Episode #118: Lost Technologies of Ancient Egypt - Part 1

We catch up on listener emails and comments and open a couple of 1up Boxes. Then Kyle reads a story about recent cattle mutilations in Oregon and we spend some time discussing the history of this strange phenomena and what the "popular" explanations are.

For the second half of the show, we dive into Christopher Dunn's excellent book "Lost Technologies of Ancient Egypt", looking at the Unfinished Obelisk in Aswan, an anomalous piece of granite with strange tool marks in Abu Roash, and the infamous "Core #7" found by Petrie. All of these objects hold clues as to the methods for working stone that were used by the ancients, and Dunn does an excellent job investigating them.

  2. Sounds like a Wendigo did the killings. Has all the trademarks, and Wendigos are a lot more likely than aliens visiting Earth. At least the Wendigo is already here and doesn't have to travel light years through space.
