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,

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
So this could be called "analemmatic shadow plane sundial" perhaps?
(Note the date scale must be reversed as well.)

Very neat John!
But I don't think it works. Not even if south-facing.
The problem is that you are halving the angle through which you turn the
dial. That affects the geometry of the elliptical dial. You can't just
renumber the hour marks. The sun's azimuth (measured from south) at 2pm is

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.

Several of the wanted demands can be realized.

Dear Alison,
I think the experts have already told you what you need to know.
Of course, re-aligning the drive to run North-South would help a little.
This should be easier for Mr Phillips than re-aligning the Earth's axis.
Placing the whole estate on a turntable would be an alternative allowing

You have had a number of replies from experts greater than I, and they
all say the same thing which I can't add to. I especially liked the one

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
Since it's not April First, I can only conclude that this an outstanding

Good luck, Alison!
I'll let the real experts address the weight of evidence, but you are
quite correct, and Mr. Phillips is wrong. While many types of sundials can
indeed be "adjusted" to operate in any location, they cannot be adjusted
to arbitrary orientation.
For the simplest argument you might
