Court divided about Durer’s first artistic creation (7)
I believe the answer is:
woodcut
'artistic creation' is the definition.
'court divided about durer's first' is the wordplay.
'court' becomes 'woo' ('woo' can be a synonym of 'court'**).
'divided' becomes 'cut'.
'about' says to put letters next to each other.
'first' indicates taking the first letters.
The initial letter of 'durer' is 'd'.
'cut' put after 'd' is 'dcut'.
'woo'+'dcut'='WOODCUT'
(Other definitions for woodcut that I've seen before include "Relief work" , "Type of print" , "Form of print" , "picture" , "(Print from) incised block" .)
