The Twin Brothers

In Greek mythology Castor and Pollux, twin sons of Zeus and Leda, made into a constellation (Gemini) and thus considered gods. Their chief interest was in the safety of mariners (they had been granted power over wind and waves). Many ships of that era had ensigns (or figureheads) on their bows. The ship that brought Paul from Malta to Italy (after the first ship had been wrecked, Acts 27) had as its ensign a replica of the Twin Brothers (Acts 28:11).
