It is not free from doubt because, though some of the witnesses, whose testimony is given in Documentos inéditos, vol. X, pp. 146-174, are doubtless in good faith in their evidence as to Luis de Leon's Jewish descent, they refer to events which happened long before; and their memories are apt to play them false and their narratives are muddled. Luis de Leon appears to point to these depositions when he says: 'Y no se hallará en memoria de hombres ni de escrituras ciertas, que nombrada y señaladamente alguno de todos mis antecesores se haya convertido á la fe de nuevo' (Documentos inéditos, vol. X, p. 386). In common fairness, it should be said that the statement of P. Mendez [see note [1]] is more in the nature of assertion unsupported by full evidence.
