To Jacobus, Presbyter and Monk.
They who have made the vigour of their manhood bright by virtuous industry hasten happily towards old age, gladdened by the recollection of their former victories, and for old age's sake rid of further struggle. This joy I think your own piety possesses, and that you bear your old age the more easily for the recollection of the labours of your youth.
