One (quarter) day at a time

Above the only remaining gate into the town, I spotted this relic: a mediaevil 6 hour clock based on Roman 2ndC BCE timekeeping.
The DAY runs from 06:00 to 18:00 divided into
Terce 09:00 until
Sext 12:00 until
None 15:00 until
Vespers at 18:00 when NIGHT started.
During the night Roman guards would stand watch, (being vigilant from which we get VIGILS.)
First from 19:00 to 21:00
Second from 21:00 to 24:00
Third from midnight to 03:00
Fourth 03:00 to 06:00もっと詳しく
