It actually takes a scholarly study to discern that a cargo ship will carry more than one type of cargo. Ridiculous.
I have always suspected that early ships traded in more than just wine. Consider Proverbs 31:
“Who can find a virtuous woman? For her price is far above rubies. The heart of her husband doth safely trust in her, so that he shall have no need of spoil. She will do him good and not evil all the days of her life. She seeketh wool and flax, and worketh willingly with her hands. She is like the merchants’ ships; she bringeth her food from afar.”
I never imagined that this was about a wife keeping her husband drunk on imported wine. I assume this is about the wife’s role in meeting the family’s domestic and nutritional needs including a broad range of foods, a role that was even in 1000 BC supported by the sea trade in the Med.
