Re: Does this type of dial have a name?

2021-08-16 Thread Steve Lelievre 

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,

Re: Does this type of dial have a name?

2021-08-16 Thread Willy Leenders 
ANALEMMA is derived from the Greek ANA (above) and LEMMA (survey) and thus 
means 'survey from above' or ‘projection'. If you look at a large equatorial 
sundial (hoop sundial) from above, you see the elliptical pattern of an 
analemmatic sundial.

The figure-eight projection of the graphical representation of the equation of 
time also corresponds to that Greek name. Hence the confusion. An analemmatic 
sundial has nothing to do with the graphical representation of the equation of 
time.

Hi Peter,

A descriptive name which is sometimes attached to dials like this is 
'analemmic', i.e. it has analemmas instead of hour lines but it is not 
an analemmatic dial.
