Man Know Thyself......

Not much else to say really :-)
This is a plaque on Coiners Wharf Apartments in Mytholmroyd, Near Hebden Bridge - I'm not sure what it's all about - the apartments are in a converted building.
"Man Know Thyself" seems to be a profound Biblical quotation, and the beehive is a sign of work/industry.
Answers on a postcard please, to.......................... :-)
