Adda-danu
Adda-danu was the ' mayor' of the city/ city-state of Gazru-(modern Gezer, Israel) of the Amarna letters period, 1350-1335 BC. 'Adda' is the name of the Northwest Semitic god Hadad, and Adda-danu translates as: "Hadad (is the) Judge". Adda-danu is one of the three mayors who ruled Gazru in the 20–year Amarna letters correspondence, the others being Milkilu, and Yapahu.
Adda-danu is the author of one letter, EA 292, ( EA for 'el Amarna'). The letter is entitled: "Like a pot held in pledge". It is of note that some of the 382 Amarna letters contain phrases, quotes, or parables and the title refers to, The Pot of a Debt.
