Photius (Codex 99) gives an outline of the contents of this work and passes a flattering encomium on the style of Herodian, which he describes as clear, vigorous, agreeable, and preserving a happy medium between an utter disregard of art and elegance and a profuse employment of the artifices and prettinesses which were known under the name of Atticism, as well as between boldness and bombast. He appears to have used Thucydides as a model to some extent, both for style and for the general composition of his work, often introducing speeches wholly or in part imaginary. In spite of occasional inaccuracies in chronology and geography, his narrative is in the main truthful and impartial[citation needed].
