This article had lots of neat pictures of muscle-powered cranes, and a good explanation of how they were used to do things like move 100-tonne obelisks around.

The reproduced pictures and the links to references both look pretty useful for any would-be pyramid building PCs or DMs looking for a construction site illustration.

As an engineer, I love articles like this. Thanks a lot. That should be enjoyable reading later on.

Good article.

If you want to show how things can get done without access to the wheel (or magic) there's this video.
