For many centuries, from at least the time of Jerome of Stridon (d. 420), Biblical Aramaic was misnamed as "Chaldean" (Chaldaic, Chaldee).[11][12][13] That label remained common in early Aramaic studies, and persisted up to the nineteenth century.[14][15][16] The "Chaldean" misnomer was consequently abandoned, when further research showed conclusively that the Aramaic dialect used in the Hebrew Bible was not related to the ancient Chaldeans and their language.[17][18][19]
