This Little Piggy

Piggy banks date back to at least the 2nd century BC but they weren't always in the shape of a pig. Most commonly any empty container could be used to store coins but around the 15th century metals were expensive and seldom used for household purposes so most containers were made for a orangish colored clay called pygg. People began calling the containers pygg jars and eventually (around the 19th century) potters started making them in the shape of a pig which caught on in a big way leaving us with the now common term "piggy bank". For filing purposes today's post should go under "learned something new",unless of course you already knew!
