Virgil, Aeneid 1.67
‘When the Eton masters first started a boat on the river, one of the boys remarked:
gens inimica mihi Tyrrhenum navigat aequor.’
A race of men hostile to me is sailing the Tyrrhenian sea.
– according to Hugh Platt, Byways in the Classics (Oxford 1905), p.46. The line is from Juno’s speech to Aeolus.
