'Vivat in aeternum' is a Latin phrase that translates as "Que viva [someone] forever." although it would be more accurate as 'Vivat in æternum', with the letters /ae/ in ligature, but as it does not exist in Spanish it is common to see it replaced by the two vowels and even by the /e/ only, but this is already more debatable. It is also the name of a motett composed by Nicolas Roze and executed during the coronation of Napoleon I of France. See Vivat Imperator in aeternum .
