Philo Judaeus De Mutatione Nominum 111

[111] by which seven daughters are frequently intimated the powers of the irrational part of the soul, the power of generation and the voice, and the five outward senses, tending the flocks of their father; for by means of these seven powers it is that all the progresses and increases of their father, the mind, exist in the perceptions which are produced from him. These, then, coming each to its appropriate object, the power of sight to colours and shapes, the sense of hearing to sounds, the faculty of smelling to scents, taste to flavours, and all the other faculties to those objects which are adapted for their exercise do in a manner imbibe some of the external objects of the outward senses, until they have filled all the channels of the soul, and from these channels they give drink to the sheep of their father; I mean by these sheep that most pure flock of the reason which bears safety and ornament at the same time.
