Oh, yes, to bring to you the wonders and mystery and secrets of alchemy . . First, we'll start with the pentacle that you see here on the floor of my lab. The four elements, fire, air, earth, and water, have their own symbols. Air is represented by the circle, fire by the triangle, earth by the square, and water by the crescent - all points on the alchemist's pentacle. You have probably seen one in Rycharde's and Edmonde's lab .
Air is moist and hot.
Fire, naturally, is hot and dry. Earth is dry and cold. And finally, water is cold and moist. In addition, the art of astronomy is quite closely related to alchemy. A very clear example of that are the seven basic metals.
