But sometimes one thing would be left out and sometimes another, or different people would add wonderful stories of their own, which would become part of the true story. And so, when at last these histories come to us, we find we have lost a great deal, and perhaps not gained very much. The two saints, to whose story we are going to listen to-day, are of this long-ago time, and the history of their lives has almost faded from men's memories. But whoever happens to go to Florence, that city of flowers, where the old Medici family has left its mark on every corner, will see the portraits of our two saints wherever they go. For the old painters loved to tell the saint-stories in their own beautiful way, and to-day the little dark-eyed Italian children can read them without books, for they are told more plainly and far more beautifully than in any written story. Cosmo and Damian were brothers, and were born in Arabia three hundred years after Christ. When they were quite little boys their father died, and they were left alone with their mother. She was a Christian, and taught her boys, as soon as they were old enough to understand, that though they had no earthly father, God was their Father in heaven. She told them that the great King of Heaven and Earth called them His children, and he who could do a mean or cruel act, or stain his honour by an untruthful word, was not worthy to be called a King's son. And because they were noble she taught them that they must do noble deeds, bravely defend and protect the weak, and help those who could not help themselves. So the boys grew up straight and strong in mind and body. Their bitterest punishment was to feel that they had done anything unworthy of their King, and although they often made mistakes and did wrong thoughtlessly, they never went far astray since God's honour was their own. Their mother was rich, for their father had had great possessions, but there were so many poor and suffering people around their home that it was almost impossible to help them all. So the boys learned early to deny themselves in many ways, and often gave up their own dinner to the starving poor. In that land there was a great deal of sickness and suffering, and this was a great trouble to Cosmo and Damian. They could not bear to see people in pain, and be unable to help them. They often thought about this, and at last determined to learn all about medicine, and become doctors, so that they might at least soften suffering when they could not cure it. After years of patient study they learned to be very clever doctors, and their kind hearts and gentle hands soothed and comforted those who were in pain, even when skill could do nothing for them. They visited rich and poor alike, and would take no money for their services, for they said it was payment enough to know they had been able to make the worlds suffering a little less.
