Medieval trade networks
I question the knowledge behind this map. The text states it depicts the state of affairs before &quot;the rise of Mongols&quot;, but one can find on it Sarai city which was established by Mongols, and, for example, Arkhangelsk which didn&#x27;t exist at those times either. Also some names are misspelled. Significant trade routes are omitted. No sources cited. Look too amateurish to me to take it seriously.<p>Update: there is a list if sources on the picture itself, I tried to look for it in the text at first. However, it doesn&#x27;t save the work from being evidently incorrect.
