Itzpapalotl, 1900s

In Aztec myth, Itzpapalotl (“Clawed Butterfly”/”Obsidian Butterfly”) was a fearsome skeletal warrior goddess. She rules over Tamoanchan, the paradise of victims of infant mortality, the place where humans are created. As the mother of Mixcoatl, she could appear in the form of a beautiful, seductive woman or terrible goddess with a skeletal head and butterfly wings made of stone blades. Below is a Dancer in Paris, 1900s which could be used as a possible representation of Itzpapalotl

Vancouver UFO, 1937

Using a tripod to shoot Christmas lights at city hall, Leonard & Wilfred Lamoureux got an unexpected surprise

The two were suddenly astounded to see a “bright bright blue light” drop straight down from the sky. It became larger as it did and so they were able to observe the source of the light as an object that Leonard described as “two saucers” open ends facing each other, glowing bright blue. The object then moved “dead straight” horizontally across the sky. When it just appeared to clear the flagpole on the roof of the City Hall it came to an almost dead stop and Leonard clicked the shutter on the camera. The object then shot straight back up into the sky. “They never seen anything fly so fast!” This scared them to death and they ran from the scene. The object made no sound.
