I’m sure Tony Moss would be happy to explain it, Douglas!
In short, it’s an Equatorial dial, as I recall. The dial plane is parallel to
the Earth’s equator, and the little stubs of gnomons

Hi Roderick,
Was it perhaps an Erickson Polar Equatorial Dial that you had in mind?
See one example in Denver, Colorado, at:

The NASS registry lists about 12 dials of this type.
Best regards
Dear Douglas,
As Roger Bailey suggests, your message indeed
merits a response.
You have now had plenty of explanation from
Roger and indeed from Tony Moss who designed
and made this exquisite monumental sundial!
Roger notes that it has an equatorial disk

I’ve always thought that the “summer” side of dials like this should show
daylight saving time.
Unfortunately, the authorities refuse to change the clocks at each equinox, so
there would be some offset.
BTW, I have one of these “Tony Moss equatorials” and mine is adjustable for
latitude, but
Here is my take on this type of sundial.
Easy to make and use - and economical. to boot.

Hi,
Though it's impractically large (c 3m in diameter) the design of the
equatorial sundial at Jaipur (properly: the Nare Valaya Yantra) makes it
the easiest one to read of all those I've seen. Here's a tiny snippet
from a postcard (can't lay my hands on my photo at the moment). In
In a previous post (24 Jan. 2013), I thought a sundial in a photo was neat and
wondered if there were plans for it. As a relative newcomer, I don't even know
what kind it is.
That post was apparently completely misinterpreted by an irritable being as
something having to do more with those
struck off
the list for persistent annoying misbehavior. Let's keep it that way,
tolerating the occasional interesting off topic excursions.

Interesting indeed, but, if the exact time of solstice happens to be at
night, it would not show the word? For the text suggests that it's that
precise.

Hi Jim,
