Tradition and legend attribute the discovery of the True Cross to Saint Helena, mother of Constantine the Great who went to Palestine during the fourth century in search of relics. Eusebius of Caesarea was the only contemporary author to write about Helena's journey in his "Life of Constantine". But Eusebius did not mention the True Cross, although he dwelt on the piety of Helena and her reporting the site of the Holy Sepulchre. In the fifth century writings by Socrates Scholasticus, Sozomen and Saint Theodoret report on the finding of the True Cross.
