Steal from Sandro Botticelli (3)
I believe the answer is:
rob
'steal' is the definition.
(robbing is a kind of stealing)
'from sandro botticelli' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ROB' can be found hidden inside 'sandro botticelli'.
(Other definitions for rob that I've seen before include "Mug, say" , "Burgle" , "Steal or purloin" , "shortened form of man's name" , "Take something without the owner's consent" .)
