Peter,
That's an good question, and you've already had a couple of informative
replies.
My 2 cents worth is to say that I wish we had a clearer system of
nomenclature. There were conversations a few years back but no
consensus, and I don't think there's any benefit in reopening the topic.
I will say though, that your question demonstrates the overlap between
two aspects of a dial - the type of dial (the physical configuration)
and the time system (type of hours kept) - even though our naming tends
to be based one or the other aspect but not both.
I believe Ildephonse's dial was a Vertical Dial. The system of hours
shown was Mean Time. Wouldn't it be nice if the name told us both bits
of information?

Hi,
A friend recently returned from Port Augusta and sent me photos of a
dial in the Australian Arid Lands Botanic Garden (attached). The
Garden describes it as a 'Projection Dial', but clearly that isn't a
unique name for this form of sundial with EOT corrections for each
hour. The earliest example I've seen described is the vertical dial by
Père Ildephonse at the Convent Cimiez-Sur-Nice (the illustration is
from Cousins' _Sundials_ which dates from c. 1876. Is this the
earliest example of such a dial? And, again: does it have a unique name?
best wishes,
Peter
