Vitruvius: On Architecture, Volume II, Books 6-10 (Loeb Classical Library No. 280)

I am currently reading right now. So far it’s been a good read. I do have one suggestion one should read the technical terms at the back of the book first. It will help you from flipping back and forth to know what is being described.

Great translation. Easy to read. Book is full of gems. Don't build anything without reading these.
