As Professor Joad used to say, it all depends what you mean by ‘direction’. A
shadow simply falls on a surface. It doesn’t have a direction.

So . . . what is the explanation? From the angle of the tracks it looks
quite far north (or south). Can the curvature of the soup can do it? I

You are right, the dial dates from 1700. The church was destroyed and rebuilt

Thanks for pointing this out. It is a nice dial - No 900 in the BSS

If you print a copy of the picture, you can see that the style does at least
pass through the line 6 - 18 and 12 - 24, so that is OK. I can't check the

could be that (to the horizontal). As a fairly

Saxon dials have only been found, as far as I know, on church or monastery
buildings. This is understandable as their design was to show the tides, for
governing church offices. But is there any evidence that they could also have
been used on domestic buildings? If so, like the buildings
You have to think of the line of sight from the sun to your eye as a lever,
with the fulcrum being the horizon. As you run upstairs, the fulcrum moves
further away, and so your end of the lever gets longer and moves faster. Is

I have been asked for an opinion on the item illustrated here, and would

This correspondence reminds me of unreadable dials I have encountered and
wondered about, though on a far smaller scale. For example SRNO 1958 at
Weston, Notts, is a nice horizontal of 1694, but it is mounted on a pillar

It main interest lies in its supporters, having above an elaborate winged

This figure, and more
