In Grotto Landscape with a Hermitage, how is the Grotto painting as a genre discussed?
De Momper is considered to be the most important exponent of grotto painting: These are paintings in which a rock grotto or cave is the focus of the painting. The caves are refuge for hermits, serve as a place of pilgrimage (as in this painting) or serve as the background of a mythological story. Further representatives of grotto painting are Cornelis van Dalem (approx. 1530–1573), Jan Brueghel the Elder (1568–1625) and Paul Bril (approx. 1553–1626). Another grotto landscape by Joos de Momper and Jan Brueghel the Elder is in the Liechtenstein Museum in Vienna, also here with a reading hermit.
De Momper's name was so closely linked to rock and mountain landscapes that he was named  Judocus de Momper Pictor montium Antwerpiae (Joos de Momper, Antwerp, Painter of mountains) in the then very well-known  Iconography, a series of pictures by well-known painters after Anthony van Dyck.
