Iconography
Saint Nicholas is a popular subject portrayed on countless Eastern Orthodox icons, particularly Russian ones. He is depicted as an Orthodox bishop, wearing the omophorion and holding a Gospel Book. Sometimes he is depicted wearing the Eastern Orthodox mitre, sometimes he is bareheaded. Iconographically, Nicholas is depicted as an elderly man with a short, full white beard and balding head. In commemoration of the miracle attributed to him by tradition at the Ecumenical Council of Nicea, he is sometimes depicted with Christ over his left shoulder holding out a Gospel Book to him and the Theotokos over his right shoulder holding the omophorion. Because of his patronage of mariners, occasionally Saint Nicholas will be shown standing in a boat or rescuing a drowning sailor.
In Roman Catholic iconography, Saint Nicholas is depicted as a bishop, wearing the insignia of this dignity: a red bishop's cloak, a red miter and a bishop's crozier. The episode with the three dowries is commemorated by showing him holding in his hand either three purses, three coins or three balls of gold. Depending on whether he is depicted as patron saint of children or sailors, his images will be completed by a background showing ships, children or three figures climbing out of a wooden barrel (the three slaughtered children he resurrected).
In a strange twist, the three gold balls referring to the dowry affair are sometimes metaphorically interpreted as being oranges or other fruits. As in the Low Countries in medieval times oranges most frequently came from Spain, this led to the belief that the Saint lives in Spain and comes to visit every winter bringing them oranges, other 'wintry' fruits and tales of magical creatures.
