Jerome, Saint. [Letter to Marcella, 388] in Commentarius in Epistolam ad Galatas 307-310

[Letter from Jerome to Marcella]
Jerome agreed to compose this commentary for Paula and Eustochium, but when Marcella's mother died, he decided to send it also to her feeling she needed the comfort. Though the prologue is addressed to Paula and Eustochium, it explains why the work (with the prologue) is being sent to Marcella, and includes interesting comments about her.
