A Royal Decree of Alexander the Great, as an arbitration on a land dispute between the city of Philippi and local Thracians (presumably of the Edonian tribes), was discovered in a Byzantine basilica at Filippoi (1936) and published in 1984. The inscription, in two columns, bears the names of Leonnatus and Philotas, (possibly the companions), who act as arbitrators who would redraw the boundaries. The units of measurement mentioned, are plethra and stadia.
