The Sect of the Phoenix (original Spanish title: La secta del Fénix) is a short story by Argentine writer Jorge Luis Borges, first published in Sur in 1952. It was included in the 1956 edition of Ficciones, part two (Artifices). The title has also been translated as The Cult of the Phoenix.
Essentially the story is an extended riddle, the mysterious description referring to a commonplace fact (as Borges points out in the prologue to Artifices). The probable and common answer is that the riddle refers to sexual intercourse, and Borges himself confessed as much. However, in relation to the debate on Borges' sexual orientation, it is argued by some that the secret Borges had in mind was, more specifically, homosexual intercourse or homosexuality in general; to support this, they point to such clues as “scattered across the face of the earth, […] only one thing — the Secret — unites them and will unite them until the end of time”, which do not fit well with the hypothesis of sexual intercourse in general.
