			Jordanus was introduced into celestial maps in early modern Europe, as it was regarded by central Europeans as a place far away that is still known to everybody - a projection of an utopia to a place that really exists, although ordinary people did not travel a lot and haven't ever visited it. Together with the constellations of [[Euphrates]] and [[Tigris]], it was projected into the sky as a reprise of Plancius's (older) "Biblical Maps" of the world.<gallery>
