I am in Bahrain for the Islamic Archaeology in Global Perspective conference.
We have been hearing papers outlining the nature of the Islamic occupations from Brunei to Morocco via Turkmenistan, Yemen, Saudi and many others. In some areas such as the Levant, these rather late, medieval, levels were dug straight through to get to the older, Classical or Biblical-era, levels that were of more interest to the excavators. I will be talking about West Africa later today; there the problem has sometimes been the opposite, where sites were excavated down to Islamic levels – enough to try and show that a site mentioned in Arabic written records had been identified – and no further. Neither approach is considered acceptable today, by the way!
