Dear friends,
I need your help: I'm preparaing a lesson around the mesaurement of
time. I wolud like to know how old is the first equal hours sundial.Rohr
claimed that the "Man with the sundial" in the Cathedral of Strasbourg
is the earliest modern sundial and it dates from 1493. What is your
opinion? Can you indicate me some books on the subject?
Thank you and a lot of greetings. Piero Ranfagni
