Carpe diem is a Latin aphorism, usually translated "seize the day", taken from book 1 of the Roman poet Horace's work Odes.

Quintus Horatius Flaccus, commonly known in the English-speaking world as Horace, was the leading Roman lyric poet during the time of Augustus. The rhetorician Quintilian regarded his Odes as just about the only Latin lyrics worth reading: "He can be lofty sometimes, yet he is also full of charm and grace, versatile in his figures, and felicitously daring in his choice of words."
