Illustration of the constellation of Taurus. Taurus is the second sign of the Zodiac. The constellation is depicted as a bull charging at the shield of Orion, below the Bull to his left. The Sun is in Taurus between 20 April and 20 May. It is a conspicuous and important constellation, and has been depicted as a bull for many centuries. The bright star Aldebaran marks the lower of the Bulls eyes. The Suns path, the ecliptic, is the black and red line at centre. Illustration is based on a sky map by the Polish-German astronomer Johannes Hevelius (1611-1687), published posthumously in 1690.
