I am an engineer by training. I am a closet genealogist and that interest turned me into a an amateur historian. I have taught classes on the early christian church with special emphasis on it relationship with the Roman Empire. I find this fascinating, especially as we relate to how the learnings might apply to society today.
As an engineer, you would appreciate the section in the letters from Pliny to Trajan, in which Pliny has uncovered tremendous fraud and abuses in the province of Bithynia. 3,500,000 sesterces spent on a aqueduct that doesn’t work — 10,000,000 sesterces on a theater with improper foundation (cracks in the walls)— considering that Trajan’s architect was the very famous Apollodorus, (Harbor at Ostia and the Pantheon), Trajan was not too happy with the thought that slip shod engineering was occurring in other regions of the empire.
