At his death in 1570 Cock left behind the most prominent print publishing establishment in Europe north of the Alps. His widow Volcxken continued the publishing house until her death in 1601. In 1572 she published a book by Dominicus Lampsonius called "Pictorum aliquot celebrium Germaniae inferioris effigies" (literal translation: "Effigies of some celebrated painters of Lower Germany"), a set of 23 engraved portraits of artists with short verses in Latin printed below them. Hieronymus Cock had been working on this publication at the time of his death. The quality of the 23 prints was outstanding as they had been made by some of the leading engravers of the time such as Johannes Wierix, Adriaen Collaert and Cornelis Cort.
