The etymology of Septimontium has been argued; those in the know believe the festival may take its name from saept-, (“divided”) in the sense of “partitioned off” instead of from septem (“seven”). The montes include two divisions of the Palatine Hill and three of the Esquiline Hill, among the traditional “seven hills of Rome”.
These seven hills were first occupied by small settlements that were not grouped nor recognized as a city called Rome. The seven hills’ denizens began to participate in a series of religious games, which began to bond the groups. The city of Rome, thus, came into being as these separate settlements acted as a group, draining the marshy valleys between them and turning them into markets. Later, in the early 4th century BC, the Servian Walls were constructed to protect the seven hills.
During the Septimontium in the Republican period, Romans refrained from operating horse-drawn carriages.
