Der Rütli (or: Das Rütli, Rytly, or Rytli) was a German literary group, named after the famous Swiss meadow.
It was founded on 9 December 1852 by members of the Tunnel über der Spree as "a kind of subsidiary tunnel" ("eine Art Nebentunnel" — Theodor Fontane) with a more intimate atmosphere, in contrast to the ceremonial and public nature of the larger group's activities.
One major difference between meetings of the Tunnel and meetings of the Rütli was that members' wives were admitted, albeit only after the "work" of the gathering was completed.
The group entertained many guests like Berthold Auerbach, Friedrich von Bodenstedt, Eduard Devrient and others.
By 1892, only three members still attended meetings; on 5 January 1897 Fontane wrote to Lazarus that "the Rütli's current slumber is a blessing; for years it's been in a tragic way."
