This didn't make life easier for Isidore. To the contrary, Leander may have been holy in many ways, but his treatment of his little brother shocked many even at the time. Leander, who was much older than Isidore, took over Isidore's education and his pedagogical theory involved force and punishment. We know from Isidore's later accomplishments that he was intelligent and hard-working so it is hard to understand why Leander thought abuse would work instead of patience.
One day, the young boy couldn't take any more. Frustrated by his inability to learn as fast as his brother wanted and hurt by his brother's treatment, Isidore ran away. But though he could escape his brother's hand and words, he couldn't escape his own feeling of failure and rejection. When he finally let the outside world catch his attention, he noticed water dripping on the rock near where he sat. The drops of water that fell repeatedly carried no force and seemed to have no effect on the solid stone. And yet he saw that over time, the water drops had worn holes in the rock.
Isidore realized that if he kept working at his studies, his seemingly small efforts would eventually pay off in great learning. He also may have hoped that his efforts would also wear down the rock of his brother's heart.
When he returned home, however, his brother in exasperation confined him to a cell (probably in a monastery) to complete his studies, not believing that he wouldn't run away again.
Either there must have been a loving side to this relationship or Isidore was remarkably forgiving even for a saint, because later he would work side by side with his brother and after Leander's death, Isidore would complete many of the projects he began including a missal and breviary.
In a time where it's fashionable to blame the past for our present and future problems, Isidore was able to separate the abusive way he was taught from the joy of learning. He didn't run from learning after he left his brother but embraced education and made it his life's work. Isidore rose above his past to become known as the greatest teacher in Spain.
His encyclopedia of knowledge, the Etymologies, was a popular textbook for nine centuries. He also wrote books on grammar, astronomy, geography, history, and biography as well as theology. When the Arabs brought study of Aristotle back to Europe, this was nothing new to Spain because Isidore's open mind had already reintroduced the philosopher to students there.
As bishop of Seville for 37 years, succeeding Leander, he set a model for representative government in Europe. Under his direction, and perhaps remembering the tyrannies of his brother, he rejected autocratic decision- making and organized synods to discuss government of the Spanish Church.
Still trying to wear away rock with water, he helped convert the barbarian Visigoths from Arianism to Christianity.
He lived until almost 80. As he was dying his house was filled with crowds of poor he was giving aid and alms to. One of his last acts was to give all his possessions to the poor.
When he died in 636, this Doctor of the Church had done more than his brother had ever hoped; the light of his learning caught fire in Spanish minds and held back the Dark Ages of barbarism from Spain. But even greater than his outstanding mind must have been the genius of his heart that allowed him to see beyond rejection and discouragement to joy and possibility.
