'Grass of Parnassus' is a collection of poems by Andrew Lang. Many of the poems are inspired by Greek myths, with some of them bearing these titles: 'Circe's Isle Revisited', 'Lost in Hades', 'Twilight on Tweed', and 'A Ballad of Departure'. Here's an excerpt from 'Circe's Isle Revisited': "Ah, Circe, Circe! in the wood we cried / Ah, Circe, Circe! but no voice replied / No voice from bowers o'ergrown and ruinous / As fallen rocks upon the mountain side."
