The European Society for Astronomy in Culture (SEAC) met Sept. 6–11, 2021 for their annual conference in Stara Zagora, Bulgaria, in the form of a combined on-site and virtual conference. “Cultural Astronomy & Ancient Skywatching” was the theme of the 28th annual SEAC meeting. The papers given covered natural and social sciences, including astronomy, anthropology, history, archaeology, architecture and mathematics. Luwian Studies’ president Eberhard Zangger presented a paper (co-authored with E.C. Krupp, Serkan Demirel and Rita Gautschy) about “The Perennial Cycles of the Universe as Symbolized in Hittite Yazılıkaya.” Fieldtrips in the framework of the conference revealed how astronomical concerns were expressed in human-made constructions and art as early as the Neolithic.
