The Phoenix and the Mirror; or, The Enigmatic Speculum is a fantasy novel by American writer Avram Davidson, the first volume in his Vergil Magus series.

It was first published in hardcover by Doubleday in February 1969, with the first paperback edition issued by Ace Books in the same year.

[1] As set out in an introductory "Author's Note," the novel's protagonist Vergil Magus is based on the ancient Augustan era Roman epic poet Virgil, in his legendary medieval guise as a great magician.

The book is set in an alternate ancient Mediterranean world and features and concerns Vergil's quest to forge a "virgin speculum" (mirror) for the purpose of divination.

While published first, the novel is chronologically the final volume in the series, following Vergil in Averno (1987) and The Scarlet Fig (2005).
