Editing Pope Gregory XIII (section)

===Formation of clergy and promotion of the arts and sciences===
Gregory XIII was a generous patron of the [[Jesuit]] colleges in Rome.{{sfn|Crowther|1999|p=8}} The Roman College of the Jesuits grew substantially under his patronage, and became the most important centre of learning in Europe for a time.  It is now named the [[Pontifical Gregorian University]]. Pope Gregory XIII also founded numerous [[seminaries]] for training priests, beginning with the [[German College]] at [[Rome]], and put them in the charge of the Jesuits.

In 1575, he gave official status to the [[Oratory of Saint Philip Neri|Congregation of the Oratory]], a community of priests without vows, dedicated to prayer and preaching (founded by Saint [[Philip Neri]]). In 1580 he commissioned artists, including [[Ignazio Danti]], to complete works to decorate the [[Apostolic Palace|Vatican]] and commissioned [[The Gallery of Maps]].

Gregory also transformed the Dominican studium founded in the 13th century at Rome into the College of St. Thomas in 1580, as recommended by the Council of Trent. This college was the precursor of the [[Pontifical University of Saint Thomas Aquinas]] ''Angelicum''.
