The University of Glasgow Library, Special Collections, identifies the sitters in their print (HA0369) as Edward William Lane (1801–1876) and a Mr. Peddie (or Reddie, or Roddie, or Redding).
Lane, an engraver in London, traveled to Alexandria in 1825 for health. He learned Arabic, took to wearing native dress and resided under the name of Mansoor Effendi. See HA157-HA158, HA369, HA528 and HA607-HA608. The newspaper accounts of the fancy dress ball in the Assembly Rooms in Edinburgh in 1843 referred to "Mr Lane, an Affghan" and to "Mr C Reddie [sic] - as an Affghan - chain armour". The setting is the same as HA528 & HA607-HA608.
