His brother Andrea introduced him to Latin literature and ancient Greco-Roman civilization, and later he was apprenticed under his uncle, Matteo Lucchesi, who was a leading architect in the Magistrato alle Acque, the state organization responsible for engineering and restoring historical buildings.
From 1740, he had an opportunity to work in Rome as a draughtsman for Marco Foscarini, the Venetian ambassador (and future Doge of Venice) to the new Pope Benedict XIV.
In 1764, one of the Pope's nephews, Cardinal Rezzonico, appointed him to start his only architectural work, the restoration of the church of Santa Maria del Priorato in the Villa of the Knights of Malta, on Rome's Aventine Hill.
He combined Classical architectural elements, trophies and escutcheons with his own particular imaginative genius for the design of the facade of the church and the walls of the adjacent Piazza dei Cavalieri di Malta.
[2] In 1776, he created his best known work as a 'restorer' of ancient sculpture, the Piranesi Vase, and in 1777–78 he published Avanzi degli Edifici di Pesto (Remains of the Edifices of Paestum).
Even though the social structure by an aristocracy remained rigid and oppressive, Venice revived through the Grand Tour as the center of intellectual and international exchange in the eighteenth century.
The Caffe degli Inglesi opened several years later, at the foot of the Spanish Steps in Piazza di Spagna, with wall paintings by Piranesi.
With his own print workshop and museo of antiquities nearby, Piranesi was able to cultivate relationships in both places with wealthy buyers on the tour, particularly English.
Informed by his experience in Venice and his study of the works of Marco Ricci and particularly Giovanni Paolo Panini, he appreciated not only the engineering of the ancient buildings but also the poetic aspects of the ruins.
His masterful skill at engraving introduced groups of vases, altars, tombs that were absent in reality; his manipulations of scale; and his broad and scientific distribution of light and shade completed the picture, creating a striking effect from the whole view.
[4] A number of the Views are notable for depicting human figures whose poverty, lameness, apparent drunkenness, and other visible flaws appear to echo the decay of the ruins.
Piranesi's son and coadjutor, Francesco, collected and preserved his plates, in which the freer lines of the etching-needle largely supplemented the severity of burin work.
[4] The late Baroque works of Claude Lorrain, Salvatore Rosa, and others had featured romantic and fantastic depictions of ruins; in part as a memento mori or as a reminiscence of a golden age of construction.
Artists developed a greater self-consciousness in confronting the limited authority of the ancient world, and there was a growing interest in civilizations and the destiny of nations.
[8] Throughout his lifetime, Piranesi created numerous prints depicting the Eternal City; these were widely collected by gentlemen on the Grand Tour.
