Lunar and solar eclipses are profound events for those who witness them. For thousands of years, people have observed and interpreted these phenomena. For some, solar eclipses were terrifying events. For others, a lunar eclipse could signify a time of healing. For plant and animals, the darkening of the sun may signal that it is time to prepare for night. However you interpret an eclipse, it is something to remember.
