Today there are 88 official constellations. Now in the ancient world of the Mediterranean and Middle East, there were less than sixty constellations, owing partly to a lack of knowledge of stars to the south that were never seen from those latitudes. There are (and were) a great deal more unofficial star patterns, called asterisms. In order to be a constellation, everybody has to agree that that’s what it is. An asterism is more personal, and usually a lot easier to see or imagine. So the Great Bear, Ursa Major, includes the stars of the Big Dipper (what we call it here in America,) or the Plough (England,) or the Chariot (ancient Rome.) Cygnus the Swan becomes the Northern Cross, Scorpius becomes the Fish Hook, and Sagittarius the Archer looks like the crude outline of a teapot. When you first start to trace out the constellations, these asterisms will help make the more complex patterns easier to learn.
