Book of legends? (5)
I believe the answer is:
atlas
'book of legends?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for atlas that I've seen before include "North African mountains - mythical Titan" , "Titan who supported the heavens" , "In Greek myth, a Titan made to support the heavens" , "Plans" , "He had the world on his shoulders" .)
