Rocko, I'm not a big fan of asteroid meanings based upon a very incomplete and superficial knowledge of Greek and Roman mythology. A really good website on Greek mythology is www.theoi.com .

The history of the Vestal virgins and the goddess Vesta was different than what your linked site suggests.

The idea that asteroids are associated with, let alone rule, particular signs has no basis in research, so far as I know. If you've got evidence otherwise, I would love to see it.

I think asteroids can have meaning in a chart, but we have to know what we are using them for, and why. I use only the conjunction. There are over 20,000 asteroids, and if we're not judicious about them, we can make a chart mean anything we want.
