Votive portrait in the context of Mérode Altarpiece

The Virgin of Mercy is a subject in Christian art, showing a group of people sheltering for protection under the outspread cloak, or pallium, of the Virgin Mary. It was especially popular in Italy from the 13th to 16th centuries, often as a specialised form of votive portrait; it is also found in other countries and later art, especially Spain and Latin America.

Usually the Virgin is standing alone, though if angels hold up the cloak, she is free to hold the infant Christ. She is typically about twice the size of the other figures. The people sheltered normally kneel, and are of necessity shown usually at a much smaller scale. These may represent all members of Christian society, with royal crowns, mitres and a papal tiara in the front rows, or represent the local population. The subject was often commissioned by specific groups such as families, confraternities, guilds or convents or abbeys, and then the figures represent these specific groups, as shown by their dress, or by the 15th century individual portraits. Sometimes arrows rain down from above, which the cloak prevents from reaching the people.
