The emperor deeply revered the victory-bearing Sign of the Cross of the Lord, and also wanted to find the actual Cross upon which our Lord Jesus Christ was crucified. For this purpose he sent his own mother, the holy Empress Helen, to Jerusalem, granting her both power and money. Patriarch Macarius of Jerusalem and St Helen began the search, and through the will of God, the Life-Creating Cross was miraculously discovered in 326.
