PIX4591661: Constellations of Grus and Piscis Austrinus - The Crane is a constellation in the southern hemisphere, located just below the Southern Fish. Grus (the Crane) is meant to represent a water bird, which may be a crane or perhaps a flamingo. This stellar grouping was introduced by Johann Bayer in his star atlas of 1603. Because of its location in the southern sky it is not visible from north latitudes above 40 degrees. Even if it were visible, it would hardly be remarked upon. Piscis Austrinus (the Southern Fish) once included Grus, and nowadays represents the Southern Fish, drinking from the water poured by Aquarius, adjoining it to the north. Piscis Austrinus was one of Ptolemy's 48 constellations and its brightest star is Fomalhaut, a name drived from the English for fish's mouth / Bridgeman Images

PIX4591695: Constellation of Hercules - Constellation of Hercules - Constellation of Hercules and Boreal Crown. On the left, the bright star is Vega de la Lyre. Hercules, the Roman Hero, is best known for his twelve labours, mentioned throughout the Greek constellation legends as Herakles, who is sometimes identified with the much older (5000 BC) Sumerian strong man Gilgamesh. To the Greeks he was the son of Zeus and the earthly queen Alkmene. Zeus' goddess wife Hera was not best pleased and sought to destroy Herakles. Later he was to accomplish eight heroic acts as well as his famous 12 labours, these last perhaps representing the Sun's passage through the zodiacal constellations. The constellation is the fifth largest in the sky but does not catch the eye and has no bright stars rivaling Vega in adjoining Lyra or even the much fainter Gemma in Corona Borealis to the west. However, there are many interesting double stars in Hercules as well as the northern hemisphere's finest globular cluster M13 / Bridgeman Images

It was created by Johann Bayer and appeared in his atlas of 1603. The reference to the American Indian comes from the constellation engraving by Bayer, which shows a figure carrying arrows; however, even if it was conspicuous, most of the constellation is invisible from the USA / Bridgeman Images
