Map: Bithynia in 77 BCE, its borders in gold among its neighbours
Bithynia in 77 BCE, when it held the most ground the borders dataset draws for it: 30,200 km². Its neighbours wear their tints, as on the atlas's own map. Borders from Cliopatria (CC BY 4.0), coast and rivers from Natural Earth, cities from Reba, Reitsma & Seto 2016 (CC BY 4.0), each city under the name it bore that year.
