KEYWORDS
Gems, Egypt, Roman trade, gemmae, networks, hub, luxury, elite, Pliny, Natural History.

DATA

Files in .gdf / .gephi (which can be read by GEPHI) to obtain the representation of a network where meeting places of objects are associated with their places of origin. The Python program represents the network for a given time interval. The mission of this text is to make the routines easy for an unfamiliar user.

Databases usually require a standardization before being able to run a program on them, since the program has been programmed to receive the data in a specific way. The objective of the program is to filter certain years from a given database and generate the network between stamps and discovery sites. The program in question is called network-provinces.py and is written in Python 2.7.

The data are the result of cleaning processes of the data used here belong to the year 2021.

The data in general are gemstones consumed in Roman markets and featured in book 37 of Pliny's Natural History.
