As an interesting example of how the TraCES scope might be applied in practice, the case study of the ‘History of the Episcopate of Alexandria’ and other lesser known texts will be briefly introduced. The case-study is concerned with texts transmitted in a multiple-text manuscript that is preserved in a small church in an isolated area at the border of Ethiopia and Eritrea, an area which was once the cradle of Christian civilization in the northern highlands of the Horn of Africa. The manuscript contains a series of palaeographic and linguistic features which put it into relation with the Abba Garima Four Gospels books, as well as to other ancient biblical manuscripts, that probably make it the oldest non-biblical Ethiopic manuscript. The example appears to be interesting and fruitful for questions of textual and cultural history as well as of language.
