The Christogram and the Labarum
The "Chi Rho" or "Barred Rho" monogram is one of the
oldest Christian symbols. It is especially associated
with the emperor Constantine I
and his vision of the Holy Cross
at the Milvian Bridge.

Very interesting history of the XP ligature,
which was used to mean "time" (chronos)
or "100 men" (hekatontarchia) in
imperial Roman texts before Constantine,
and of the barred-rho, now usually read as
XP but originally abbreviating the -taur-
in stauros ("cross").
