The ancient world was rich in poetry. The ancient authors who most readily spring to mind were either poets themselves (Hesiod, Virgil, Sappho) or recorders of/commentaters upon others' poetry (Snorri Sturulson). Plus, all those anonymous works of poetic genius (see Beowulf).
The modern Pagan movement is just as rich in poetry. I can't remember when I first began reading and collecting modern Pagan poetry. It was well after I came home to/converted to/embraced Hellenismos. I had plenty of the old authors at hand; everyone from the aforementioned Hesiod, Virgil and Sappho to Bacchylides, Callimachus, Catullus, and an assortment of anthologies. It was with great surprise and delight, then, that I found their modern descendants.
There are poems for feast days, poems for holy days, poems to commemorate special occasions, poems in honor of nature, poems for children, poems for the dead, poems for the Gods. Some of these poems appear in fairly mainstream publications (see Parabola), others appear in highly specialized publications (Mythic Delirium), and still others are self-published on websites or in print and ebook collections.* Some are written by openly Pagan authors for a Pagan audience, while others are written with no particular audience in mind but which do (nonetheless) find a home on Pagan bookshelves.
