It would be even more useful if pictures (or alternatively a drawing/diagram) of each dial type, or showing each dial attribute, were available at one web site.

Most of us know this for different types of well known dials, but it would be fun to elaborate from a didactic point of view. Then have fun fitting into the taxonomy odd balls - like reflecting light dials, dials at the bottom of pools, etc. Its just a thought, - Ben Frank Evans wrote: > > Greetings once more, fellow dialists, > > It seems to me that in the same way as we have difficulty in naming > various forms of time (local apparent time, zonal true time, etc.) we > lack words to describe your ordinary run-of-the-mill sundial.
