The legend of January

In Roman legend, there was a patron saint named Janus. He had two faces, one looking back on the past and the other looking forward to the future. People think that it is meaningful to choose his name as the name of the first month, and you can bid farewell to the old and welcome the new. English 65438+ January evolved from the Latin name Janus+ adjective suffix ary of the patron saint.

When Roman soldiers went out to war, they all passed under the arch symbolizing Janus and developed into a square Double Arch. Later, all forms of the Arc de Triomphe in European countries came from this. Janus is the most primitive god in Rome, and the Latin "1 month" also originated from him and evolved into the language of western countries.
