Ruby takes its name from the deep red gemstone, historically prized and often linked with passion and vitality rather than cool detachment. The name is commonly read as carrying warmth and intensity -- a presence that's felt rather than merely observed, valued for its depth of color as much as its rarity.
The astrologer is able to control the actions of the stars if he knows the influx of their nature; is quite likely that he can modify the action before it happens. - Ptolomeus
