Up for Presentation Today: SETTING A SOLAR CALENDAR with 1/ ZENITH PASSAGE DAYS AND 2/ HELIACAL RISING STARS. INCA CALENDAR METHODS FOR SETTING A SOLAR CALENDAR 1) SHADOW OF A GNOMON (VERTICAL We’ll take these STICK) or PINHOLE IMAGE OF THE one-by-one. SUN ALONG A MERIDIAN LINE {EGYPTIAN, CHINESE, EUROPEAN} ALL WERE USED 2) RISING OR SETTING POINTS OF THE BY ANCIENT SUN ALONG THE HORIZON {HOPI, EGYPTIAN, CELTS, etc etc} PEOPLE BUT TRADITION 3). “ZENITH PASSAGE DAYS” = THE TWO DAYS PER YEAR THAT THE SUN DIFFERED IN GOES EXACTLY THROUGH THE ZENITH DIFFERENT IN THE TROPICS (-23.5O TO + 23.5O) LOCATIONS AND 4). DAY THE SUN FIRST BREAKS THE CULTURES. HORIZON IN THE FAR NORTH 5). “HELIACAL RISING” OF CERTAIN KEY STARS (SIRIUS/SOTHIS, PLEIADES) THE YEAR IN THE TROPICS SEASONAL YEAR NOT AS CRITICAL TO MEASURE ACCURATELY. LENGTHS OF DAYS AND NIGHTS DO NOT VARY SIGNIFICANTLY OVER THE YEAR AND THE SUN’S RISING AND SETTING POINTS DO NOT CHANGE SO MUCH DURING THE YEAR AS AT MID- LATITUDES. BETWEEN THE TROPICS OF CANCER AND CAPRICORN THE SUN ATTAINS THE ZENITH AT NOON TWO DAYS PER YEAR. THESE “ZENITH PASSAGE DAYS” ARE LISTED IN HOMEWORK #3 AND IN THE NOTES. ZENITH PASSAGE DAYS CAN BE USED TO SET A SEASONAL CALENDAR ACCURATELY…..BUT ONLY IN THE TROPICS. IF SOMEONE COULD DETERMINE WHEN THE SUN GOES EXACTLY THROUGH THE ZENITH, the calendar could be re-set.

INTRODUCING THE Q’ERO, DIRECT DESCENDENTS OF ANCIENT INCAS OF THE ANDES My Q’ero Astronomy Mentor, Santos the Elder At the Puno-level village of the Hatun Q’ero clan Hatun Q’ero has 3 village locations at different altitudes: 1. Puno: 14,000-16,000 feet where Llama and Alpaca are herded 2. Quechua: 9,000-11,000 feet where potatoes are grown and celebrations are held 3. Yunga: < 8,000 feet in the Jungle where corn is raised and nobody lives IMPORTANT DATES IN THE INCA YEAR • Mid-May: Pleiades (Colca or “Storehouse”) disappears from the Sky and calendar officially ends for 37 days while the Pleiades are not seen in the sky • FULL INCA YEAR IS 365- 37 = 328 DAYS • AFTER 328 DAYS THERE FOLLOW 37 DAYS WHEN PLEIADES ARE NOT SEEN IN SKY AND “MAMA PACHA” LIES FALLOW • Mid-June: Colca reappears in morning sky, a heliacal rising and the Qoyllur Rit’i (Star of the Snows) pilgrimage and celebration is held. Prognostication involving planting of crops at or around this time. • Winter Solstice (held on June 24th) Inti Rymi ceremony in Cusco at the Coriacancha, in Plaza de Armes and at Sacsayhuaman • Planting time in Cusco (Solar “nadir” passage day) Qoyllur Rit’i (Star of the Snows) pilgrimage Originally an Inca Festival and sacred pilgrimage to honor and bring back a small part of the glacier which provides the beginning of the rivers of life as they descend to Earth from Mayu. Held when Pleiades first visible in the Morning Sky Partly taken over by the Catholic tradition that a boy celebrating Qoyllur Rit’I witnessed a “miracle” seeing a figure of Christ in a rock underneath which the boy was buried.
