a.d. XII Kal. Iul.
Ovid gives this day to Summanus, the obscure god of night-time thunder, whose temple dated from the war against Pyrrhus.
Background
Even Ovid did not know who Summanus was: "whoever he is". Roman tradition held that thunderbolts by day belonged to Jupiter and those by night to Summanus.
The temple by the Circus Maximus was dedicated during the war with Pyrrhus (280–275 BC), after a statue of the god on the Capitol was struck by lightning (Livy, Periochae 14).

Fields & crops
Grain harvest began in the lowlands: wheat was reaped, threshed on the threshing floor and stored. Columella advises clearing the floor and preparing granaries per Columella 11.2.
Courts & law
Normal court business. As on every Kalends, interest on loans fell due on 1 June, also the day of Carna, goddess of the body's vital organs, honoured with bean porridge and bacon per Ovid, Fasti 6.101–82.
Senate & politics
No fixed political dates, but in the Republic elections were often held in summer, with candidates canvassing in whitened togas late Republic; often July.
Military
Campaigns continued; harvests in enemy territory were sometimes burned or seized to feed armies.
Festivals & religion
The Vestalia (9 June), when bakers and millers garlanded their donkeys and mill-stones and women walked barefoot to Vesta's temple; the temple was cleaned on 15 June per Ovid, Fasti 6. Fishermen's games were held across the Tiber on 7 June.
Daily life
Harvest meant long days for gangs of hired reapers, often seasonal migrant labourers, alongside enslaved workers per Varro, Rust. 1.17, on hiring free labourers for harvests. Summer heat in Rome brought fevers, probably malaria in low, marshy districts; the wealthy left for hill or seaside villas per Horace and Celsus; malaria identification modern. The poor stayed in hot, crowded insulae.
