Here are a few translations I found.Graecia capta ferum uictorem cepit et artis
intulit agresti Latio.Horace Epistulae 2. 1. 156-157.
Some quotes have Romam instead of ferum,
Captive Greece took her fierce victor hostage and
brought the arts to rustic Latium.Conquered Greece took her uncultivated conqueror captive and
invaded rustic Latium with the arts.Captive Greece took captive her savage conqueror,
and brought civilisation to barbarous Latium.Captive Greece has captured its wild captor.
Captive Greece took captive her rude conqueror.
