This book reviews Samian ware chronology, c. AD 150-275. A dating scheme is proposed, based upon the stratigraphic association of Samian ware with coins, and using the statistical strength of association between potters or styles with each other and with dated deposits. A new model is also presented for estimating time-lapses between minting and loss for coins of the period. The results extend Central Gaulish Samian ware later than hitherto supposed, and revise the relative sequence of potters. The average period of use of Samian vessels is often quite long, and therefore, close dating of Samian ware is questioned. A concluding discussion looks at the socio-economic significance of Samian ware decline.
