I was out at Southwark cathedral (or more accurately its library) last night to see Diana Darke talking about her book Stealing from the Saracens: How Islamic Architecture Shaped Europe. It was a lot better than I feared from the click-bait title. Apparently a possible Semitic root of Saracen is is srq "to steal, rob, plunder", more specifically from the noun sāriq (Arabic: سارق), pl. sariqīn (سارقين), which means "thief, marauder, plunderer." This makes "Stealing from Saracens" an hilarious phrase apparently.
It was quite tremendously tricky getting a drink in Borough Market before the event due to crowds and covid restrictions but the Whiskey and Ginger saved the day. There's a small room upstairs that appears to be little known.
