Elizabethan portraiture is a fascinating subject, not least because most of the sitters look like nobody on god's earth. Also, they are quite frequently identified as
a) Queen Elizabeth
or
b) Mary Queen of Scots
even when they are male. So arguing the identity of an Elizabethan portrait on the grounds it looks a bit like another portrait is not really the act of a rational being. Still...
Old Essex
Or as old as he ever got, anyway. Note the reddish colour of his beard, and the shield over his right shoulder which has the Essex colours of orange and white.
