It is this information, in fact, that helps establish who came up with constellations in the first place; these astronomical artisans could not have lived further north than about 36 degrees North latitude based on the reach of the celestial atlas they concocted (that is, there were no constellations near the south celestial pole despite the presence of stars there). For another, Orion has a highly distinctive shape, and unlike many other constellations, it arguably resembles the thing it was named for – a hunter. Lindell worked in greyhound racing for 25 years.
