Also called St. George's Cross. The Greek Cross has all members the same shape and form (crux quadrata) and was popular with Greek Christians who favored symmetrical art. This cross can be seen on grave stones in the Roman catacombs. In 12th century , crusaders from England adopted the design for their own use, and took it back to England as the cross of St. George. The Greek Cross is also printed as a 'plus sign' in liturgical documents to indicate where the priest should make the sign of the cross. A variation of the Greek cross is the emblem of the Red Cross. More than one hundred years ago, the International Red Cross was founded to aid those wounded in battle.
