    I want to say a big THANK YOU to everyone that has shown interest in the work of this channel and who have shared, subscribed, and supported! It can sometimes be hard to do all this on the side, not just the research which I love, but following through to communicate the ideas and share them in a finished video. I know times are hard for many of you, but if you are able to donate to the channel at even a dollar or two per month on Patreon or a one-time donation on PayPal it goes a LONG WAY to supporting the work. If everyone following the channel on TH-cam or the group on Facebook was able to contribute a small amount, the work could be funded close to full time. In any case, I will continue to do what I love as much as I can. Thank You!

    I'm using a tiny clip from this at the end of my next video, basically using you as a resource for people who prefer to learn on the TH-cams. I'll be linking a couple videos of yours including this one. Thanks for providing this resource, too little on this topic exists.

      Hi! Thanks for linking back to me. It is so true that there isn't enough information out there to help people understand the basics. I hope my work can be of some use toward that end.

    Interesting content. I've been marking the shadows on my back porch for a few years trying to figure out a good place to create an analemma to mark the passage of the sun based on shadows from the corners of the rooftops around my backyard. Still haven't quite figured out the best place to create my analemma. This video had a lot of helpful information. Keep up the good work.

      Love it! Creating features to interact with the sun is great fun. ☀ I also have some marks for where the roof shadow strikes at midday over the course of the year. How do you play to outline the analemma when you find the spot?

      @@ArchaeoastronomyDatabase It really depends on where I ultimately place it...a wall or on the pavement. If it wants to be on the pavement, I will use a chisel and dremel tool to make some marks in the concrete...maybe place some glass marbles in the Solstice and Equinox spots. Might use a little paint. Haven't decided yet. Have to find the right spot first, then I'll plan out the design. Been marking the solstice/equinox shadows out for years, but just haven't found the right shadow configuration. It's a slow process, but a fun one. It slows things down when I have to miss a marking day. You only get four chances a year. It'll get done eventually.

      @@c2rail Sounds great! The analemma is very interesting. In the distant past the north/south length would have been slightly greater but the most noticeable effect over time is the asymmetrical layout of the figure changes when the near/far points in the orbit change relative positions with the solstice and equinoxes, and over VERY long periods the eccentricity of the orbit changes the overall amount of asymmetry.

      @@ArchaeoastronomyDatabase One of the things I love about the analemma is it's asymmetry. Makes an attractive figure.

    I love this channel. There is no one esle (??) that tries to explains how observations were made and recorded in order to transmit knowledge to the next generations before writing and being able to count. It seems to me that modern online astronomy tutorials do not mention how we can calculate for example the distance from earth to sun, how to represent the difficult Mars orbit. Nowadays, learning astronomy starts at the black hole level. It is as if biology only discussed T-Rex. Sad.

    • @ArchaeoastronomyDatabase

      I'm glad you are enjoying the channel. Thanks for your encouragement! It is so true that modern astronomy often overlooks the investigation of observational methods of the past. Even among archaeoastronomers there are few that understand much beyond basic astronomy, and fewer still that understand all the changing parameters that affected the layout of the sky in the past in order to do a whole sky analysis.

    ☀One interesting aspect is that although some of the knowledge would be cultural such as the intervals chosen and where to begin and end the year, the actual astronomical observations that are fit into those constructs are constrained by the realities of the sky at those times and places which we can extrapolate and compare to the specifics of theories and evidence. Keep in mind that counting out the same intervals today would yield slightly different declination values as the near/fast point in the orbit changes configuration over time.

      This is Professor Aleaxander Thom is full flow. he was the originator of Archaeoastronomy. He suggested the megalithic yard 2.72 feet was used by the ancient astronomers designing their monuments in the UK and France.
