So following up on yesterday’s entry about the armillary sphere on the Vatican News Services website. Today I read about the armillary spheres used by Tycho Brahe and was honestly quite stunned. He had 4 different armillary spheres! Above is my favorite, the Great Equatorial Armillary Sphere, which looks quite a bit like the hexagon quilt projection.
Check out the others:

Holy See an Armillary Sphere?
Looks like there is an Armillary Sphere in the background. I find this interesting simply because an Armillary Sphere most likely has a pagan Zodiac on it. Two months ago I made those Astro-theological overlays (which included the Vatican) and today I stumbled on to a slightly hidden one on the Holy See’s News Services webpage.

An updated Armillary Sphere
Above is an Armillary Sphere, which was used in ancient times as a celestial calendar. Created prior to the orrey, which is a helio-centric model, the Armillary Sphere allowed it’s user to know where the moon was in relation to the earth. It also featured a zodiac, which I’ve been playing with earlier this year.
To make the above image, I edited the public domain engraving on the Wikipedia page and added a very tiny NASA Blue Marble satellite image of the western hemisphere of the earth. I am probably going to add this image to this website’s splash page, which will knock the total number of visual combinations to over 3,000! I’d like to make a few more first. The U.S. Naval Observatory’s logo gave me some ideas :-).
Since May I’ve been very interested in old maps and the scientific instruments that were used. When I discovered Julius Schiller, who published Coelum Stellatum Christianum (which replaced pagan constellations with biblical and early Christian figures), I began to take quite an interest in celestial cartography.
Around that same time my next door neighbor, thinking that my cartographic expertise had to do with astronomy, offered to let me borrow his children’s telescope. Since then (about mid-August) I’ve been looking to the night sky about once a week; much to my enjoyment. Last week was a highlight because we met on the rooftop and set up the telescope. I showed him and his kids how to use the telescope and was able to show them the moon for the first time. DC has quite a bit of light pollution which makes celestial observances quite tough. The neighborhood watch was even in effect because my housemate said people from the street over knocked on our door warning her about people on the roof.
My favorite night sites are Venus and the Moon, simply because they are the easiest to find. I really want to see Mars, Saturn, or Jupiter. But I’ll just have to wait until the night’s right (or I have ample patience). Ironically, a week after my neighbor brought over the telescope, the new version of Google Earth came out with an integrated celestial viewer.
I have more to write about my nightly observations and research I’ve been dabbling in at a later date.
