Here, spiraling petroglyphs are precisely intersected by shafts of light on solstices and equinoxes, cast by strategically placed rock slabs. Furthermore, other structures at Chaco Canyon, such as Casa Rinconada, exhibit alignments with lunar standstills, indicating a profound understanding of both solar and lunar cycles.
Maya Observatories: Venus and the Calendar
The Maya civilization of Mesoamerica developed one of the most sophisticated calendrical systems in the ancient world, intricately linked to their astronomical observations. Their cities, such as Chichen Itza and El Caracol, feature buildings explicitly designed as observatories. El Caracol, with its numerous windows and alignments, is particularly noted for its observations of Venus. The Maya tracked the 584-day synodic cycle of Venus with extraordinary accuracy, integrating it into their complex long count calendar and religious beliefs, as Venus was associated with warfare and rebirth.
Nazca Lines: Ground-Based Astronomical Charts?
The enigmatic Nazca Lines in Peru, vast geoglyphs etched into the desert floor, continue to fascinate researchers. While many theories exist regarding their purpose, some archaeoastronomers propose that certain lines and figures correspond to astronomical alignments, particularly with solstices and constellations. The sheer scale and precision of these earthworks suggest a ceremonial or calendrical function, potentially serving as gigantic ground-based astronomical charts for observing celestial phenomena from a distant vantage point.
