Trivia Labs: "Dawn Breaks Over Marblehead"

So we've heard the expression "Dawn breaks over Marblehead", and it typically refers to the act of suddenly realising something that was either very obvious, or that everybody else knew already.

But where did this phrase come from? Does it have a deeper meaning?

Here's what our Reserachers in the Trivia Lab have uncovered so far:

- This is a phrase that originated in the NE United States, specifically around Boston, MA.
- Marblehead is an actual coastal town in MA
- Marblehead is considered to be the birthplace of the US Navy
- The town of Marblehead is built almost entirely upon bedrock. Photos of the town show lots of exposed rock, adding credence to this assertion. Perhaps this is where the town derives it's name?
- The coast of MA is one of the first to recieve morning light in the US, as it is on the Eastern Seaboard

Trivia Lab conclusion:

The phrase is used because of the double meaning derived from the name "Marblehead". The town is built on bedrock, known to be incredibly dense. The proposition that an idea "dawns" upon somebody is a long-held concept, the "light of reason" suddenly appearing. A person considered "dense" would be somebody who did not have ideas come easily to them. Therefore, "dawn broke over marblehead" would be the same as "the idea occurred to the dense-headed". There is very little deeper meaning than this.
