New Defender's Study Bible Notes
28:11 ship of Alexandria. This grain ship from Alexandria spent the winter months in Malta, probably the harbor of Valleta, as the owner of Paul’s ship had wanted to do at Phenice. Navigation by sailing vessels on the Mediterranean virtually ceased during the winter months.
28:11 Castor and Pollux. “Castor and Pollux” was evidently the figurehead and name of the ship. It was so chosen because the astrological sign of Gemini, the Twins, was considered the favorite sign of many ancient mariners.
