A lingua ignota (Latin for "unknown language") was described by the 12th-century abbess Hildegard of Bingen, who apparently used it for mystical purposes. It consists of vocabulary with no known grammar; the only known text is individual words embedded in Latin. To write it, Hildegard used an alphabet of 23 letters denominated litterae ignotae (Latin for "unknown letters").
