Solarium Augusti

The Trail

  1. “how did romans tell time” (google.com)
  2. Roman timekeeping (en.wikipedia.org)
  3. Sundial (en.wikipedia.org)
  4. Water clock (en.wikipedia.org)
  5. Solarium Augusti (en.wikipedia.org)

    Augustus used an Egyptian obelisk as a giant sundial gnomon

What I came away with

Daylight was split into 12 hours whatever the season, so a summer hour in Rome was about 75 minutes and a winter one about 45.

Keep going
