All of the patterns in Spode's "Caramanian" series were copied from, or in a very few cases, inspired by aquatints in Views of the Ottoman Empire, published in London in 1803 by Robert Bowyer.  The artist, Luigi Mayer, of German extraction but raised in Rome, accompanied Sir Robert Ainslie, the British ambassador to the Ottoman Empire, on his travels.  He also produced similar books on Palestine and Egypt.  The border elements for the "Caramanian" series come from aquatints in Oriental Field Sports, which was also the source for Spode's "Indian Sporting" series.
