Teaching Sumerian: Text Corpus, Cuneiform Script and Grammar

Our textbook of Sumerian resulted from a lucky coincidence: the two authors discovered that they had worked on an introduction to Sumerian, Laurent starting with cuneiform and the texts, Walther with the grammar. We combined forces, and in the course of our work, we came across aspects we want to share and discuss, including the following ones: (a) Sumerian is only transmitted in specific kinds of texts written in a specific style, phraseology, and grammar. (b) Reading Sumerian texts can not be based on grammar and lexicon alone, but it includes knowledge of the cuneiform script. (c) Should we teach ancient languages in international English only or in different tongues (including German, French, and Arabic)?
