Philo Judaeus De Opificio Mundi 164

[164] For the serpent fighter appears to me to be no other than temperance expressed under a symbolical figure, waging an interminable and unrelenting warfare against intemperance and pleasure. For temperance especially embraces economy and frugality, and pares down the necessities to a small number, preferring a life of austerity and dignity. But intemperance is devoted to extravagance and superfluity, which are the causes of luxury and effeminacy to both soul and body, and to which it is owing that in the opinion of wise men life is but a faulty thing, and more miserable than death.
