On May 19, 363 CE, a powerful earthquake struck the Levant, causing widespread destruction from the Galilee to the Negev. This event is particularly notable for its association with the reign of the Roman Emperor Julian, who was on a military campaign against the Sassanid Empire. The quake was interpreted as an ill omen for Julian's ambitions and contributed to the atmosphere of uncertainty during this period of religious transition.

The earthquake is mentioned in the works of Ammianus Marcellinus and other late Roman historians, who used it to illustrate the theme of divine providence. The event became a part of the literary and religious discourse of the time, influencing Christian and pagan writers who sought to explain such calamities. It is a significant historical marker in the poetry and prose of the late antique period, reflecting the anxiety and change of an era.
