It is more than likely that Philo knew the postbiblical Wisdom literature, in particular the Wisdom of Solomon. and was influenced by it. The obvious identification of Logos and Wisdom in the Wisdom of Solomon is a case in point. Wisdom (Greek sophia) plays a prominent role in Philo as well and is yet another power among the divine powers that acts as an agent of creation. Whereas the Logos, as we have seen, is responsible for the intelligible world, Wisdom would seem to be responsible for the world perceived by the senses.
