Hi all! I've just recently joined the list. Probably just a simple question: In times past, people measured the time through temporal hours, ie. the amount of daylight was divided into twelve equal parts, and so the hour varied throughout the year. Now, how was this hour-length measured? If a sundial was used, was each hour marked on each "day-line" and found with the nodus (assuming a horizontal dial)? As far as I can see the main problem is that the first hour for each day begins slightly earlier or later and so shifts the hour lines out again (ie. a zero-error _and_ an expansion error if you like).
