Longinus

Longinus is the name traditionally attached to the influential Greek literary treatise On the Sublime (Peri Hypsous). It is most often identified with Cassius Longinus, a Greek rhetorician and Platonist philosopher of the 3rd century CE who taught in Athens and later served as adviser to Queen Zenobia of Palmyra, by whom association he was executed by the emperor Aurelian around 273 CE. However, modern scholars widely doubt this attribution, frequently dating On the Sublime to the 1st century CE and treating its true author as effectively unknown (hence "Pseudo-Longinus").
