😁 In childhood, we had a set of encyclopedias. Anything we wanted to know, we’d look up. My problem was, I’d notice something else of interest, and by the time I read it and pulled out a few more volumes to get the related subjects, I’d forgotten what I’d originally wondered about.
BTW, the quarry of Mons Porphyrites is even more interesting, imho.
Also, the Via Hadrianus — when that was finally surveyed by archaeologists, they found the stashes of original water jugs still in place along its length, and it was apparent that the only time the road may have been used was by its builders.

I remember that well! But, now that old age is upon me, I get to relive that every day. "Now why did I come to the bedroom?"
"...the quarry of Mons Porphyrites"
That was mentioned in the article I was reading: "the only known source of the purple "imperial" variety of porphyry in the world." I'd never even heard of it before. Isn't it beautiful?
