Short answers, pulled from the story.
Andrea Mantegna was born in Isola di Carturo, close to Padua, in the Venetian Republic. He became apprenticed to Paduan painter Francesco Squarcione at the age of 11 around 1440.
Most of this fresco cycle disappeared during Allied bombings of Padua in 1944. A surviving sketch for a Saint Stephen fresco reveals nude figures were used before they were painted clothed.
From December 1466 onward he moved his family to reside within Mantua itself. His masterpiece became the Camera degli Sposi or Wedding Chamber inside the Palazzo Ducale.
His workshop produced approximately thirty large plates filled with figures according to usual reckoning. Some experts believe he personally engraved only seven or perhaps none at all.
Hampton Court Palace holds them today as some of his finest invented compositions. The series sold in 1628 along with other treasures to King Charles I of England.
