Foebus abierat ("Phoebus had gone") is a medieval Latin poem, authorship unknown, composed near the end of the 10th century in Northern Italy. Described as "hauntingly beautiful" and "one of the joys of medieval poetry," it is an erotic dream-vision lyric spoken by a woman who grieves the departure of her lover Phoebus, brother of the Moon. Although the language is ecclesiastical Latin, none of its content is explicitly Christian. Jane Stevenson speculated in her book Women Latin Poets that this "highly original poem" was written by a nun.
