χρυσίον πραγματευτικόν, Lat. aurum comparatitium.  The gold collected for the equipment of troops.  Cod. Theod. vii. 6. 3.  The provinces of the East, with the exception of Osroene and Isauria, contributed gold instead of actual equipment.  The Ben. note quotes a law of Valens that this was to be paid between Sept. 1 and April 1, and argues thence that this letter may be definitely dated in March, 372, and not long before Easter, which fell on April 8.
