Do you know what shepherds used to make their bags with? Scrotums. Yep. Sorry for breaking this vision to you but yes, ram’s balls.
I know this is a bit gross, but nevertheless effective, as you will not be able to un-see this plant anymore. Where ever you go, you will see, flapping in the wind, this little reminder of ancient crass humour: sheep’s sacks.

Satchels are quite commonly shown in David and Goliath images. 1 Samuel 17 specifically states "Then he took his staff in his hand, chose five smooth stones from the stream, put them in the pouch of his shepherd’s bag" It is worth noting that David was a shepherd.
In the case of Shepherd’s purse, the story is old and can be traced back all the way to Çatalhöyük, in modern day’s Turkey, where it was part of Neolithic diets as far back as 7,000 BCE. In western culture terms that is as ancient as it can get, making it a very old story.
So what is the story? Shepherd’s purse - Capsella bursa-pastoris - owns its name to the peculiarity of its seed pods, shaped like little hearts or, as the name suggests, little shepherd’s pouches.
Een reproductie van het schilderij De blauwe huik van Pieter Breughel (1559). De driehoekige hauwtjes van het plantje lijken heel erg op de tas waarin een herder zijn spulletjes met zich meedroeg. En die tas lijkt wel een heel erg universeel model te zijn geweest.
