Coal Outcrop

Accidentally brought into the kingdom of the Roman parchment from Constantinople, the monks managed to discover the methods of production and the possibility of using coal.

Parchments dated in the III - IV centuries AD. They described in detail how the Romans mined coal from natural outcrops, as it was used for drying grain and blacksmithing. As a result of this discovery, the newly found coal outcrop will be used for other purposes.
