Explanation: In the modern era, ever since the Industrial Revolution, society has been obsessed with timekeeping and the 'correct' time to get up, go to work, for how long, etc. Romans, like almost all pre-modern peoples, relied mostly on daylight and natural cycles to time their activities. 'Sol Invictus', the Unconquerable Sun, is the sun as envisioned as a deity by the Romans.
Having that in mind, a modern clock would be pretty useless in ancient Rome, as e.g. sunrise would always be the beginning of prima hora.
Sol Invictus: Get the fuck up mother fucker, its bright af out and getting hot.
You know, it's weird to me that people in places like Egypt would worship the Sun. You'd think the cool night is what they'd look forward to.
In Roman insulae, they often slept in windowless rooms. Many of them also woke before sunrise. They were generally woken by slaves, roosters and the increasing noise from people outside.
Most Roman apartments, even in insulae and slave quarters, had windows. Or, rather, shutters.
The bedrooms were often in the centre, in windowless rooms.
