CURRICULUS, in our ancient writers, denotes the year or course of a year. Assum est hoc annorum Dominica incarnationis quater quinquagenis & quinques, quinis lustris, & tribus curriculis; i. e. In the year 1028: for four times fifty makes two hundred, and five times twenty hundred makes one thousand; five lustris are twenty-five years, and three curriculi are three years.
