The story goes that the Perez family had been very rich, but, however it may have been, that was not the case when the artist was born. One day after his mother had gone to church, Murillo being left at home alone, retouched a picture that hung upon the wall. It was a picture of sacred subject--"Jesus and the Lamb." He thought he could make some improvements in it, so he painted his own hat upon the head of Jesus and changed the lamb into a little dog. His mother was a good deal shocked at what seemed to her an irreligious act, though it showed the family genius. After that the boy was found to be painting upon the walls of his schoolroom, and making sketches upon the margins of his books, though he did little else at school. He had one sister, Therese, and they were left without father or mother before the artist was eleven years old. It was at that time that he received the name of "Murillo" by which he is known. It came about thus: After the death of his parents he went to live with his mother's sister, the Doña Anna Murillo, who had married a surgeon called Juan Agustin Lagares, and since the little artist was to live with his aunt, he soon became known by her family name. There, in her home, he and his sister Therese, were brought up, but he was not to become a surgeon like his uncle-in-law, but an artist like his uncle Juan, the teacher in Seville. That uncle took him in hand, taught the boy to draw, to mix colours, to stretch his canvas, and soon Murillo's genius won the love of master and pupils. In peace and reasonable comfort he served a nine years apprenticeship, and painted his first important, if not especially great, pictures. These were two Madonnas, one of them "The Story of the Rosary." St. Dominic had instituted the rosary; using fifteen large and one hundred and fifty small beads upon which to keep record of the number of prayers he had said; the large beads representing the _Paternosters and Glorias_ and the small ones, the _Aves_. This practical way of indicating duties helped the heedless to concentrate their attention, and did much to increase the number of prayers offered. Indeed, it is said that "by this single expedient Dominic did more to excite the devotion of the lower orders, especially of the women, and made more converts, than by all his orthodoxy, learning, arguments, and eloquence." It was this incident in the history of the Catholic Church that Murillo commemorated. When the artist was twenty-two years old, his uncle, Juan del Castillo, broke up his home and went elsewhere to live, leaving the artist without home or means, and with his little sister to take care of. Without vanity or ambition, but with only the wish to care for his sister and to get food, the marvellous painter took himself to the market place, and there, wedged in between stalls, old clothes, vegetables, all sorts of wares, like a wanderer and a gypsy, he began his career.
