an abjad written right-to-left (as opposed to boustrophedon like ESA) with letters basically identical to the first-order forms of the modern vocalized writing system (e.g. "k" in the form of "kä"). There were also minor differences, such as the letter "g" facing to the right instead of to the left as in vocalized Geʻez, and a shorter left leg of "l", as in ESA, instead of equally-long legs in vocalized Geʻez (somewhat resembling the Greek letter lambda). Vocalization of Geʻez occurred in the 4th century, and though the first completely vocalized texts known are inscriptions by Ezana, vocalized letters predate him by some years, as an individual vocalized letter exists in a coin of his predecessor, Wazeba of Axum. Linguist Roger Schneider has also pointed out in an unpublished early 1990s paper anomalies in the known inscriptions of Ezana of Axum that imply that he was consciously employing an archaic style during his reign, indicating that vocalization could have occurred much earlier. As a result, some believe that the vocalization may have been adopted to preserve the pronunciation of Geʻez texts due to the already moribund or extinct status of Geʻez, and that, by that time, the common language of the people were already later the Eritrean and Ethiopian Afro-Asiatic languages. At least one of Wazeba's coins from the late 3rd or early 4th century contains a vocalized letter, some 30 or so years before Ezana. Kobishchanov, Peter T. Daniels, and others have suggested possible influence from the Brahmic scripts in vocalization, as they are also abugidas, and the Kingdom of Aksum was an important part of major trade routes involving India and the Greco-Roman world throughout classical antiquity. According to the beliefs of the Eritrean Orthodox Tewahedo Church and Ethiopian Orthodox Tewahedo Church, the original consonantal form of the Geʻez fidäl was divinely revealed to Enos "as an instrument for codifying the laws", and the present system of vocalisation is attributed to a team of Aksumite scholars led by Frumentius (Abba Selama), the same missionary said to have converted King Ezana to Christianity in the 4th century. It has been argued that the vowel marking pattern of the script reflects a South Asian system such as would have been known by Frumentius. A separate tradition, recorded by Aleqa Taye, holds that the Geʻez consonantal writing system was first adapted by Zegdur, a legendary king of the Agʻazyan Sabaean dynasty
