Lorenzo Ghiberti
In the 1860s Fisk was commissioned to design mosaics depicting Lorenzo Ghiberti and Albrecht Dürer as part of a series of portraits of great artists for the 'Kensington Valhalla' in the South Court of the South Kensington Museum (now the Victoria and Albert Museum). Only the painting of Ghiberti was reproduced in mosaic, but Fisk's full sized oil versions for both remain in the museum.
