Three triologisms demonstrating the strength of the protective masonry encasing Troy; the first being spoken by Agamemnon, chief among the Greek kings at Troy.  As we know, in the end, the walls came tumbling down not by being breached or broken but through subterfuge.  

We’ve been seeking their traces ever since, as anyone who has read archeaological accounts of many-layered may-be ‘Troy’.  

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

‘Zeus son of Kronos has caught me badly in bitter futility.

He is hard: who before this time promised me and consented

that I might sack strong-walled Ilion and sail homeward.’

 

‘… but at this time battle and clamour were blazing

about the strong-founded wall and the bastion timbers were thundering

as they were struck …’

 

‘There the sons of the Achaians might have taken gate-towering Ilion

under the hands of Patroklus, who raged with the spear far before them,

had not Poibos Apollo taken his stand on the strong-built

tower, with thoughts of death for him, but help for the Trojans.’
