Thanks for posting. The YT video is very interesting. I’m always amazed at the incredible patience and painstaking work of the field archeologists. I can’t imagine the later lab work required to turn all that collected material back into objects.
One of your videos a while back (I think it was yours) showed the “mountain” in Rome comprised of smashed amphorae. It was cheaper to make new amphorae in Iberia to transport olive oil and grain to Rome than to transport empty amphorae back to the agricultural regions for re-use.
The archeologists in this video think the amphorae may be been used to bury small children or infants. It may have been a cheap way for the lower classes to get a coffin for their children.
The used jugs were so common and cheap to make that it probably didn’t make sense to ship something back, particularly from Rome, which imported from all over and exported much less. Also, the olive oil jugs would get rancid inside.
