Although you may have read with indifference my past post on the book Anthologia Graeca Carminum Christianorum, perhaps this will capture your fancy. Just today I was paging through the Google Books site when I discovered a classic favorite of mine, Digenis Acritas, which is an anonymous Byzantine epic written in Greek. I have read an English translation of it before, but the only full version I could find on Google Books was a side by side Greek poetry and French prose version.
If you know French, that’s great. If you know Greek, that’s even better. For me, I can read Greek a lot better than French, so I think I’ll just read the original this time. If you’d like to give it a shot as well, feel free to download this PDF of the book. All I did was take Google Books’ file and add PDF bookmarks for easier navigation, so here it is for free, only 13.7 MB: Les Exploits de Digénis Akritas
This version of the poem is from the Trabzon manuscript, which is one of the lesser-known manuscripts, though not the oldest. For a free book, I am quite impressed!
