Pacelli spent one year at Capranica. The generally accepted reason for his brief time at the college was put down to his indifferent health. From 1896 until his ordination in 1899 Pacelli continued his priestly formation in the family home. This was a highly unusual, but not unknown, situation.
The young Pacelli also attended courses in languages and history at Rome's primary civil university, La Sapienza, canon and civil law at the Ateneo Pontificio di Sant’Appolinare founded by Pius IX in 1853, and the pontifical university, the Gregorian, for philosophy and theology. By the standards of late Tridentine Catholicism, Pacelli enjoyed a full and well-rounded education. By all accounts he was an able and gifted student.
