical builings.
He died in Rome in 1778 after a long illness, and was buried in the Church he had helped restore, Santa Maria del Priorato. His tomb was designed by Giuseppi Angelini.Wikipedia
