His parents wished to send their sons to Eton or Harrow, but the family decided they could not afford the fees. In the summer of 1803, John was sent to board at John Clarke's school in Enfield, close to his grandparents' house. The small school had a liberal outlook and a progressive curriculum more modern than the larger, more prestigious schools. In the family atmosphere at Clarke's, Keats developed an interest in classics and history, which would stay with him throughout his short life. The headmaster's son, Charles Cowden Clarke, also became an important mentor and friend, introducing Keats to Renaissance literature, including Tasso, Spenser, and Chapman's translations. The young Keats was described by his friend Edward Holmes as a volatile character, "always in extremes", given to indolence and fighting. However, at 13 he began focusing his energy on reading and study, winning his first academic prize in midsummer 1809.
