OK, so you're ready for New Year's Eve, but still wondering 'Who ever figured out how to pour concrete under water??' Admittedly, it's a common question, and all to often forgotten seconds later.
You probably have Perseus and a latin volume by Vitruvius 'On Architecture' written during Herod the Great's big building boom. It discusses this very problem, along with how to build Roman cities, aquaducts, and so forth. But it's in latin. Up the creek without a paddle.
The above CP has the english (and latin too). And a whole series of interesting books.
Why bid on this?
1. It's cheap. Probably the start-off bid should be higher, but so it goes.
2. When you're teaching Bible class, throwing in very interesting tidbits from the NT time period is immensely interesting to your sleepy audience. Building, farming, looking into the skies (star over Bethlehem?), and so forth.
3. And theologically, it can be somewhat of a puzzler .... I'm speaking of the astronomy in this CP versus the 'gods' at that time. Especially the guys from the east.
Have a good New Year.
