Yes. Known as the fylfot or gammadion, the hooked cross appeared in early Christian art including Roman catacombs, mosaics in the Church of the Nativity in Bethlehem, the Lindisfarne Gospels, Book of Kells, and medieval church decorations, vestments, and bells across Europe. It served as a cross variant often linked to Christ's victory or the Evangelists, centuries before Nazis adopted a rotated version in 1920.
