Oh, the age-old magic of helping a baby to be born... Of course the women all have their hair down, with no tangles and knots? In medieval times sometimes it helped if the mother-to-be sat on the lap of the man who was the father, but I'm not sure if the Romans already knew that. Especially if the parents weren't married, that is. In a pinch any man would do, but the sympathetic magic said the baby would want to meet its father.

Fish pickle sauce, maid... whatever. ;)
