Marcella had asked Jerome to lend her a copy of a commentary by Rhetitius, bishop of Augustodunum (Autun), on the Song of Songs. He now refuses to do so on the ground that the work abounds with errors, of which the two following are samples: (1) Rhetitius identifies Tharshish with Tarsus, and (2) he supposes that Uphaz (in the phrase "gold of Uphaz") is the same as Cephas. Written at Rome a.d.384.
