Baronius (Annal. Eccles. A.D. 326, No. 42-50) and Tillemont (Mem. Eccles. tom. vii. p. 8-16) are the historians and champions of the miraculous invention of the cross, under the reign of Constantine. Their oldest witnesses are Paulinus, Sulpicius Severus, Rufinus; Ambrose, and perhaps Cyril of Jerusalem. The silence of Eusebius and the Bordeaux pilgrim, which satisfies those who think, perplexes those who believe. See Jortins sensible remarks, vol. ii. p. 238-248.
