	Ian Ridpath<ref name=":0" /> elaborates: <blockquote>Also known as Jordanus Fluvius or Jordanis, this constellation representing the river Jordan was introduced by the Dutch cartographer Petrus Plancius on his celestial globe of 1612. It incorporated eight ‘unformed’ stars that Ptolemy had listed in the ''Almagest'' as lying outside the figure of Ursa Major. These stars are the modern Alpha and Beta Canes Venatici, Alpha, 31, and 38 Lyncis, and three others of uncertain identity. On his globe he depicted the river as flowing from two fountains named Ior and Dan. </blockquote>There is a striking similarity between Plancius's drawing of Jordan with its two sources on the globe and in his Biblical Maps (1590): <gallery>		Ian Ridpath<ref name=":0" /> elaborates: <blockquote>Also known as Jordanus Fluvius or Jordanis, this constellation representing the river Jordan was introduced by the Dutch cartographer Petrus Plancius on his celestial globe of 1612.

One that did was by Bartsch’s mentor Isaac Habrecht (1589–1633) in 1628, illustrated below. Habrecht had previously included Jordanus and several other new Plancius constellations on a globe of 1621, from which Bartsch first learned of them. </blockquote>[[File:Bartsch1624 Iordanis.png\|frameless\|855x855px]]

Cf. George Adam Smith, ''The Historical Geography of the Holy Land, Especially in Relation to the History of Israel and of the Early Church'' (New York: A.C. Armstrong and Son, 1895), p. 472 [note 1] [[https://archive.org/details/historicalgeogra1895smit/page/n503/mode/1up Internet Archive link]].</ref> Thus, it is proposed to name one, two or all three stars within the obsolete constellation (NOTE: WGSN does not assign single names to pairs of stars, so select a single star per name):

	# α Lyncis: "Jordanus", ([https://simbad.cds.unistra.fr/simbad/sim-basic?Ident=alpha+Lyn&submit=SIMBAD+search SIMBAD]: 3.1 mag in V)		# α Lyncis: "Jordanus", ([https://simbad.cds.unistra.fr/simbad/sim-basic?Ident=alpha+Lyn&submit=SIMBAD+search SIMBAD]: 3.1 mag in V)
	# 25 CVn: "Ior" ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=25+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.82 mag) for the sake of symmetry, perhaps ~~also~~ BH CVn ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=BH+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.94-5.1 mag [https://www.aavso.org/vsx/index.php?view=detail.top&oid=5103 VSX]), but on some maps explicitly only one star here		# 25 CVn: "Ior" ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=25+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.82 mag) for the sake of symmetry, or perhaps BH CVn ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=BH+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.94-5.1 mag [https://www.aavso.org/vsx/index.php?view=detail.top&oid=5103 VSX]), but on some maps explicitly only one star here
	# 20 CVn + HR 4997: "Dan" ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=20+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.69 mag, [https://simbad.cds.unistra.fr/simbad/sim-id?Ident=HR+4997&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.94 mag)		# 20 CVn or HR 4997: "Dan" ([https://simbad.cds.unistra.fr/simbad/sim-id?Ident=20+CVn&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.69 mag, [https://simbad.cds.unistra.fr/simbad/sim-id?Ident=HR+4997&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id SIMBAD] 4.94 mag)

	The above list of historical names confirms, that there are no Arabic names competing for the stars are suggested to call Ior and Dan.		The above list of historical names confirms, that there are no Arabic names competing for the stars are suggested to call Ior and Dan.
