In the French bulletin "L'Astronomie" 1970 feb. p 83-86 L. Janin
writes about the oldest known analemmatic sundial near the church of
Brou (Bourg-en- Bresse) in France:
"His origine is from the time of the building of the church
(1506-1536). His function was to indicate the hour for the builders.
He has the form of an ellipse of 11 m 50 by 8 m 30.
On 24 stones the hour marks are engraved. On a stone of 3 m 85 by 90
cm in the middle of the ellipse a style is placed on the date."

Any advice on the history of this type of dial will be appreciated.
I have been contacted by a school project with the relatively simple
question, when did we start using the human as the gnomon?
Setting aside 'pre-history' is it the more recent past?
Regards, Doug
