CURRICULUS, in our ancient writers, denotes
the year or course of a year. Actum est hoc annorum
Dominicæ incarnationis quater quinquagenis et quin-
quies quinis lustris, et tribus curriculis, i. e. In the year
1028; for four times fifty make two hundred, and five
times two hundred make one thousand; five lustres are
twenty-five years, and three curriculi are three years.
