James Elroy Flecker. You might like him, considering he was a classicist and orientalist, and most of his poems are about Antique or Islamic history or culture. Very unfashionable nowadays I'm sure, what with generally having rhyme in every line, but there are very, very few poets who have his talent for picking the right words even when having to rhyme.
Really? No French? I don't think besides Flecker I could recommend any English or Latin poets you don't already know. I've read very little poetry honestly, and most of what I've read was Flecker, Tennyson (In Memoriam AHH is absolutely incredible - if you haven't read it, do) and Coleridge. Oh, and Paradise Lost.
Come to think of it, poetry is the one and only field in which I'm relatively well-read in my native Dutch - better than in any other language. But I don't suppose Dutch poetry would help you at all. In prose it's like I go out of my way to avoid my native language...
Now you've got me wondering whether I know any women poets in Latin. Hell, scratch that, female writers in any genre at all. Kind of drawing a blank...
Female poets I've enjoyed in English: Emily Dickinson, Christina Rossetti (mostly just Goblin Market), Sylvia Plath (her diaries more than her poems actually) - like I said, nobody you don't already know.
I'd be definitely interested in that too. I skimmed through a book with some of her poems (original + translation) the other day - reminded me of the good old days in HS when we read her, there's only small fragments left but those do contain some great stuff.
