Figure 5: Network analysis map of the stamped exported samian of Ateius (5), from Arezzo (eastern Tuscany, Italy). Sites with an observed number of pots greater than the expected value and a 'Network Density Value' of 0.8 are indicated with a red dot and a blue line is drawn between the two sites. Hubs of samian trade with high correlations with adjacent sites comprising significant frequencies of Ateius (5) can be distinguished at Rome, Narbonne and Neuss. Sites with less than 5 occurrences are ignored (cf. Section 3). Red lines indicate province boundaries. Maps generated at http://www.rgzm.de/samian (02.12.2016).

Hubs of samian trade with high correlations with adjacent sites comprising significant frequencies of Aquitanus can be distinguished at London, Vechten, Mainz, Augst, Lyon and Narbonne.

Sites with an observed number of pots greater than the expected value and a 'Network Density Value' of 0.6 are indicated with a red dot and a blue line is drawn between the two sites. Hubs of samian trade with high correlations with adjacent sites comprising significant frequencies of Cinnamus ii can be distinguished at London and Corbridge. Sites with less than 5 occurrences are ignored (cf. Section 3). Red lines indicate province boundaries. Maps generated at http://www.rgzm.de/samian (02.12.2016).
