Re: Article about Armenian sundials
Interesting physical as well as philosophical discussion about "inaccurate" dials. One possible bottom line is simply what did humans want from a time piece. It seems a mass dial or any other "inaccurate" device must have met their needs and thus was for them a valuable item. Religious meetings, civic activities, and so on would be served well. If "inaccurate" dials get together those who needed to congregate, at the same "inaccurate" time, then is not the objective achieved.

Dear Willy, You say... > The Armenian sundials are more a building > ornament than an instrument to measure the > time. These are variants of the standard European sundials used for indicating 'unequal hours', at least approximately, in medieval times. Several thousand survive in England alone. They divide the daylight period from sunrise to sunset into 12 parts. Unfortunately, these parts are not equal in time and their relationship varies with the time of year. If the dial is vertical, due south-facing, and on the equator (and the gnomon is horizontal and perpendicular to the dial plate) then such a dial would work perfectly. In Armenia, at 40N, they don't perform so well but they they still divide the period sunrise to sunset into 12 parts. It is just that these divisions are not in the correct places and are not of equal length. The examples in the photographs seem very nicely made.

Re: Article about Armenian sundials
The Armenian sundials are more a building ornament than an instrument to measure the time. The sundial scene is divided into 20 or 24 parts at equal angles (ie of 18 or 15 degrees). The shadow of a gnomon will indicate different time periods depending on the date.
