He wrote a Latin phrase-book, entitled It is called Quadriga from its being composed from four authors. The work is valuable as preserving many passages from some of Cicero's lost writings, and from Sallust's History. He first gives a phrase generally, then an example, thus: Firmatus illius rei, Sallust. Hist. iii. Ad Cyzicum perrexit firmatus animi. -- Prudens illarum rerum, Sall. Hist. i. Prudens omnium quae senatus censuerat. The following words he arranges under the letter K :-- Kave, kareo, kaptus, khao (abl. of chaos) kassus, klaudus, kalleo, kalco, kausaius, klam.

In some MSS. the work is called &c.; in others, On the authority of the former MSS. it has often passed under the name of Fronto, and under his name it was published by Angelo Mai, from a MS. much mutilated, especially in the latter part. But after what Fronto says on Cicero and other authors, it seems highly improbable that he would have employed himself in composing such a work from these authors. He would have chosen some of his favourite writers, Ennius, &c. It is possible that the work may be an extract by Arusianus from a larger work by Fronto, which larger work would have been composed from a greater number of authors, including those which Fronto most admired.
