Damasus wrote many epigrams. Here they are in Latin. They have recently been translated into English, and although not in the public domain for many years, you can actually see quite a bit of it in the Amazon preview.
Here is an epitaph that Damasus wrote for her sister. It is here only in Latin, but with some translation helps. Damasus wrote a hymn to Saint Agatha, here in English, which can also be read on her Feast Day, and a hymn to Andrew.
Damasus presided over the Council of Rome in 382 which issued the Canon of Sacred Scripture, also know as the Decree of Damasus, listing the books agreed upon as Scripture. Here it is in extended form, as the Decretum Gelasianum in 492.
For the first Friday, I recommended a French song, and today, the second Friday, I will recommend two German songs, Lutheran in origin, but close to the Biblical text and in common use today among Catholics (although perhaps not Traditional ones).
