On the Silenus figure, see note. In his essay Silent Alcibiadis for the 1515 Adages, Erasmus writes,
'...For it seems that the Sileni were small images divided in half, and so constructed that they could be opened out and displayed; when closed they represented some ridiculous, ugly fluteplayer, but when they opened they suddenly revealed the figure of a god!' (Translated Margaret Mann Phillips, Erasmus on His Times: A Shortened Version of the Adages of Erasmus, Cambridge University Press, 1967, p. 77.)
