The Master of Frankfurt (1460–c. 1533) was a Flemish Renaissance painter active in Antwerp between about 1480 and 1520. Although he probably never visited Frankfurt am Main, his name derives from two paintings commissioned from patrons in that city.
He is one of many anonymous artists identifiable by their painting style but not by name. The Master of Frankfurt is, however, often thought to be a Hendrik van Wueluwe, an artist famous in Antwerp around the same time as the anonymous painter but otherwise unconnected to any paintings. in, Wikipedia
