People have long been fascinated by the heavens, striving to comprehend the movements of celestial bodies and the mysteries of the cosmos. Across cultures and throughout history, this curiosity has shaped intellectual life, influencing the creation of calendars, navigation systems, and our understanding of seasonal and astronomical cycles. In this lecture, we will explore key concepts of ancient Greek astronomy and examine how the sky was envisioned and represented. We will consider the major cosmological models that arose in the Classical and Hellenistic periods, and explore how celestial phenomena impacted daily life—from agriculture and weather forecasting to healing practices and ritual traditions—leaving their imprint on texts, inscriptions, and material culture.
