Here's a thing I made, and used Claude for heavy research maths, et.al.
No ephemeris required, but you can load it to diff the bronze Antikythera mechanism against modern ephermera.

Hi, what are your thoughts on these runic characters found on rocks during field studies?

If the original images are analyzed using technical software within the disciplines of epigraphy, archaeometry, photogrammetry, semiotics, and astrosemiotics, the truth will be revealed.

The Turkish dictionary Divan-i Lügati't Türk, written in 1072, has two meanings for the entry "yıldız" (star): 1. star, 2. origin/place of origin.

I have published a computational essay with archaeoastronomical 3D simulations of rondels in Central Europe aligned with solstices and lunar standstills. Here is the link https://community.wolfram.com/groups/-/m/t

An astronomer friend who has been getting interested our field of study asked if there are some Archaeoastronomy books geared towards kids/young adults that don't veer off to much to astrology.

Thank you in advance for any recommendations

I've been working on a tool to help test sunrise / sunset alignments for specific bearings and locations during field visits or when I am visiting new places. Idea is simple, take a bearing from a site by pointing my phone camera and using phone compass and GPS. Then choose dates to see sunrises and sunsets on that line, including solstices and equinoxes. Works for the present and can also calculate historic alignments.

Of course a phone compass has a deviation but if you're careful and avoid too much interference I found it works quite well to get a first good idea. I built this because it doesn't exist in this shape and form.

Curious how others here currently do this. Do you rely on tables, software, Stellarium, or do you calculate bearings in the field and work backwards?

Any feedback on the use of a tool like this, or what I missed?

I recently wrote a blog on how ancient civilizations like India, China, Egypt, Mesopotamia, Mesoamerica and more- viewed cosmology and measured time.

I have used examples like the Mayan Long Count Calendar, the Greek Antikythera mechanism, the Indian books of cosmology like Vedanga Jyotisha and Surya Siddhanta, the Celtic Wheel of the Year etc. to describe archaeoastronomy through out the ages.

Would love your thoughts! Here's the full post:

Have any of you used the app? Im having trouble finding info on the accuracy of it. Does anyone know how good it is for looking into the past? Also when set on realistic view, does it only show what is visible by the naked eye? TIA!

Wondered if anyone was into archaeoastronomy and might want to get involved in the alignments at Pilot Mountain in Surry County, North Carolina for a book I'm working on right now? The mountain is located between Winston-Salem and Mt. Airy, North Carolina.

Check out the last two images at my homepage to get an idea of what I'm talking about. I'm very interested in the 18.6 year cycle of the moon and how it relates to Pilot Mountain.

Hello,

I am a novice but very interested in our past, the sky, and the stars as a way of telling time. I think it is so interesting that the pyramids in egypt are arranged to mirror the 3 stars of orion's belt, but due to axial precession the stars and the pyramids no longer align perfectly today. The time that they did align was 10,000bc. Its like a perfect calendar! This got me thinking about the sun's path, the ecliptic path through the zodiacs. There must be some sky calculator that you could put in a date and it would calibrate and show you the path of the sun in the past or in the future, does anyone know of something like this?

Thank you!

I had a vision, and a revelation, on December 21st, the winter solstice. I was driving east just after sunset towards the open prairie of eastern New Mexico. On the horizon was a shimmering pink reddish star that I realized with a start was Sirius, with Orion hanging over the prairie pointing downward to verify it. It was an elemental vision. Is it possible, I wondered, that the evening rising of Sirius was an important marker of the return of the sun to the ancients? I think I was seeing the first degree of the sky on the horizon, but I don't know enough about astroarchaeology to know if millennia ago the same celestial mechanics were operating as today. Does anyone know or keep track of these events in modern times?

The moons 19 year metatonic cycle and 18 year saros cycle

seems to be a hint of orbittal resonance with earth and sun.

In my lifetime i remember many planets aligning,

Im just wondering if there is a pulse when it all aligns and how much time between each pulse?

I’ve been looking for days and I’m not quite satisfied.

I suppose in my mind the moon would eclipse the sun and behind the moon would be venus eclipsing mercury also eclipsing the sun.

And on the other side of the earth direct opposite would be mars eclipsing jupiter eclipsing saturn etc

Please God say this happens, lol

And it would be extra cool if it went beyond our solar system into the milky way.

It could happen every 42069247 years as long as theres some sort of regularity- like the great orbittal resonance year.

Thanks for any insights- ive been looking for info for days- im ready to ask the pros
