Porée (1675-1741), and humanist Pierre Brumoy (1688-1742). Composer Marc-Antoine Charpentier, who may have studied at the college, was its music master () between 1688 and 1698. The college library had about 40,000 volumes as of 1718, and included unique manuscripts such as the Chronicle of Fredegar (occasionally known for that reason as ) or Anonymus Valesianus. As in other Jesuit colleges, theatrical representations became increasingly prominent during the 17th century. Also as in other colleges, in 1660 the Jesuits opened an observatory, and in 1679 they created the elaborate sundials, augmented in the 18th century, that survive to this day on the northern side of the thanks to preservation campaigns in 1842 and 1988. The college undertook a rebuilding campaign in 1628, on a design attributed to Paris municipal architect Augustin Guillain. It expanded by acquiring more buildings, to its northeast from the recently-closed in 1641, and to its south from the in 1656 and 1660. In 1682, the college was able to expand further by acquiring the buildings of the to its east, after a century of attempts, as that college's activities were relocated elsewhere in Paris. Also in 1682, Louis XIV formally authorized the college to change its name to (). That act confirmed its royal patronage, despite the near-simultaneous Declaration of the Clergy of France and the kingdom's ongoing conflicts with the Papacy, to which the Jesuits were directly tied by their vows. Already in 1674, during his visit, Louis was said to have remarked ("this is my college"). A black marble slab with the inscription COLLEGIVM LVDOVICI MAGNI (College of Louis the Great) was promptly placed on the façade, in substitution to the earlier text COLLEGIVM CLAROMONTANVM SOCIETATIS IESV, which triggered controversy. (The anecdote was narrated by Gérard de Nerval in his short story , published in 1852 in the collection titled .) The new inscription survived later turmoil, and was relocated on the eastern side of the during the late-19th-century rebuilding. In 1700, Louis-le-Grand took over the École des Jeunes de langues, founded in 1669 by Jean-Baptiste Colbert, in line with the Jesuits' leadership in studying foreign languages and foreign cultures, reinforced since 1685 with the permanent mission in China initiated by six Jesuits from Louis-le-Grand. Antoine Galland, the first Western European translator of One Thousand and One Nights, had studied in this section and taught Arabic there from 1709. In 1742 the college had
