A constellation representing the river
Jordan, introduced by the Dutchman Petrus Plancius on his
celestial globe of 1612. Jordan had its source near the tail of
the Great Bear in what is now the constellation of Canes
Venatici. The German astronomer Jacob Bartsch said in his Usus Astronomicus of
1624 that it had two sources, Jor and Dan, and that is how it
was shown on some charts – although not, strangely,
Bartsch’s own. From there it flowed between the Bear and
Leo (an area now occupied by Leo Minor and Lynx) and ended near
the head of the Bear next to Camelopardalis, another Plancius
invention. Jordanus was not shown by Bode.
