Accordingly they went to the Ricci family and offered to have the whole chapel painted and to pay the artist themselves. Moreover, they said that the arms or crest of the Ricci family should be painted in the most honourable part of the chapel, that all might see that the chapel still belonged to them. To this the Ricci family gladly agreed, and Ghirlandaio was set to work to cover the walls with his frescoes. 'I will give thee twelve hundred gold pieces when it is done,' said Giovanni Tournabuoni, 'and if I like it well, then shalt thou have two hundred more.' Here was good pay indeed. Ghirlandaio set to work with all speed, and day by day the frescoes grew. For four years he worked hard, from morning until night, until at last the walls were covered. One of the subjects which he chose for these frescoes was the story of the Life of the Virgin, so often painted by Florentine artists. This story I will tell you now, that your eyes may take greater pleasure in the pictures when you see them. The Bible story of the Virgin Mary begins when the Angel Gabriel came to tell her of the birth of the Baby Jesus, but there are many stories or legends about her before that time, and this is one which the Italians specially loved to paint. Among the blue hills of Galilee, in the little town of Nazareth, there lived a man and his wife whose names were Joachim and Anna. Though they were rich and had many flocks of sheep which fed in the rich pastures around, still there was one thing which God had not given them and which they longed for more than all beside. They had no child. They had hoped that God would send one, but now they were both growing old, and hope began to fade. Joachim was a very good man, and gave a third of all that he had as an offering to the temple; but one sad day when he took his gift, the high priest at the altar refused to take it. 'God has shown that He will have nought of thee,' said the priest, 'since thou hast no child to come after thee.' Filled with shame and grief Joachim would not go home to his wife, but instead he wandered out into the far-of fields where his shepherds were feeding the flocks, and there he stayed forty days. With bowed head and sad eyes when he was alone, he knelt and prayed that God would tell him what he had done to deserve this disgrace. And as he prayed God sent an angel to comfort him. The angel placed his hand upon the bowed head of the poor old man, and told him to be of good cheer and to return home at once to his wife. 'For God will even now send thee a child,' said the angel. So with a thankful heart which never doubted the angel's word, Joachim turned his face homewards.
