Note 088
Cyril (apud Baron. A.D. 353, No. 26) expressly observes
that in the reign of Constantine the cross had been found in
the bowels of the earth; but that it had appeared, in the
reign of Constantius, in the midst of the heavens. This
opposition evidently proves that Cyril was ignorant of the
stupendous miracle to which the conversion of Constantine is
attributed; and this ignorance is more surprising, since it
was no more than twelve years after his death that Cyril was
consecrated bishop of Jerusalem by the immediate successor
of Eusebius of Caesarea. See Tillemont, em. Eccles. tom.
viii. p. 715.
