Guy (or Guido) of Valence was a bishop of Tripoli whose episcopate probably fell in the period 1228–1237.
He is an obscure figure, whose name is known only from the prologue of Philip of Tripoli's Latin translation of the Pseudo-Aristotelian Secretum secretorum,[1][2] in which he dedicates the work "to his most excellent lord Guido,[a] originally[b] of Valence, glorious pontiff of the city of Tripoli,[c] most strenuous in the cultivation of the Christian religion.
[5] In his prologue, Philip praises Guy's learning: "the clarity of your genius and the depth of your knowledge in letters exceeds that of all contemporaries on this side of the sea [i.e., Outremer], whether Latins or natives.
"[6] This flattery strongly suggests that Guy was a highly educated man, and the most probable place of his study was the studium specializing in Roman law within the Abbey of Saint-Ruf [fr] in Valence.
[7] Possibly he came to the Holy Land with Gerold of Lausanne, the bishop of Valence who was appointed patriarch of Jerusalem in 1225.
