	<description>I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.</description>

		<description>You bunch of heathens! It looks like the Virgin Mary.
The God of Justice and Mercy is going to send you all to Hell for not seeing this right off!</description>

		<description>Argyl -- yes, a lot of the things held by some (not all!) neopagans to be ancient texts, rituals, beliefs, etc. are not actually ancient.  If you trace them they usually go back to Robert Graves, Gerald Gardner, Madame Blavatsky, or Eliphas Levi.

I heard somewhere (great source, that!) that there are people who think the Necronomicon was a real book.  Somebody apparently put a fake ad for a copy into a bibliographic journal and was swamped with offers.</description>

		<description>If there is no term like areology for Mercury, I'd like to suggest hermology, in keeping with areology, geology, etc. That is, greek based words for the study of land formations. (Mars - Ares, Mercury - Hermes.)

I think hermetology and hermetiscism and such have already been taken long ago for alchemical pseudosciences, after Hermes Trismegistus, some sort of mythical Greek alchemist and "god of secret wisdom" like Imhotep in Ancient Egypt. I think though that both are based on Hermes (the god after which Mercury was named in Greek) and Thoth (the god of wisdom and scribes in ancient Egypt). Indeed the 42 Books of Thoth seem to be ones of the most sought after items by magick believers today.

For some reason the priests of ancient Egypt never preserved any of these purported books, and while 5000 year old writings of their religious beliefs have been unearthed,  there's no written evidence about these 42 books until the late 19th century when ancient Egypt became a fashionable thing to write about.</description>

		<description>I've thought that it must be such. But when viewing other "illusions", like the cube drawn with lines it's easy to switch between seeing it either way. I'm always disturbed that I need to flip a picture around to see what it actually represents... sort of makes me like laser and radar measurements more that photographs, since the data can be represented unambigously.

When I've seen the photos with the light from the "right" direction, I can understand the craters, and in this case Mercury more, the illusion of pancakes is really annoying. Of course most images are published with north at top, at least I think that's the case? Also the illusion of the phone handset is less prominent when you see it with the topography right. It's a depression and a central peak that might have formed from a low angle impact.

I don't think the amount of double craters so far seen in pictures is a coincidence. Of course, I'm just an amateur, what do I know about planetary geology. There's a term for martian geology, Areology. What's the term for Mercurean geology? Hermology?</description>

		<description>Argyl: It's a psychological effect. We're used to seeing things lit from above, since that's where the sun is and where generally you have the room lights. So if you see an aerial photo of a crater, and the sun is off the top of the frame, you see it as a crater. Your brain interprets the shadow at top and the highlight at the bottom correctly.

But if the sun is off the bottom of the frame, your brain interprets the highlight at the top to be a bump, a reflection from the sun off the top of the frame, and the shadow at the bottom to be a shadow off of what your brain is now interpreting as a hill.</description>

		<description>Why is it that every planetary image I see where the sun shines from the right or bottom, the craters look like pancakes sticking out? I always need to flip those images 180 degrees to to see the topography correctly.</description>
