Bizarrely true view of ancient civilisation (8)
I believe the answer is:
etruscan
'ancient civilisation' is the definition.
(the Etruscans were an ancient people)
'bizarrely true view' is the wordplay.
'bizarrely' indicates anagramming the letters.
'view' becomes 'scan' (I've seen this before).
'true' with letters rearranged gives 'etru'.
'etru'+'scan'='ETRUSCAN'
'of' acts as a link.
(Other definitions for etruscan that I've seen before include "Centaurs (anag) - from an ancient Italian country" , "Old Italian language" , "of bygone civilisation" , "of an ancient civilization" , "from part of old Italy" .)
