Dear Friends in Zelenka, sorry again for my english.
We know that there are no sure portraits of Jan Dismas Zelenka (although the findings of the recent study by Stockigh and Johannes showed that our Zelenka was also fond on painting). Yet, looking for Zelenka on google, everybody can see at least two portraits attributed to him: one, of course, is the portrait of his teacher Fux, so we can defer; the other, however, is taken from one painting of Balthasar van den Bossche (Flemish, 1681-1715), titled "Musicians on a terrace, playing lute, cello and oboe, in a classical architectural setting, in 1713". So my question is, how is it possible that the man playing the violone (is it a violone?) could truly be our Zelenka?
this is the link to the portrait:
