I’ve said recently that the symbol )O( actually invokes the Dark Moon, or the Void-in-Course Moon, rather than the Full Moon. That’s because the Dark Moon is the one which occurs between the waning and waxing crescents.
So, look at the Moon — if the curve of the moon fits into your cupped right hand, it’s waxing; and if the curve of the moon fits into your cupped left hand, it’s waning. A few months of direct observation will show this to be true.
The “nine phases” of the Moon can be used as celebrations of the Nine Muses, or you can use Chris Warnock’s book, “The Mansions of the Moon” to learn the angels of the Twenty-Eight Mansions, which are really powerful. Either method will teach you a huge amount of astronomy and astrology.
Here’s what I learned on this image: it’s difficult to ‘erase’ watercolor, even digital watercolor. I thought that by putting the watercolor on second, after the green ground, that I’d then be able to erase it and lay down the figures of the dragon and the knight. Doesn’t work that way. I should have sketched the figures first, worked the green ground around those figures’ legs, watercolored or markered the sky into place, and then drawn and colored the figures. But hey… Draw and learn. You can’t expect to be perfect right away. You have to make excellent mistakes and then see through the mistakes to the key lessons you’re trying to learn. No one starts as a perfect artist — the key is just to make the art and learn the lessons it’s trying to teach you on the way.
