> eg ppl buried at Monkton up Wimborne, Dorset, c. 3300 BC---often said on basis of lead isotope results to prob be from Mendips, but this >
> doesn't fit w/ oxygen+strontium, which together don't really match anywhere in Britain--oxygen esp v high, more likely Iberia/Africa...?
@caitlinrgreen Resuming link with new alias. No mention of tin trade in Bronze Age or Visigoths who'd be implicated in "period c. 475–550"?
@Dai_James1942 Tin trade def credible; goth in Gloucester at end of Roman period, but via E Europe; trade prob direct & via Byzantine ships?
@caitlinrgreen Point taken. I had not considered the Byzantines.
@Dai_James1942 Campbell's analysis of the traded 'package' of goods in 5th-6thC suggests direct imperial trading most likely scenario :)
@caitlinrgreen @hbdchick Cadiz is well positioned as the gateway to the Atlantic. It should not be lightly dismissed.
