[macas]

Happy New Year ,

Here's a puzzle - a portrait of the famous seafarer Ferdinand Magellan (1480-1521) , writing on the board by an unknown artist . I think that a copy of the famous Italian artist Parmidzhianino ( 1503-1540 ). Original, unfortunately , not found. According to this page, portrait Ferdinand Magellan already has some some valuables But the mystery is this - how could Parmidzhianino napisat portrait of Magellan during his life ? And where the copy of the 19th century ?
Incidentally, the picture in the size of 20 x 16.
