This is an interesting day in ancient history.
The Romans, by which I mean ancients and also Catholics of the Roman Church, call this day ante diem ix kalendas septembres.
On this day in ancient Rome there were rites in honor of Luna at the Graecostasis mundus patet. In this case the mundus was a ritual pit which had a vaulted cover. Three times a year the Romans removed this cover (24 August, 5 October, 8 November). This is when the gates of the underworld were considered open and the manes (spirits of the dead) walked the streets of Rome.
In A.D. 72 St. Bartholomew was martyred perhaps at Albanopolis
In A.D. 79 the volcano Vesuvius erupted, destroying Pompeii, Herculaneum and Stabiae
In A.D. 410 Rome was sacked by Alaric, sparking a crisis of culture and identity for the Romans and leading St. Augustine to write The City of God.
What a difference a day makes.
