Hi Bill (and other dialling colleagues),
The data that you show looks very similar to the Venerable Bede's shadow length
tables (though the values are slightly different). This gives the length of a
person's shadow on the assumption that their height is equal to six of their
own feet (tall
I had exactly the same thought as John-that this was a table of shadow lengths
in the form that Bede gives in the 7th century.

Dear Friends
Don't forget the beautiful Missal of St Leofric 10-11th Century for an elegant
but simple shadow length table
see

Does anyone know if Bede's Table is available in manuscript image form
Dear Brent,
You ask a fascinating set of questions.
Has the leap year problem been solved with
solar calendars?
At one level, the problem is intractable. You
get defeated by the calendar bequeathed to us
by Pope Gregory XIII...
The problem is that the Gregorian calendar is
hardly an
Dear Brent,
Slight goof. In step 7 I meant to say:
7. Keep going until 12 noon on 29 February
next year. You will have drawn EXACTLY
366 little lines. [Note that 29 February
is 365 days AFTER 1 March the previous
year, not 366 days.]
You have 366 lines and 365 normal
Dear Andrew,
Thank you for your two messages, sent off-list but my
response may be of trifling interest to others...
It is true that 128 tropical years is very close
to 46751 days but when it comes to a real solar
calendar (one you can look at and say Oh, I see
that today is 9 March) I regard
All,
I am trying to find a YouTube video that was linked to from this list
several years ago.
It shows a large analemmatic sundial located in a public park in Moscow (I
think). Various passersby tried to figure out how it worked, where to
stand, etc., and it was pretty funny. This could not

Hi Reinhold,
Yes, thats it!! Many thanks.
When it was first posted, I remember a comment by someone on this list:
Most of the people stood on the label of the month, rather than on the
point on the centerline to which the label referred. (Im not sure what
point the pigeons went to.)
Loved the human dial video!
I sent the video link to a client in Michigan who is ordering a human
sundial design. She thought it was fantastic. It will be a great selling
tool for potential clients!
Thx so much!
John
p.s. BTW, We are featuring Alek Boldyrevs stained glass sundial
Hi Frank;
Thank you for that detailed response.

Do their rocks still show where the solstices will occur now?
Your explanation below seems to indicate that their
