Early 19th century map of Morocco in fine original colour

A decorative map of Morocco in fine original colour, also showing Madeira and the Canary Islands. The title cartouche depicts Moors, a serpent, lion and ostrich. Under the map are prospects of Marrakesh and Meknes. Johann Christoph was the son of Johann Baptist, and took over the family business on his father's death in 1724. However he only survived his father by six years, dying at the age of twenty-nine. From then on the firm took on the rather anonymous appellation 'Homann's Heirs'.
