For in June, 1692, I saw by reflexion in a vessel of stagnating water three halos, crowns, or rings of colours about the Sun, like three little rainbows, concentric to his body. The colours of the first or innermost crown were blue next the Sun, red without, and white in the middle between the blue and red. Those of the second crown were purple and blue within, and pale red without, and green in the middle. And those of the third were pale blue within, and pale red without; these crowns enclosed one another immediately, so that their colours proceeded in this continual order from the Sun outward: blue, white, red; purple, blue, green, pale yellow and red; pale blue, pale red … like crowns appear sometimes about the Moon.
