Рабан Мавр
A 9th century work by Rabanus Maurus, "De Universo", states: "The Massagetae are in origin from the tribe of the Scythians, and are called Massagetae, as if heavy, that is, strong Getae." In Central Asian languages such as Middle Persian and Avestan, the prefix "massa" means "great", "heavy", or "strong".
