Julia Charlotte Mengs
Julia Charlotte Mengs was a German painter.
Julia Charlotte was born in Bohemia, into the Lutheran family of Danish painter Ismael Mengs, a hofmaler at the court of Saxonian-Polish electors and kings. She was the younger sister of Therese Maron and Anton Raphael Mengs, and also embarked on a career as a court painter. However, in 1765 she entered the Belvedere Convent in the March of Ancona, taking the name of Sister Maria Speranda. She died there sometime after 1806. No work by Julia appears to have survived, although a pastel portrait of her traditionally described as being by her sister has sometimes been suggested to be a self-portrait instead.
