A series of hymns of ancient Greece.
Ranging from recounting myths, sometimes at length, to bursts of short lyric. Some of it will be familiar, and some not at all -- the Hymn to Ares in particular.
Translation matters. I read an idiomatic one this time, and it tried to bring it into modern English as much as possible. More unfortunately, it was a 1970s translation and bears quite definitely the mark of it, several phrases sheriek of the decades.
Even so, you get the effect of the original Greek in places, with the stock adjectives and epithets building up an effect not found in modern works.
