Synesius ' De regno, which claims to be addressed to Arcadius himself, contains a tirade against Goths.

Synesius composed and addressed to Emperor Arcadius a speech entitled De regno, full of topical advice as to the studies of a wise ruler, but also containing a bold statement that the emperor's first priority must be a war on corruption and a war on interpenetration of barbarians in Byzantine army.

The main source for the affair is a mythology à clef by Synesius of Cyrene, Aegyptus sive de providentia, ( 400 ) an Egyptianising allegory that embodies a covert account of the events, the exact interpretation of which continues to baffle scholars.

In order to obtain material for these works, Sigonius consulted all the archives and family chronicles of Italy, and the public and private libraries, and the autograph manuscript of his De regno Italiae, containing all the preliminary studies and many documents not used in print, was discovered in the Ambrosian library of Milan.
