Madrid, Spain: Unexplained black cloud — 4 May 1641
At 9:00 P.M., “the sky being very calm, without there being a single cloud in it, (Jose
Pellicer reported) an extremely black and dark cloud, that approached from somewhere between the east and the north, dilated and narrow, crossing between the west and Midday, that was stationary for some time” - giving the impression that Pellicer may have seen something resembling the ‘cloud cigars’ dealt with in modern reports. Pellicer goes on to mention a burst of sound of unknown origin in the sky over Molina de Aragon. The people there heard “loud noises, bugles, drums, as if an invisible ferocious battle were happening but without anything to be seen.”
