Constellation theory of the Great Serpent Mound

From Squier and Davis, Ancient Monuments of the Mississippi Valley (1848)

The yoke is at bottom right. A berm forms the oval head, in the middle of which is a capsule-shaped mound a few feet high.

We look for an arrangement of stars that is flopped horizontally from the Squier drawing, so the head in the sky is pointed westward like the image on the ground.

Winter constellations visible from Ohio.

Yellow oval is the head. Just below oval is a necklace of faint stars, forming the top of the yoke. The bright star in Canis Minor (Procyon) is just below and right of the bottom of the yoke. The coil of the tail encompasses Canis Major and the brightest star in Puppis (Naos).

The hourglass shape of Orion has a rough counterpart in the Fort Ancient earthwork, not far from Cincinnati.

The Bayeux tapestry (scene 32) shows amazed observers pointing at Halley’s comet above a tower. In the night skies of January–March 1066, the spraying “star” passed through the middle of the oval head at Gemini.
