This is because the parents’ bodies often preserve a quantity of latent seeds, grouped in many combinations, which derive from an ancestral stock handed down from generation to generation. From these Venus evokes a random assortment of characters, reproducing ancestral traits of expression, voice or hair; for these characters are determined by specific seeds no less than our faces and bodily members.
