Quandiu stat Colisaeus, stat et Roma;
quando cadet Colisaeus, cadet et Roma.
quando cadet Roma, cadet et mundus.
(Pseudo-Bede, Excerptiones patrum &c., PL 94.543)

As long as the Colisaeus stands, so Rome stands.
When the Colisaeus falls, Rome falls too.
When Rome falls, the world falls too.
(tr. Brian Schmisek)

‘While stands the Coliseum, Rome shall stand;
When falls the Coliseum, Rome shall fall;
And when Rome falls—the World.’
(tr. George Gordon ‘Lord’ Byron, Childe Harold’s Pilgrimage 4.145)
