Note 050
Ammianus (xvii. 5) transcribes the haughty letter. Themistius (Orat. iv. p. 57, edit. Petav.) takes notice of the silk covering. Idatius and Zonaras mention the journey of the ambassador; and Peter the Patrician (in Excerpt. Legat. p. 28 [ed. Paris; c. 15, p. 131, ed. Bonn]) has informed us of his conciliating behaviour.
