Grus, “The Crane”, is one of the inventions of Pieter Dirkszoon Keyser and Frederick de Houtman, two Dutch navigators who observed the southern skies at the end of the sixteenth century. It is another of their creations based on animals. The crane was also considered a symbol of astronomy to the ancient Egyptians.
