Cotatre, Cotovatre, Scottewatre
The town, and possibly a lake, of the smith Trebuchet in Chrétien de Troyes’s Perceval. Perceval had to travel there to repair the Grail Sword.
It becomes a castle in the Fourth Continuation of Perceval and a kingdom in Girart d’Amiens’s Escanor.
R.S. Loomis and D.D.R. Owen identified it with Firth of Forth, called in medieval times “Scottewatre,” indicating the Firth of Forth – an identification Cline clearly accepts, for he does not even use the name “Cotoatre,” simply calling Trebuchet’s home area the Firth of Forth.
