dies Dominicus



From diēs (day) +‎ dominicus (of the Lord (adj.)). Since the head-noun diēs could be either masculine or feminine, the phrase has a feminine counterpart in diēs Dominica.

Found from about 200 CE onwards as a Christian replacement for the pagan diēs Sōlis (Sunday, literally day of the sun-god Sol). Completely erased the latter, as far as Romance is concerned.
