KPOE’s
In 1922, the International Astronomical Union standardized 88 constellations. 48 classics from Greek mythology where “cropped” and 40 “no story” additions were added:
14 named by Dutch sailors exploring southern seas 3 ship parts and 12 tools / inventions 1 lizard, 2 dogs, and 2 cats to “fill the gaps”

KPOE’s
Why? - Reduced size made them better reference points - Boundaries were drawn (1930)- Sky became like jigsaw puzzle
Why Learn & Interpret pre-1930 sky? - Coordinate system (RA & Dec.) used universally- Originals look better
