According To The Ge'ez script
The World's Writing Systems (Peter T. Daniels and William Bright, eds., Oxford University Press, 1996) reviews the Aksumite inscriptions that first show Ge'ez written with vocalisation, a fourth-century CE innovation that is not in dispute, and canvasses three explanations for why it happened then: an internal development inside the Aksumite royal chancery seeking a more precise script for administration; a response to the newly Christian court's need for scripture translated and taught with unambiguous vowels after Aksum's conversion under King Ezana; and influence carried by vocalised Indian scripts reaching the Aksumite court through Red Sea trade contact. Comparing the timing, the epigraphic evidence and the trade record for each explanation, the volume's contributors find none conclusive, since Aksum's fourth-century contacts touched all three at once; the dating of the change is settled, its cause is not.
