Lyon escaping from New Prison
Lyon escaping from New Prison

Elizabeth Lyon (fl. c. 1722–1726) was an English thief and prostitute. By 1723, she was working in London as a prostitute at the Black Lyon alehouse, where she began a relationship with Jack Sheppard. At Lyon's instigation, Sheppard stole from places where he worked, then moved to housebreaking; Lyon became an accomplice to his crimes. Sheppard was arrested on several occasions and broke out soon after incarceration, often assisted by Lyon. In May 1724, she was arrested when visiting him in prison, and the pair broke out of New Prison (pictured). After Sheppard's execution in November 1724, Lyon entered into relationships with other men who were, or became, involved in housebreaking, and she sometimes assisted them. She was arrested in March 1726 and was transported to Maryland. Lyon's notoriety is based on her connection to Sheppard; in the years following his execution, novels were published and plays performed that retold their story. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
