Well-spotted !! Take this pile of garbage:
Suddenly, from Tenedos, through the calm waters twin sea-serpents (I shudder at the memory) breasted the swell and in unison made for the beach. Their necks were held stiffly above the waves, and their blood-red crests towered over the water: the rest of them churned the sea behind, as their bodies looped in a long series of undulations. A noise was produced as the salt-water foamed: and already they were homing in on the land, their blazing eyes flecked with blood and fire as they licked their hissing jaws with flickering tongues.
It's much more interesting in the original Latin as many students will attest, but I think it's better in English and Virgil should bloody well have written it in English.
