St. Dominic’s instructions were that it should be a sackcloth habit, of the kind worn by his own brotherhood, and that its colour might be at the discretion of the wearer so long as it was sombre. As it had ever been the custom of the Church to bless the “sack” or tunic worn by members of religious confraternities or by those upon whom it had been imposed as a penance, such a garment was called a _saco bendito_, which in course of time was contracted into _sanbenito_, though also known by its proper Spanish name of _zamarra_. When the crusade against the Albigensian heretics was at its height in Southern France, not only did the crusaders wear the cross upon their garments, but all faithful Catholics assumed it for their protection; for--as on the night of the St. Bartholomew, some four centuries later--no man’s life was safe if he did not display that device. St. Dominic desired that the penitent should enjoy the same protection, but so that his penance should still be proclaimed, he was ordered to wear two crosses, one on each breast. Later, when the wars of religion had ceased, and the general wearing of the cross was abandoned, the Council of Toulouse decreed, in 1229, that these penitential crosses should be yellow, whilst the Council of Beziers, four years later, going further into the matter, ordained that they should be two and a half hands long (vertical) by two hands wide (horizontal), and that they should be made of cloth of the width of three fingers. Instead of being worn upon the breast, as hitherto, they were now placed one on the breast and one on the back, with a third on the hood or veil if hood or veil were worn. For abettors of heresy the following solemn penance was enjoined by the Council of Tarragona in 1242: “On All Saints’, on the First Sunday in Advent, on the feasts of Christmas, the Circumcision, the Epiphany, St. Mary of February (Purification), St. Mary of March, and all Sundays in Lent, the penitents shall go to the Cathedral to take part in the procession. They shall be dressed only in their shirts, barefoot, their arms crossed, and they shall be whipped in the procession by the bishop or parish priest. Similarly shall they repair to the Cathedral on Ash Wednesday in their shirts, barefoot, their arms crossed, and submit to banishment from church for all Lent; so that during that season they must remain at the church door and hear the service thence. On Thursday in Holy Week they shall come to the church to be reconciled in accordance with the canonical provisions, it being understood that this penance of remaining out of the church through Lent and of being whipped in procession on the days appointed shall be performed yearly for the remainder of the penitents’ lives.” * * * * *
