Many of the writers of the Middle Ages place the onyx under the signs Cancer and Capricorn and there is no reason to oppose them. The onyx of Cancer is white and light-coloured whilst that of Capricorn is black, the birth of the child is white and bright, and with black and sombre colours those on earth mourn for the earth loss of the departed. So the “coming in” and the “going out” symbolized by the two stones of onyx set in gold, the metal of the Sun, in true talismanic style was the memorial to the children of Israel, as it is to the world’s children forever. Phillips, an author of the middle 17th century, notes an old belief that the onyx is the congealed juice of a tree called Onycha, which is commanded to be used in a sacred way in the 34th verse of the 30th chapter of Exodus, and which Emanuel Swedenborg corresponds to “interior natural truth.” The statement, then, that the onyx is the congealed juice of the onycha is but a cryptic way of expressing the congealing of the waters of generation—a method followed by the occult masters through the ages. Old Rabbi Benoni sees in the onyx a bound spirit which, wakeful by night only, disturbs the wearer in sleep, and the master Ragiel in his “Book of Wings” recommends that a camel’s head or the heads of two goats among myrtles be cut on an onyx to control and constrain demons and to make the wearer see the terrors of the night during sleeping hours. This refers to the dark or Saturnine onyx which is also recommended to be enclosed in a setting of lead (metal of Saturn) and engraved with the figure of a king crowned or a witch seated on a dragon especially in the practice of dark or doubtful occult things. Certain varieties of onyx presenting the appearance of an eye were largely employed as eye stones and it was recommended that such specimens be lightly rubbed over the closed eyelids after work wherein the eyes have been employed. Leonardus of the 16th century says that this onyx enters the eye of its own accord and if it find anything within that is noxious it drives it out and tempers the hurtful and contrary humours. As a higher Saturnine stone the onyx aids spiritual inspirations and helps the wearer to restrain excessive passion. In the writer’s book on “Zodiacal Symbology and its Planetary Power” the first degree of the sign Cancer is symbolized as “a curious ring set with a large heart of white onyx.” The 1st, 2nd, 10th, 11th, 12th, 28th, 29th degrees of Cancer are much influenced by the planet Venus and to these degrees especially applied the white onyx engraved with a figure of Venus, a charm recommended by old masters as a talisman of beauty and strength. It was considered ideal for a baby girl born under those degrees of Cancer according to astro-philosophy. Mr. King mentions a beautifully executed onyx intaglio showing Castor naked, in his hand a large broadsword, weeping over the tomb of Aphareus. The onyx in this case would be of a more sombre hue and would be classed amongst the
