Philo Judaeus De Sobrietate 29

[29] Memory, therefore, exists best when meeting with manly and solid natures, in respect of which it is looked upon as younger, having been brought forth late; but forgetfulness and recollection, almost from the earliest birth of a man, dwell alternately with every one, on which account recollection has the precedence in point of time, and is placed on the left hand by the wise man when he is arranging the two in order; but memory will share the chief honours of virtue, which the lover of God, receiving eagerly, will think worthy of a better portion by himself.
