For the number 7, as we all know, the ancient Hebrews had a singular fondness, attributing to it a magic potency. This may have arisen from the traditional story of the seven days of Creation, and the institution of the Sabbath--without a doubt the most important of Hebrew institutions. This certainly enhanced the reverence for the number 7, which soon became the most sacred Hebrew number, bearing nearly always the connotation of holiness and sanctity or mystic perfection. The acts of atonement and purification were accompanied by a sevenfold sprinkling. There were seven trumpets, seven priests that sounded them seven days around Jericho, seven lamps, seven seals, etc. The seventh day was the Sabbath, the seventh year was the Sabbatical (still observed to the well-earned emolument of our professors in the Universities), and seven times seven years brought on the Jubilee. The seventh month was the holiest month of the year (which we appreciate now by regarding September as an auspicious month in which to return to college studies). The number seven soon came to be used also conventionally as an indefinite or round number, indicating abundance, completeness, perfection.[1] Cicero calls seven the knot and cement of all things, as being that by which the natural and spiritual world are comprehended in one idea. _The Manifold Symbolism of the Seven Lamps_ BE that as it may, our ancestral learned men seem to have found no end of significant meanings in the seven lamps of the Menorah. Generally it was held to represent the creation of the universe in seven days, the center light symbolizing the Sabbath. Again, the seven branches are the seven continents of the earth and the seven heavens, guided by the light of God. According to Philo and others, the seven lights represent the seven planets which, regarded as the eyes of God, behold everything.[2] The light in the center, which is especially distinguished, would signify the sun, as the chief of the planets. With this was combined the mystic conception of a celestial tree, with leaves reaching to the sky and fruit typifying the planets. There would be little difficulty, of course, in extending this symbolistic catalogue ad infinitum. We could easily and perhaps profitably select Seven Wonders of Hebraic history or achievement, seven great epochs in the development of Hebraic culture, seven great leaders of the race, etc. We might also say that the seven lights represent the seven chief studies which make up a liberal education--the Trivium and Quadrivium of the Middle Ages, substantially the foundation of the university curriculum of today[3].
