Saeculum

Look up saeculum in Wiktionary, the free dictionary.

A saeculum is a length of time roughly equal to the potential lifetime of a person or, equivalently, the complete renewal of a human population.^[1]

Background

Originally it meant the time from the moment that something happened (for example the founding of a city) until the point in time that all people who had lived at the first moment had died. At that point a new saeculum would start. According to

Emperors such as Claudius and Septimius Severus celebrated the passing of saecula with games at irregular intervals. In 248, Philip the Arab combined Ludi saeculares with the 1,000th anniversary of the founding of Rome. The new millennium that Rome entered was called the saeculum novum,^[6] a term that received a metaphysical connotation in Christianity, referring to the worldly age (hence "secular").^[7]

Roman emperors legitimised their political authority by referring to the saeculum in various media, linked to a golden age of imperial glory. In response, Christian writers began to define the saeculum as referring to 'this present world', as opposed to the expectation of eternal life in the 'world to come'.^[5] This results in the modern sense of 'secular' as 'belonging to the world and its affairs'.^[8]

The English word secular, an adjective meaning something happening once in an eon, is derived from the Latin saeculum.^[9] The descendants of Latin saeculum in the Romance languages generally mean "century" (i.e., 100 years): French siècle,^[10] Spanish siglo,^[11] Portuguese século,^[12] Italian secolo,^[13] etc.
