Long tables can be located in the politics of congregation by looking at one occasion when Danish furniture designer Piet Hein tried to intervene in peace negotiations after the Vietnam War.
Hein contacted the parties after he heard a rumour that the delegates could not continue because they were in dispute about the shape of the table. He offered his design—the super-elliptical table—believing that the elongated circle would quell hierarchies suggested in a rectangle, or avoid the overt utopianism of a round table. Shortly after, negotiations started up again, not around Hein’s table, but likely after the diplomats abandoned the shape of the table as the foremost pressing subject—though pressing enough to summon a hiatus on political arbitration.
