⁷²"The Ancient Astronomers of Newgrange." Mythical Ireland- Newgrange, Ancient Sites, Myths, Mysteries, Tours and Astronomy. Web. 31 Jan. 2012. <https://mythicalireland.com/blogs/astronomy/ancient-astronomers-of-the-stone-age>
This website is a good starting point for the discussion of ancient astronomers: "There is a dim light which shines from the remote distance of the Neolithic past. It carries a message of wisdom, of understanding, of cosmic awe and inspiration, and astronomical mastery of the highest order. We have regrettably looked upon the ancient people of this land as being primitive, and in some quarters we are told that these awesome constructs with their dazzling size and arcane symbols, are merely tombs, used to bury the dead. Even today, archaeology calls Newgrange, Knowth and Dowth "passage-tombs". I would like to see that title removed, and to install a more accurate and fitting description - something like 'astronomical timepieces' or 'Stone Age observatories'."
In a completely different, passionate and idiosyncratic vein, another website seems to channel Vallancey.
