Julius Caesar’s calendar reform of 46 B.C. instituted January 1 as the first of the year.

Building upon more ancient routes and creating a huge number of new ones, Roman engineers were audacious in their plans to join one point to another in as straight a line as possible whatever the difficulties in geography and the costs in manpower.
