Mythology and History
The constellation was introduced in 1690 by the Gdańsk astronomer Johannes Hevelius in his work Prodromus astronomiae. For centuries it was considered part of Ursa Maior. It depicts the two dogs, Asterion and Chara, the bear guardian, who drive the bear around the celestial pole. [7, 51]
The brighter of the two striking stars is called Cor Caroli (Heart of Karl). According to folklore, the star was named by Edmund Halley in honor of King Charles II of England. It is said that the star shone particularly splendidly on the evening of the king's return to London in May 1660. Others claim that the original name was Cor Caroli Regis Martyris, in honor of Charles I, who was executed many years earlier. [88]
