Uh, finally to the sundial, the first round sundial that we kind of know as a sundial, um, seems like it was created by a Greek philosopher named, uh,

Anaximander, very cool name, not Alexander, but Anaximander, of Miletus.

This was 6th century B.C., but again, probably still tracking seasons at this point.

The first sundials out of Greece that actually marked hours, like when people started keeping track of the hourly time, and as we'll see, it just gets more specific until eventually, much later, we'll get to minutes, but the hourly timekeeping started in 350 B.C.E.

And then very quickly after that, around 280 BCE, they came up with the hemicycle, which is imagine like a cube block of stone with a basin, a bowl carved out of the middle.

And then they managed to cut it perfectly in half.

So that you just have half of a bowl.

Because it turns out all you need is half a bowl to make a sundial like that.

And I really do wonder if somebody built them like that.

Like they'd make one, split it in two, and then all of a sudden they had two hemicycles to sell.

You're getting really good at describing things at this juncture in your career.
