Spells and Philtres is a collection of poems by Clark Ashton Smith. It was released in 1958 and was the author's fifth book and second collection of poetry to be published by Arkham House. It was released in an edition of 519 copies. The book was a second stop-gap volume following The Dark Chateau. It represented Smith's poetry while the more extensive Selected Poems was being prepared which did not ultimately appear until 1971. The collection also includes several translations of French and Spanish poems. Clérigo Herrero, however, is not a real person and the poem is actually a composition of Smith's.
