For reasons wholely unkown to yours truly, few people speak, or write, of the Mechanick Dyalling chapter of The Doctrine Of Handy-Works. If you put your mind to it, Joseph Moxon was known for his skill in making scientific and philosphical appartti of this very sort.
For that matter, us moderns seem to focus on the hand tools sections of Handy-Works, seemingly overlooking the overall import of the book as being an introduction to the building of a house. Sure, there are some very swift and nifty phrasings of various obscure and scure tools but if you take the time to delve into the makings of the building itself, you'll find just as much obscure and interesting information.
Trust me, I've read it way too many times during proof readings and am doing so again.
Back to Dyalling. The final chapter is devoted to the making of sun dials, or, as those sexy 17th century guys liked to say, Sun Dyalling.
Here are three nearly raw scan samples from Sun Dyalling. No touch up yet, no adjustments of any sort other than a minor bit of edge trimming for the blog post. If I was one to understand the mathematics behind the creation of a sun dial, I would make one.
Being somewhat two left footed (no offense to the sinister of the world), I also have a book entitled which provides some additional information on how to create a ready to wear sun dial: The Timepiece of Shadows : a History of The Sun Dial by Henry Spencer Spackman; New York : W.T. Comstock, 1895.
The sun is finally out and perhaps, just perhaps, a Sun Dyal will grace the grass this year.
Till next, Gary
