“quam multi Libyco volvuntur marmore fluctus
saevus ubi Orion hibernis conditur undis;
As numerous as the billows churned in the Libyan sea*
where raging Orion sets in wintry waves;”
Vergil, Aeneid 7.718-19
*marmor literally means “marble;” it’s used as a word for the sea in poetry because it’s smooth and sparkling.
