atmosphere, rather than depicting topography. He made a number of Madonnas, single religious figures, and small scenes with comic peasant figures. Prints are highly portable and these works made Dürer famous throughout the main artistic centres of Europe within a very few years. The Venetian artist Jacopo de' Barbari, whom Dürer had met in Venice, visited Nuremberg in 1500, and Dürer said that he learned much about the new developments in perspective, anatomy, and proportion from him. De' Barbari was unwilling to explain everything he knew, so Dürer began his own studies, which would become a lifelong preoccupation. A series of extant drawings show Dürer's experiments in human proportion, leading to the famous engraving of Adam and Eve (1504), which shows his subtlety while using the burin in the texturing of flesh surfaces. This is the only existing engraving signed with his full name. Dürer created large numbers of preparatory drawings, especially for his paintings and engravings, and many survive, most famously the Betende Hände (Praying Hands) from circa 1508, a study for an apostle in the Heller altarpiece. He continued to make images in watercolour and bodycolour (usually combined), including a number of still lifes of meadow sections or animals, including his Young Hare (1502) and the Great Piece of Turf (1503). Second journey to Italy (1505–1507) In Italy, he returned to painting, at first producing a series of works executed in tempera on linen. These include portraits and altarpieces, notably, the Paumgartner altarpiece and the Adoration of the Magi. In early 1506, he returned to Venice and stayed there until the spring of 1507. By this time Dürer's engravings had attained great popularity and were being copied. In Venice he was given a valuable commission from the emigrant German community for the church of San Bartolomeo. This was the altar-piece known as the Adoration of the Virgin or the Feast of Rose Garlands. It includes portraits of members of Venice's German community, but shows a strong Italian influence. It was later acquired by the Emperor Rudolf II and taken to Prague. Nuremberg and the masterworks (1507–1520) Despite the regard in which he was held by the Venetians, Dürer returned to Nuremberg by mid-1507, remaining in Germany until 1520. His reputation had spread throughout Europe and he was on friendly terms and in communication with most of the major artists including Raphael. Between 1507 and 1511 Dürer worked on
