The Tau cross is a T-shaped cross, sometimes with expanded ends
The Tau cross, also known as Saint Anthony's cross or Saint Anthony cross, is a T-shaped cross with three ends expanded. The name "tau cross" comes from its resemblance to the Greek letter tau (Τ), which corresponds to the Latin letter T. It is also called a crux commissa, one of the four basic types of iconographic representations of the cross.
The Tau cross has a rich history and has been used by various civilisations and religions throughout the ages. It is said to have originated in Egypt as a pagan symbol and was later adopted by Christians, including the Copts, who used it extensively on their gravestones. In its long history, the Tau cross has also been associated with Mithras, a Roman god, and Attis, a Greek god. In Norse mythology, Thor's hammer is shaped like a Tau cross, and in astrology, the zodiac sign Taurus the Bull takes its name from the letter 'tau'.
The Tau cross is particularly significant in Christianity, where it symbolises Christian devotion, redemption, and salvation. It is believed that Christ's first disciples adopted it as their talisman, and some experts suggest that the crucifixion cross was T-shaped rather than the classic cross commonly depicted today. The Tau cross is also associated with several Christian saints, including St Anthony of Egypt, who is said to have carried a T-shaped crutch, and St Francis of Assisi, who used the Tau as his personal seal and signature.
The Tau cross holds great importance for Franciscans, who wear it as a distinctive mark, often tied with a three-knot rope symbolising their vows of obedience, poverty, and chastity. St Francis of Assisi is credited with popularising the Tau cross within the Catholic Church, using it extensively in his artwork, writings, and signature. The Tau cross was also used by Pope Innocent III during the Fourth Lateran Council, where he encouraged Christians to mark it on their foreheads as a sign of conversion and penance.
Today, the Tau cross continues to be a recognisable symbol within both secular and religious groups, with various interpretations and meanings attached to it.

The Tau cross is associated with St. Francis of Assisi and the Franciscan order
The Tau cross is a T-shaped cross, sometimes with all three ends expanded. It is named after the Greek letter Tau, which it resembles. The Tau cross is associated with St. Francis of Assisi, who used it as his personal seal and signature, and it is also a symbol of the Franciscan order.
St. Francis of Assisi was present at the Fourth Lateran Council in 1215 when Pope Innocent III encouraged Christians to mark the Tau cross on the foreheads of those who were close to them. This was to be a sign of conversion and a symbol of the Crusades. St. Francis of Assisi embraced the Tau cross, marking it on the foreheads of those he met as a sign of salvation and the victory of Jesus Christ over evil. He also used it to sign his letters and paint it on walls, and it is said that he stretched his arms out wide to demonstrate to his friars that their habits embodied the symbol.
The Tau cross was important to St. Francis because its form reminded Christians of the Cross on which Christ was sacrificed for the salvation of the world. As the last letter of the Hebrew alphabet, it prophesied the Last Day and had the same function as the Greek letter Omega in the Book of Revelation. The Tau cross was also a symbol of Christian devotion, redemption, and salvation.
The Tau cross is still worn by those who recognise themselves in Franciscan spirituality, such as friars, nuns, and the faithful. It is usually made of olive wood, a poor and ductile material that recalls the faithful to a simple lifestyle. The Tau cross is tied with a three-knot rope, symbolising the three Franciscan vows of obedience, poverty, and chastity.

The Tau cross is a Catholic symbol of devotion, redemption and salvation
The Tau cross, also known as Saint Anthony's cross, is a T-shaped cross, resembling the Greek letter tau (or the Latin letter T). It is a Catholic symbol with a rich history and a profound significance in Christian devotion, redemption and salvation.
The Tau cross is deeply rooted in the Old Testament, specifically the Book of Ezekiel, where it is described as a mark on the foreheads of those from Israel who are to be saved from extermination. This symbolic use of the Tau cross is further reinforced in the New Testament, particularly in the Apocalypse of St John, also known as the Book of Revelation.
The Tau cross holds a special significance for Catholics, especially those who identify with Franciscan spirituality, including friars, nuns, and faithful followers. St Francis of Assisi, the founder of the Franciscan order, is known to have cherished the Tau cross deeply. He used it as his signature, seal, and a symbol of his devotion to God. St Francis of Assisi also marked the Tau cross on the foreheads of those he met as a sign of their conversion and salvation through Jesus Christ.
The Tau cross was also associated with St Anthony of Egypt, whose T-shaped staff and cassock bore the letter Tau. This association led to the Tau cross being known as Saint Anthony's cross. The Hospital Brothers of St Anthony, a Catholic religious order, wore habits marked with a blue Tau cross, further cementing its connection to the saint.
Beyond its biblical and saintly associations, the Tau cross holds symbolic meaning for Catholics. It represents Christian devotion, redemption, and salvation. The cross's shape reminds Christians of the Cross on which Christ was sacrificed for the salvation of the world. It signifies a commitment to following in the footsteps of the crucified Christ, embracing a life of obedience, poverty, and chastity.
The Tau cross is also a reminder of God's love and healing. It stands as a symbol of the innate goodness of God's creation and the potential for love and restoration, even in the face of hate and brokenness. For Franciscans, the Tau cross represents the core of their Franciscan life and a reminder to affirm nonviolent living and the dignity of all God's creations.

The Tau cross is associated with St. Anthony of Egypt, who is said to have leaned on a tau-shaped staff. The letter tau also appeared on his cassock in images. St. Anthony is believed to have carried a cross of this type, and it is said that he appeared in 1095 to a French nobleman whose son was sick. Following divine instruction to plant a tau-shaped cross, the boy was miraculously healed. This led to the use of such crosses as amulets to ward off disease during the Middle Ages.

They wore a black habit marked with a blue tau, which became associated with St. Anthony, their patron saint.
