Jordanus (the Jordan River) was a constellation introduced in 1612 (or 1613) on a globe by Petrus Plancius and first shown in print by Jakob Bartsch in his book Usus Astronomicus Planisphaerii Stellati (1624).
One end lay in the present-day Canes Venatici and then it flowed through the areas now occupied by Leo Minor and Lynx, ending near Camelopardalis.[1] This constellation was not adopted in the atlases of Johann Bode and fell into disuse.
