It might shock some, inspire others. But the truth is, the cross is a small-scale reproduction of the instrument of death on which Christ breathed his last. It became the «emblem» of Christians only after Constantine the Great extended the religious tolerance to their community in A.D. 313. Before that, Christ’s followers could only live their faith secretly.
Popular especially in its olive wood versions, the Tau is actually the last letter of the Old Hebrew alphabet. First adopted by the early Christians as a symbol of their devotion, later it became the coat of arms of the Antonine monks, as well as the distinctive symbol of the Franciscans. It comes hand in hand with the concepts of salvation and redemption.
