I sort of like the Aztec engraving...of course, I have a tattoo of Quetzalcoatl in his guise as the Plumed Serpent, or Lord of the Air if you prefer, on the inside of my right wrist. Me, I always preferred Flying Dragon, hence the name of my corporate entity, Flying Dragon Ltd. There's an interesting story about me running into a Hopi medicine man out west...but hey, that's a story better related over beer. Quetzalcoatl wasn't a blood god, but I did toss him a silver dime with a drop of my blood on it last time I was on the Pyramid of the Sun outside of Puebla, Mexico. The Pyramid of the Sun is, of course, where Quetzalcoatl fled when he was deposed by the jaguar god Tezcatlipoca...but you all know that, right?
Anyway, I was on the Pyramid of the Sun at the spring equinox, so I found a really deep crevice up at the top, pricked my thumb, smeared an old silver dime I got in Mexico City with the blood and tossed it into the crevice, thanking Quetzalcoatl for my luck and extreme good fortune as the old Hopi had instructed me. The dime bounced once and disappeared...on cue, Popocatepetl Volcano, a few miles away, spewed a spectacular column of ash and smoke into the air. My Sweetie told me to quit messing with ancient gods...
