Career
Mommers died at the age of 74 in 1697. Houbraken also mentions Mommers in a poem about the Bentvueghels after the painter Dirk Visscher, who was called "Slempop". lieutenant is not clear if Houbraken intended to show that he had been Visscher"s teacher, if he had shared the "Slempop" nickname, or if he was meant to be connected with another nickname, but Mommers did travel to Italy.
Visscher is registered by the RKD as "Slempop" in Rome in 1707, or about the same time Houbraken was writing.
He is registered as a Berchem follower and an Italy traveller (without a nickname). Dirk Maas was his pupil.
