Boat of the Sun
Boat of the Sun. This sacred solar boat was called Sekti, and it was steered by the dead. With the Egyptians the highest exaltation of the Sun was in Aries and the depression in Libya. (See “Pharaoh”, the “Son of the Sun”.) A blue light—which is the “Sun’s Son”—is seen streaming from the bark. The ancient Egyptians taught that the real colour of the Sun was blue, and Macrobius also states that his colour is of a pure blue before he reaches the horizon and after he disappears below. It is curious to note in this relation the fact that it is only since 1881 that physicists and astronomers discovered that “our Sun is really blue”. Professor Langley devoted many years to ascertaining the fact. Helped in this by the magnificent scientific apparatus of physical science, he has succeeded finally in proving that the apparent yellow-orange colour of the Sun is due only to the effect of absorption exerted by its atmosphere of vapours, chiefly metallic; but that in sober truth and reality, it is not “a white Sun but a blue one”, i.e., something which the Egyptian priests had discovered without any known scientific instruments, many thousands of years ago!
