Roman emperors Theodosius II and Valentinian III issue a new law limiting where people can draw a cross.
This new law states:
"As it is Our diligent care to guard in every way the religion of the Celestial Divinity, We specially command that no one shall be permitted to trace, carve, or paint the sign of Christ the Saviour either upon the earth, upon stone, or upon marble placed in the earth, but it shall be erased wherever found; and anyone who attempts to violate Our laws in this respect shall be subject to a heavy penalty." [CI 1.8.1]
This is a precursor to much later laws against the desecration of religious and national symbols. The Roman state is imposing a "heavy penalty" on anyone who fails to show the sort of respect and deference to one particular Christian symbol that certain Christian leaders must be demanding.
