What technology was used to build the Palaestra in Pompeii?

Question

The one located next to the amphitheatre

Answer 1

As my long deceased father used to say, 'brute force and ignorance'. In fact, not much of the latter, but quite a bit of the former. The Romans had stone and timber to build with. They therefore probably used timber scaffolding and timber for any formers, possibly necessary to hold the pediment in position during building. The stone used for the pillars was probably hauled into position using a simple 'A' frame or even a primitive crane. Remember, the Romans had a very large number of slaves readily available to do heavy jobs - and they were not protected by any Health and Safety legislation.

Answer 2

I dont' know what the Palaestra in Pompeii looks like but the basics materials of Roman architecture where carved stone,limestone cement and bricks baked in ovens.
Their greatest innovation was the arc,witch utilizes plain geometry ( to cut the stones at the proper angle ),and that enabled them to support more weight than the post and beam method used by the Greeks.
