an edition of the Latin classics prepared in the reign of Louis XIV of France. The series was supervised by Pierre-Daniel Huet (Huet, Pierre-Daniel) from 1670 to 1680, when he was working with Jacques Bossuet, tutor to Louis XIV's son, the dauphin Louis. The name of the series was derived from a Latin inscription on the title page of the books, in usum serenissimi Delphini (“for the use of the most serene Dauphin”).
