This painting I am working on is of a Religious Orders of Brothers that use the Greek letter 'Tau'
on their habits.
Note: St. Francis of Assisi marked his very first habit, a peasant's cloak, with
a 'T' in the front with a piece of chalk. He was always fond of the Greek 'Tau'
because of its visual association with the Cross of Christ. In the only handwriting of his
preserved, a blessing he wrote to his dear friend Bro. Leo, one can see that he signed it with a 'T'.
