"Writers following [Johannes] Wilde [in 1932] regarded Giorgione's figures as the Three Wise Men on the grounds that one of them may have been black. After [Jaynie] Anderson argued in 1979 that x-raydiographic evidence cannot determine underlying color, the view that the Three Philosophers were Magi has not been repeated".
