the wife of the emperor Elagabalus, whom he married after divorcing his former wife, Paula. This marriage gave great offence at Rome, since Aquilia was a vestal virgin; but Elagabalus said that he had contracted it in order that divine children might be born from himself, the pontifex maximus, and a vestal virgin. Dio Cassius says, that he did not live with her long; but that after marrying three others successively, he again returned to her. It appears from coins that he could not have married her before A. D. 221. (D. C. 79.9; Herodian. 5.6; Eckhel, vii. p. 259.)
