The Labarum was the Roman Emperor Constantine's Christian standard after his triumph at the Milvian Bridge in A.D. 312.
The standard consisted of a purple banner with the Greek slogan, "In this sign [of the Cross] you shall conquer." It was suspended from a long and gilded spear, with a chi-rho symbol of Christ at the top.
Fifty soldiers guarded this standard.
