This article adapts portions of the author's dissertation on Ugaritic epistolography. It includes a brief justification for the renewed study of the corpus of Ugaritic letters, particularly from a structural perspective; discussion of the vatious criteria on the basis of which the corpus may be defined; and a typological classification of the letters founded on the structure of their introductory formulas as well as the relational terminology employed in the letters themselves. Finally, the picture of the Ugaritic epistolary tradition which emerges from such a typology is evaluated against the wider background of cuneiform letter-writing in Late Bronze West Asia.
