But later than Druidical times, Arabian wisdom made the southwestern portion of the European continent brilliant with learning, during the long period of the Christian dark ages, a time when, like the Bourbons of later date, Christians learned nothing, a time when no heresy arose because no thought was allowed, when there was no progress because there was no doubt. From these countrymen of the Queen of Sheba, the Spanish Arabs, Columbus first learned of a world beyond the Pillars of Hercules. Architecture rose to its height in the beautiful Alhambra, with its exquisite interlaced tracery in geometric design; medicine had its profound schools at various points; poetry numbered women among its most famous composers; the ballad originated there; and the modern literature of Europe was born from a woman's pen upon the hearth of the despised Ishmaelite, whose ancestral mother was known as Hagar, and whose most brilliant descendant was the Queen of Sheba. Nowhere upon the earth has there existed a race of improvisatores equal to the daughters of that despised bondwoman, the countrywoman of the Queen of Sheba. As storytellers the world has not their equal. Scherezade is a name upon the lips of Jews, of Gentiles, of Mohammedans and of Christians. A woman's "Thousand and One Nights" is famous as a combination of wit, wisdom and occultism wherever the language of civilization is spoken. With increasing knowledge we learn somewhat of the mysteries of the inner, higher life contained in those tales of genii, of rings and of lamps of wondrous and curious power. The race descended from Hagar, of which the Queen of Sheba is the most brilliant reminder, has given to the world the most of its profound literature, elegant poetry, art, science and occultism. Arabia is the mother of mathematics; from this country was borrowed our one (1) and our cipher (0), from which all other notation is evolved. Astronomy and astrology being among the oldest sciences, the moon early became known as "the Measurer," her varied motions, her influence upon the tides, her connection with the generative functions, all giving her a high place in the secret sciences. While in a planetary sense the Queen of Sheba has in a manner been identified with the moon, as Sabs, she was also connected with the sun, the same as Solomon and the serpent. When Moses lifted up the brazen serpent in the wilderness it was specifically a part of sun worship. The golden calf of Aaron was more closely connected with moon worship, although the serpentine path of both these bodies in the heavens identified each with the serpent.
