Dear John, What you describe resembles an azimuth sundial. See for instance the Plochingen sundial in Karl Schwarzinger's collection: http://members.aon.at/sundials/bild44_e.htm In this case, there would be no clear-cut alignment with anything, including the (in)famous path... Best regards, Fra

Forgive me, for returning with yet another tiresome proposal: On reflection I suspect Mr Phillips may not be totally wrong-headed. On any one day the azimuth of the shadow of a static human shadow-caster can be marked by a circular arc of hour-marks or indeed by hour-marks fixed along two stra

Nice job. Original, adaptable. I suspect it can be modified to apply to a larger scope of dials than just analemmatic. Not sure the public would go for it aesthetically, but I admire the concept. -Bill Gottesman John Lynes wrote: > I'm grateful for the generous reception you gave to my last

Mr. Philips can insist as much as he likes. However, you might ask if he is related by ancestry to King Canute. Same end result, won't and didn't work. You might consider an analemma on the true north south line, however, it only blurs the issue, not solves it. All dials are presentation devices

Hi Alison, Executive summary: Mr. Phillips can't have it. More detail: the central scale of dates is a projection of the direction of the Earth's axis. This fixes the direction of the date scale on a horizontal dial to point along North-South. Nothing can be done about it (other than tilting the
