Cotatre, Cotovatre, Scottewatre
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.
