Arthur B. Chamberlain, Hans Holbein the Younger, Volume 1…
“ THE YOUNGER HOLBEIN’S BIRTH Far more reliable proof as to the correct date of Holbein’s birth is afforded by the fine silver-point drawing by the elder painter, in the Berlin Museum, of the heads of his two sons (Pl. 6) . [75] Between the heads is written “Holbain,” and over that of the younger boy on the right the word “Hanns,” with the age “14” above the name. Over the head of the elder boy on the left the shortened name “Prosy” is still legible. Probably the first syllable, “Am,” has become obliterated in course of time, or it may be that the father merely set down his nickname, “Prosy.” ”
