Some stones of Rego Grande, known as the 'Amazon Stonehenge'

Some stones of Rego Grande, known as the ‘Amazon Stonehenge’


As soon as the Mail Online report of this historic site said there were 127 stones, an idea occurred. In the lunar Metonic cycle of ~19 years there are 254 lunar orbits (= sidereal months) of the Earth, which is 127 x 2. If this has already been suggested somewhere, I’m not aware of it!

Wikipedia says: ‘the Metonic cycle…is a period of very close to 19 years that is remarkable for being nearly a common multiple of the solar year and the synodic (lunar) month.’

A megalithic stone circle in Brazil hints that the indigenous people of the Amazon may have been more sophisticated than archaeologists first thought.

Rego Grande, known as the ‘Amazon Stonehenge’ after the famous prehistoric monument in Wiltshire, is located in Amapá state, near the city of Calçoene. Experts say the unusual stone arrangement may have been used as a place of worship as well as for astronomical observations related to crop cycles.

Taking its name from a nearby stream called the Rego Grande, the stone arrangement comprises 127 blocks of granite, standing upright in a circle over 98 feet (30m) across. Each of the blocks stands up to 13 feet (4 metres) tall, weighs several tonnes and appears to be irregularly shaped.

The stones appear to to have been arranged to coincide with the winter solstice, when the sun is at its lowest. The shadow of one of the blocks is said to disappear when the sun is directly above it.

The site was first reported by Swiss-Brazilian naturalist Émil Goeldi in the late 19th century, but it wasn’t comprehensively studied until much later.

    More from Wikipedia:

    19 tropical years = 6,939.602 days (12 × 354-day years + 7 × 384-day years + 3.6 days).
    235 synodic months (lunar phases) = 6,939.688 days (Metonic period by definition).
    254 sidereal months (lunar orbits) = 6,939.702 days (19 + 235 = 254). [Talkshop note: 254 = 127 x 2]
    255 draconic months (lunar nodes) = 6,939.1161 days.

    Note that the 19-year cycle is also close (to somewhat more than half a day) to 255 draconic months, so it is also an eclipse cycle, which lasts only for about 4 or 5 recurrences of eclipses.

    In this analysis one lunar orbit is ‘lost’ every 6441 tropical years = 339 Metonic cycles…
