ZH_3_05 — Nazca Lines: Astronomical and Ecological Hypotheses
The Nazca Lines are a vast complex of geoglyphs — ground drawings created by removing the dark, iron-oxide-coated desert pavement to reveal the lighter ground beneath — spread across the arid Pampa de Nazca and surroundi
ZH_3_11 — Arctic and Subarctic Astronomy: Inuit, Sámi, Siberian
The astronomy of Arctic and subarctic peoples — including the Inuit (across Canada, Alaska, and Greenland), Sámi (Fennoscandia), and Siberian cultures (Chukchi, Evenki, Yakut, and others) — represents adaptation to one o
ZH_3_20 — The Inca Ceque System: Astronomical Lines, Sacred Geography & Cusco's Cosmic Order

ZH_3_01 — Maya Astronomical Science: Venus Tables, Eclipse Cycles
The ancient Maya (c. 2000 BCE–1500 CE, with the Classic period c. 250–900 CE) developed one of the most sophisticated astronomical traditions of the pre-modern world — rivaling and in some respects exceeding Babylonian m
ZH_3_15 — Norse Astronomy: Sunstones, Aurvandil's Toe, and Viking Celestial Navigation
The Norse/Viking world (c. 800–1100 CE) developed a distinctive astronomical culture shaped by extreme northern latitudes — long summer days with no true darkness, short winter days with extended night, the aurora boreal
