Hi Sara, Fer, John D. and Gianni: First, thanks Fer for confirming that a monofilar dial does not necessarily have to have a thread, string or cable gnomon. This was confusing.
Would the "monofilar" classification include both azimuthals and (hour angle) Singletons? What should we call the Singleton sundial? According to Sara and Gianni, it is technically an hour angle horizontal (with pole style) which tells Standard Time. But it is awkward to describe it as such in our discussions. We need a term that is short and sweet. I like "monofilar" in that it describes a Singleton dial in one word, However I also dislike monofilar in that it seems to require a thread-type gnomon, with isn't so. I am belaboring this point because I think the Singleton dial is the sundial that might be the solution to the azimuthal's gnomon height problem. It has all the advantages of an azimuthal and less of the disadvantages (Although hour line compression is still a problem on the inner rings). I think several of us would be interested in constructing a Singleton dial if we could find a software program for it. Thanks, John Carmichael
