Relevant studies [Altakhaineh (2017); Khodorkowsky (2014)] mention the Roman origin of several abbreviations which are still in use today, such as AM and PM (ante meridiem and post meridiem, meaning "before noon" and "after noon"), AD, which indicates the time period after the birth of Christ and originates from the Latin anno domini, meaning "in the year of our Lord", SPQR (Senatus populusque Romanuis) "the Senate and People of Rome." Another well-known and old acronym, cited in the Christian Bible, is INRI (Iesus Nazarenus Rex Iudaeorum) "Jesus of Nazareth King of the Jews." [Altakhaineh (2017); Khodorkowsky (2014)]
