They loved their monastery, and, as the centuries went by, they made it more and more beautiful. The people gave rich offerings and builders came from foreign lands, skilled in stonework and other arts. Carvings were made for the church, pictures were painted on the walls, and flowers and trees were brought from the Holy Land to plant in the gardens. In this way came the cedar trees and the juniper, and certain plants that now grow wild in parts of the country like the poisonous hellebore, the grape hyacinth and the little fritillary or snake's head. Great men brought gifts of frankincense and myrrh, to be burned in the church on holy days, or jewels for the altar, and silk from the east for hangings, but the greatest treasure of all was the "relic." People would travel many miles to see this, for those who saw it could be healed of their sickness or forgiven for their sins. There were many curious relics. There were little bits of wood, that men believed belonged to the real cross, on which Christ was crucified, and thorns, which were said to have come from His crown. S. Louis, King of France, built the beautiful Sainte Chapelle in Paris, where he might keep the crown of thorns, which the Crusaders brought from Palestine. The monastery was usually built round a square garden or lawn. On one side was the church, on another the hall and large kitchens and pantries, for there were often visitors, some of high estate, and they must be royally feasted. In the Rule of S. Benedict it was written, "Let all guests who come to the monastery be entertained like Christ Himself; because He will say, 'I was a stranger and ye took me in'." The guest-house must stand apart "so that the guests, who are never wanting in a monastery, may not disquiet the brethren by their untimely arrivals." Anyone could claim a lodging for two nights, and in a few monasteries there was stabling provided for as many as three hundred horses. There was a long dormitory where the monks slept. It was the custom for them to get up at midnight to make a procession into the church by the night stairs. There they said matins and lauds (the last three psalms), and then returned to the dormitory to sleep if it were winter until daybreak, if summer till sunrise. Only those who had worked hard in the fields all day were excused. They dressed by the light of the wicks set in oil in little bowls at either end of the dormitory. In the cloisters were troughs for washing before meals, filled with water by taps; and above were little cupboards for towels.
