According to tradition, the month of January was invented by the second ever king of Rome, Numa Pompilius, c. 700 BCE, as a dedication to Janus, the two-headed Roman God of Beginnings. (The Romans had a god for just about everything. In fact, turns out lovely Venus’s part time job was actually to preside over sewers. I am not kidding.)
The name Janus/Ianus came from the Latin word for “doorway”.
Numa had a temple to Janus erected, and its doors were symbolically shut during peace-time.
I wish all a happy and successful 2022. May Janus’s doors close everywhere, and remain sealed for everyone always.
