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.
When the Moon and lord of the ascendant shall be impedited by the lord of the 8th, the sick person hath cause to fear. - William Lilly (1602.-1681.)
