exceptionally, a three-headed eagle (or rather, an eagle with two additional heads mounted on the tips of its wings) is shown as the coat of arms of minnesinger reinmar von zweter (c. 1200–1248) in the codex manesse (c. 1300). an unrelated depiction of the "reichsadler" with three heads is found in the "wappenbuch" of conrad grünenberg (1483). a three-headed bird (not necessarily an eagle) is also found in the middle low german illustrated manuscript "splendor solis", dated to the 1530s.
