The earliest artist to make very small intricate engravings was Altdorfer in 1506–7, probably following the example of Italian niello prints, although their size was in fact no smaller than the bottom end of the very cheap devotional woodcuts made throughout the 15th century. However Altdorfer's printmaking developed in different directions, though he continued to produce some small engravings until the 1520s, by which time the style had been taken up by the Nuremberg artists, the Beham brothers and their close friend Pencz. Hans Sebald Beham and Pencz continued to produce engravings until shortly before their deaths in 1550, which effectively ended the style; Barthel Beham had died in 1540. Barthel is generally considered the most inventive of the Nuremberg trio, but his brother Sebald was much more productive, with perhaps the finest technique, and also copied some of Barthel's prints after his death. Aldegrever was a convinced Lutheran who developed Anabaptist leanings, which perhaps led to him spending much of his time producing ornament prints with no human figures. '' by Hans Sebald Beham; the Little Masters did not let small size deter them from tackling the largest subjects of history painting. The influence of the friezes of Polidoro di Caravaggio is seen here. Their engraving style was based on the work of Nuremberg master printmakerAlbrecht Dürer, who was still living in the city until 1527, and in whose workshop Pencz at least may have trained, and the Italian Marcantonio Raimondi, with whom Barthel Beham is supposed to have worked in Rome. Raimondi, and the exterior fresco friezes of Polidoro di Caravaggio, influenced their choice of subjects and compositional style, to which Northern themes of death and humour are added. The prints of Hans Baldung Grien contain similar treatments of sexual themes. Compared to their contemporaries, devotional subjects are notably absent in the work of the Nuremberg artists, who were all expelled from the city for their religious views in 1525 – an episode that still remains rather unclear. Their prints were very widely disseminated, and both drawn copies and examples of the originals have been found in albums from Mughal India, and their figurative compositions were copied in Limoges enamel and various other decorative media, from bronze plaques to stoneware pottery. In addition many of their prints were "ornament prints", consisting entirely of ornament in the Renaissance style, which as well as being collected were designed to be used as patterns for craftsmen in various media. by Jacob Binck, 2.4 × 8.4 cm. Minor members of the group were Jacob Binck and Hans Brosamer, and there are some prints by a "Master IB", named after his monogram, who may be either Pencz, Sebald Beham, or a separate artist. Other artists who did some work on a similar small scale, but are not usually classified as part of the "Little Masters" group, include: Virgil Solis, Matthias Zundt, Jost Amman, and Conrad Saldörfer in Germany, Hans Holbein the Younger in Switzerland and England, and Dirk Vellert and "Master S" in the Netherlands. The etched work of the Hopfer family is often similar in size and must have appealed to a similar market, as did the rather later work of the French printmaker Etienne Delaune.
