[EX Q]: Paragraph- Sent 1: On his return to Nuremberg in 1495, Durer opened his own workshop (being married was a requirement for this).
Sent 2: Over the next five years his style increasingly integrated Italian influences into underlying Northern forms.
Sent 3: Durer's father died in 1502, and his mother died in 1513.
Sent 4: His best works in the first years of the workshop were his woodcut prints, mostly religious, but including secular scenes such as The Men's Bath House (ca.
Sent 5: 1496).
Sent 6: These were larger and more finely cut than the great majority of German woodcuts hitherto, and far more complex and balanced in composition.
Sent 7: It is now thought unlikely that Durer cut any of the woodblocks himself; this task would have been performed by a specialist craftsman.
Sent 8: However, his training in Wolgemut's studio, which made many carved and painted altarpieces and both designed and cut woodblocks for woodcut, evidently gave him great understanding of what the technique could be made to produce, and how to work with block cutters.
Sent 9: Durer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block.
Sent 10: Either way, his drawings were destroyed during the cutting of the block.
