iiii kal. sept.
A law of Gratian, Valentinian II and Theodosius I let anyone who followed a vein of stone through private land pay one tenth to the treasury and one tenth to the landowner, keeping the rest.
Background
The law speaks of "laborious digging". It sits in the Code's title on metal-workers and mines.
Rome today (1991–2020 avg): 29°/19°C (84°/66°F) · rain 21% of days
Fields & crops
Columella marks autumn beginning around 12 August; straw and stubble were gathered, figs and early fruit picked, and vineyards readied for the vintage per Columella 11.2.
Courts & law
A quieter legal month; many elite Romans were in the countryside. Under the empire, the imperial household's slaves and freedmen kept administration running.
Senate & politics
Renamed from Sextilis in 8 BC for Augustus, who had won his greatest successes in this month, including the capture of Alexandria in 30 BC per Macrobius 1.12.35.
Military
Armies stayed in the field; disease in hot camps was often as dangerous as battle modern view based on ancient accounts.
Festivals & religion
Portunalia (17 Aug.), Vinalia Rustica (19 Aug.), Consualia (21 Aug.), Vulcanalia (23 Aug.), when small fish were offered to Vulcan to ward off fire, and Opiconsivia (25 Aug.) per Varro and Festus. On the Ides, Diana's day, enslaved people had a holiday per Festus and Plutarch.
Daily life
The hottest weeks raised the risk of fire in the dense city, especially in timber-framed insulae; Augustus set up the vigiles, a fire brigade of freedmen, in AD 6 per Suetonius and Dio. Fevers peaked in late summer and early autumn; the sick poor relied on home remedies and shrines more than on doctors modern view.
