Dr. Andrew Birley and Justin Blake, the two main archaeologists, at Vindolanda.
Dr. Birley is discussing the Roman bacon sandwich and a typical diet for a soldier based at Vindolanda.
The "Y" shaped drain which is shown at one point...is on the floor of one of the "corridor" or "strip" houses (shops) which form part of the Roman vicus or village. This would have been the floor of the butcher's shop where the blood was collected to make black pudding. Both cooked produce (hence the bacon sarnie) and livestock would have been sold from here. No health and safety rules in those times!
