Prophets and discoverers, painters and poets, all share this amphibial quality of living both on the contoured drylands and in the boundless ocean. In the history of the race as of the individual, both branches of the cosmic quest originate in the same source. The priests were the first astronomers; the medicine-men were both prophets and physicians; the techniques of hunting, fishing, sowing, and reaping were imbued with religious magic and ritual. There was division of labour and diversity of method in the symbols and techniques, but unity of motive and purpose.
