Aut cum scuto aut in scuto
Now, THAT'S engineering!
Believe those are Chariot wheel wear marks. Our present day "engineers" could learn a thing or two...
Hmmm... Same width as today's modern RR tracks? Lemme check the internets.
I read an article that tied the diameter of the Shuttle solid fuel boosters back to the Roman chariots.
And a great story it is
I saw a few in Northern Italy on my visits there.
I was stationed in Augsburg with the Army - it is an awesome path, and see all the old Roman marks\markers around and outside the city.
Just spitballing, but it seems Roman wagons (far more used than chariots, btw) were just about the same width as a WWII jeep.
And, if you measured the spacing, it would be 4 feet, 8.5 inches. Same as US railroads, any 19th century buggy, etc. The Romans had the gauge.
Can't tell the width without a tape, but I think those "ruts" are trenches for drainage. I build roads, and if you don't deal with the water, the road won't last very long!
