The so-called Vatican Mythographers (Latin: Mythographi Vaticani) are the anonymous authors of three Latin mythographical texts found together in a single medieval manuscript, Vatican Reg. lat. 1401.[1] The name is that used by Angelo Mai when he published the first edition of the works in 1831.[2] The text of the First Vatican Mythographer is found only in the Vatican manuscript; the second and third texts are found separately in other manuscripts, leading scholars to refer to a Second Vatican Mythographer and a Third Vatican Mythographer.
