Two artists brought in at biblical landfall (6)
I believe the answer is:
ararat
'biblical landfall' is the definition.
(I've seen this in another clue)
'two artists brought in at' is the wordplay.
'two' shows that letters should be duplicated.
'artists' becomes 'RA' (Royal Academy of the Arts).
'brought in' is an insertion indicator.
'ra' duplicated is 'rara'.
'rara' put inside 'at' is 'ARARAT'.
(Other definitions for ararat that I've seen before include "original dry dock" , "Mount (the Ark''s last resting place)" , "Final resting place of Noah's ark" , "Turkish Mount on which Noah's Ark is said to lie" , "Mount on which Noah's Ark is said to have landed" .)
