As I'm short on time tonight I'm going to punt and start off with a few interesting links then revisit this topic as soon as possible!
Wiki is a nifty springboard to other sources on this vast topic.

- "Some Sorcerers do boast they have a Rod,
- Gather'd with Vowes and Sacrifice,
- And (borne about) will strangely nod
- To hidden Treasure where it lies;
- Mankind is (sure) that Rod divine,
- For to the Wealthiest (ever) they incline." -by Samuel Sheppard
