Popular tradition maintains that this little prayer was given by St. Anthony to a poor woman who was troubled by temptations. It has been popular prayer amongst Franciscans for centuries. Pope Sixtus V, a Franciscan himself, had the prayer carved at the base of the obelisk, which he erected in St. Peter's Square in Rome in 1585.
Ecce Crucem Domini!
Fugite partes adversae!
Vicit Leo de tribu Iuda,
Radix David! Alleluia!
Behold the Cross of the Lord!
Be gone all evil powers!
The Lion of the tribe of Judah,
The root of David has conquered! Alleluia!
