The text Περὶ σεισμῶν πραγματεία (On Earthquakes) is a treatise from the Roman era, likely written sometime between the 2nd and 6th centuries CE. The specific author of this work is unknown. During this period, many writers explored natural phenomena, but their works were often compiled anonymously or have been lost over time.

This treatise represents the ancient study of earthquakes, which was part of natural philosophy rather than a modern scientific discipline. Such works typically combined reports of actual seismic events with theories about their causes. According to modern scholars, these explanations ranged from naturalistic ideas—like underground winds or vapors—to interpretations involving divine forces. Beyond theory, these writings had a practical purpose, sometimes offering advice on constructing buildings that could better withstand tremors.

The significance of this and similar treatises lies in their attempt to rationally explain a powerful and frightening natural event. They mark a transition from purely mythological stories toward systematic, observation-based inquiry. Although the specific text On Earthquakes may not survive intact, the ideas from this tradition were copied and preserved, influencing later periods.
