Byzantine atlas bore model of the heavens (9)
I believe the answer is:
astrolabe
'model of the heavens' is the definition.
'astrolabe' can be an answer for 'model' (I have seen 'heavenly model' mean 'astrolabe' so perhaps 'model' could also mean 'astrolabe'). I am not certain of the 'of the heavens' bit.
'byzantine atlas bore' is the wordplay.
'byzantine' indicates anagramming the letters (byzantine means complex or confusing).
'atlas'+'bore'='atlasbore'
'atlasbore' is an anagram of 'ASTROLABE'.
Can you help me to learn more?
(Other definitions for astrolabe that I've seen before include "heavenly model" , "navigational aid" , "Old navigation instrument" , "Astronomical instrument of former times" , "Observational device" .)
