Tempora mutantur is a Latin adage meaning "times change". It is also stated in various longer hexametric forms, most commonly Tempora mutantur, nos et mutamur in illis, meaning "Times change, and we change with them". The phrase is not found in Classical Latin, but is a variant of phrases of Ovid, to whom it is sometimes misattributed. Instead, it dates to early/mid 16th century Germany, in the context of the Protestant Reformation, and it subsequently was popularized in various forms. See history for history and other forms.
