The story of Noah and his ark is a cosmic allegory concerning the repopulation of planets at the beginning of each world period.
Several authors have attempted to prove that Isis, Osiris, Typhon, Nephthys, and Aroueris (Thoth, or Mercury) were grandchildren of the great Jewish patriarch Noah by his son Ham. But as the story of Noah and his ark is a cosmic allegory concerning the repopulation of planets at the beginning of each world period, this only makes it less likely that they were historical personages. According to Robert Fludd, the sun has three properties — life, light, and heat. These three vivify and vitalize the three worlds — spiritual, intellectual, and material. Therefore, it is said "from one light, three lights", i.e. the first three Master Masons. In all probability, Osiris represents the third, or material, aspect of solar activity, which by its beneficent influences vitalizes and enlivens the flora and fauna of the earth. Osiris is not the sun, but the sun is symbolic of the vital principle of Nature, which the ancients knew as Osiris. His symbol, therefore, was an opened eye, in honor of the Great Eye of the universe, the sun. Opposed to the active, radiant principle of impregnating fire, hear, and motion was the passive, receptive principle of Nature.
