The cross was used in the ancient world as a symbol of execution by crucifixion. And it became an important part of the Christian liturgy and art as a symbol of Jesus Christ's death. This Christian symbol is a long vertical bar intersected at right angles, usually about 2/3rds up by a shorter horizontal bar.

Crosses were carried in holy processions. Later on, crosses were placed on altars in churches and erected outdoors in markets and along roads.
