There are quite a lot of scattered late Latin poems around, often attached to the works of Cyprian or Tertullian in manuscripts or early editions. Some are interesting. This article discusses them, and I have a bunch on my Tertullian site under “spurious”.
One of these is a poem of 85 lines here, which talks about a certain senator who has apostasised and become a devotee of the Magna Mater, Cybele.
I’ve just discovered that an English translation exists, unpublished:
THE “CARMEN AD QUENDAM SENATOREM”: DATE, MILIEU, AND TRADITION by BEGLEY, RONALD BRUCE Ph.D., The University of North Carolina at Chapel Hill, 1984, 303 pages; AAT 8415790
I hope someone will get hold of it from the UMI database so I can take a look at it. It contains interesting details about Cybele, I believe.
