I wonder if anyone happens to know where I could find out about the manuscript tradition of the works of Porphyry? In particular I am interested in De antro nympharum (On the Cave of Nymphs; discussing this episode of the Odyssey). The only material I could find online was an 18th century Dutch edition which said that none were accessible to the editor, who based his text on earlier editions, but that he thought some must exist in libraries, perhaps in Spain.

Obviously what I need is a modern critical text, but since I am nowhere near a library, if anyone happens to have any information I'd be most interested.

I'd also be interested in material on De abstinentia, his letter to Marcella, etc. I did read that heaps of mss exist for the Vita Plotini, all of them derived from a defective ms; but the only ones mentioned were two from Munich ('Monacenses'), and since the source was very old it would be optimistic to presume this was still their abode.

All the best,
