About us

The modern day definition of an "Actuary" dates back to 1762. Previously, use of the term had been restricted to an official who recorded the decisions, or "acts", of ecclesiastical courts. In ancient times the Actuary (or "Actuarius" in Latin) was the Secretary of the Roman Senate, responsible for compiling the Acta Senatus - the proceedings of the senate - or as we say today, simply the minutes of the meeting.

Ancient Rome newspapers were mostly written on metal or stone and would be posted up in popular areas like the Roman Forum.

The newspapers included details about the military, gladiatorial bouts, births, deaths and human interest stories. They also talked about welfare and there was a section called "Acta Senatus" which talked about the proceedings and decisions of the Roman senate.
