Juan de Ávalos began his training very early. As a six-year-old he was a student of D. Juan Carmona, pastor of the Church of Santa Eulalia, who taught him and three other children to draw. de Ávalos's family moved to Madrid shortly after that, as his father's eyesight deteriorated. In Madrid, de Ávalos's father showed his son's drawings to the painter Manuel Benedito. The famous artist was surprised to see the quality of work of a child. He didn't believe a child could draw so well until he went to de Ávalos at work. Convinced of the boy's talent, he advised de Ávalos's father to take his son to the Casón del Buen Retiro.
