A. , It is unlikely that Verdoel trained with Rembrandt before his training at De Wet. Verdoel grew up in Schiedam, and could have had his basic training in the nearby city of Delft, perhaps at Bramer.

, A first reconstruction of his oeuvre is attempted in Jager, pp.385-389, 2016.

, Verdoel's oeuvre is quite problematic, because the signed and dated paintings point to at least two painters active with the same name, The paintings dating between 1690 and 1700 are therefore identified as by Adriaen Verdoel

, The date might have been mistakenly read as 1652. However, a genre painting with dancing people in old-fashioned clothing, signed and dated 'Adria Verdoel 1643', differs completely in character, subject and style from the works of either, see illustration in S.

, The listing in the sketchbook is '3 julius is by myn te schilderen ghekomen Pieter Wiggerts voor de soma van 60 gulde jaers int jaer 1656, p.217
