This is a List of Amarna letters by size, mostly length X width, and starting with the shortest (in Height). Note: a few Amarna letters are wider than tall, for example EA 290.
It should be understood the definition of "mayor" in the Amarna letters. (The definition of King is relatively obvious). Some mayors are called the "Man Town XXX". The obvious description is to call the mayor a governor, (the man who governs, no matter the size of the City-state; ("governor" means "govern-or"). The power of local governors depended on conflicts, or commercial local successes, or of course the discourses, including the everpresent Habiru, ('Apiru).
