Letter LXV. To Principia. A commentary on Ps. XLV. addressed to Marcella’s friend and companion Principia (see Letter CXXVII.). Jerome prefaces what he has to say by a defence of his practice of writing for women, a practice which had exposed him to many foolish sneers. He deals with the same subject in his dedication of the Commentary of Sophronius. The date of the letter is 397 a.d.
