Day 64: Time by Missy

time

the girls and i traveled all the way to longwood gardens just for this shot...
this is part of an analemmatic sundial, which was finished in 1939, after 8 long years of construction in order to accurately record the position of the sun and shadow cast by the 'gnomon'... the staff adjust the gnomon daily to match up with day and month markings on the analemma, which is two figure 8 curves for both the a.m. and the p.m.... the shadow line cast corresponds with large bronze roman numerals surrounding the sundial representing the hour... there are even minute markings between the numerals... it is extremely accurate.
i wish i could've gotten way high to show how the whole thing works, but it's just too grand.
