Input: Consider Input: Paragraph- Sent 1: Durer exerted a huge influence on the artists of succeeding generations, especially in printmaking, the medium through which his contemporaries mostly experienced his art, as his paintings were predominately in private collections located in only a few cities.
Sent 2: His success in spreading his reputation across Europe through prints was undoubtedly an inspiration for major artists such as Raphael, Titian, and Parmigianino, all of whom collaborated with printmakers in order to promote and distribute their work.
Sent 3: His work in engraving seems to have had an intimidating effect upon his German successors, the "Little Masters" who attempted few large engravings but continued Durer's themes in small, rather cramped compositions.
Sent 4: Lucas van Leyden was the only Northern European engraver to successfully continue to produce large engravings in the first third of the 16th century.
Sent 5: The generation of Italian engravers who trained in the shadow of Durer all either directly copied parts of his landscape backgrounds (Giulio Campagnola and Christofano Robetta), or whole prints (Marcantonio Raimondi and Agostino Veneziano).
Sent 6: However, Durer's influence became less dominant after 1515, when Marcantonio perfected his new engraving style, which in turn travelled over the Alps to dominate Northern engraving also.
Sent 7: In painting, Durer had relatively little influence in Italy, where probably only his altarpiece in Venice was seen, and his German successors were less effective in blending German and Italian styles.
Sent 8: His intense and self-dramatizing self-portraits have continued to have a strong influence up to the present, especially on painters in the 19th and 20th century who desired a more dramatic portrait style.
Sent 9: Durer has never fallen from critical favour, and there have been significant revivals of interest in his works in Germany in the Durer Renaissance of about 1570 to 1630, in the early nineteenth century, and in German nationalism from 1870 to 1945.
Sent 10: Durer's study of human proportions and the use of transformations to a coordinate grid to demonstrate facial variation inspired similar work by D'Arcy Thompson in his book On Growth and Form.
Sent 11: The Lutheran Church remembers Durer as a great Christian annually on April 6, along with Lucas Cranach the Elder and Hans Burgkmair.
Sent 12: The liturgical calendar of the Episcopal Church (USA) remembers him, Cranach and Matthias Grunewald on August 5.
Question: Who was not intimidated by Durer in producing large engravings?.

Output: Leyden.
