I like this geometric juxtaposition, though I might have made the distinction sharper: as distinct as circle and square?  As distinct as line and circle?

See also the bestellar reviews, complete with rich quote-mosaics, of Adam Nicolson’s magnificent Why Homer Matters, and Logue’s War Music, a muscular rendition of several books of the Iliad. 

‘Distinct as polygon and square.’
