Darken, Surrey, England — February 1661
Flying cathedrals
A “discreet sober gentleman” saw a strange cloud in the evening sky, and two objects he compares to cathedrals or churches, “having upon it diverse goodly Pinnacles, and each of them a long streamer flying upwards upon it, and as he beheld it, he thought it grew up to a greater splendor and glory.” The other object was darker. After a while, the large one emitted puffs of vapor and disappeared, while the smaller one grew and became brighter. The witness was called into his house and could not observe the end of the phenomenon.
