During the Renaissance, the su was regarded primarily as a source of light which gave form to all things*; during the Enlightenment, paradoxically, the sun was regarded primarily as a source of heat. Paracelsian chemistry of the 1500s introduced salt as a third principle which embodied the other two, mercury and sulphur; salt was that universal mediating presence which represented earth. By the late 1700s salt was no longer a metaphysical principle but an acid-base compound, and volatile salts aroused most interest. These changes in scientific perceptions of sun and salt ran parallel to one another: beginning as transcendent sources of form, sun and salt came to be considered manipulable sources of energy. Our r-;odern approach to energy derives from a period during which Europeans gradually lost their belief in the creative agency of two essentials to human life.

11 In the English language, one used a feminine pronoun in reference to the sun until the end of the sixteenth century; after that the sun was masculine. In alchemy and in Glauber's chemistry, salt was feminine, representing the anima mundi (world soul); later, salt was neuter. This transformation in the sexuality of sun and salt comes just as the two are losing metaphysical potency; one might suggest, à la Jung, that the splitting away of the feminine from both sun and salt was either the cause or the sign of their loss of transcendent status.

Several papers presented at the Helios Conference tempt me to exclude colonial New England from my generalization about the declining imoortance of sunlight vis-a-vis the sun's heat. Helen H. Naugle and Peter J. McGuire show that American Puritans had need of a bright and nourishing sun in their response to the New England wilderness, itself a New Jerusalem apart from the scorching sun of English Puritanism. Keith R. Burich shows the high value olaced on sunlight by Jonathan Edwards.

Until 1900, Memoirs of the American Philosophical Society, 44 (Philadelphia: American Philosophical Society, 1957). Robert Hooke, seeking to explain the mechanism of memory, would postulate the existence in the brain of a substance similar to phosphorus, which seemed to be able to receive and retain light in much the same manner that humans retain impressions. Hooke also used an analogy to the sun, but it was to the sun's radiation, which is felt more powerfully the closer the sun is. See the fine article by B.R. Singer, "Robert Hooke on Memory, Association and Time Perception;" Notes and Records of the Royal Society of London, 31 (July, 1976), 115-31.
