Current knowledge
Castle Howard
After Giorgione
Gaston le Foix and Page
Note that the work cited in Castle Howard is only a possible match with the seventheenth-century record. The work is clearly similar to Giorgione and School, Portrait of a Warrior and his Groom, Uffizi Gallery 911, 90 x 73 and a Giorgione in the Accademia.
