I second the congratulations, Santa Barbara is such a beautiful place to live! Kinda regretting applying to schools where winter is an annual occurrence...
Do an honors thesis as said above, but be sure you can pare it down to a really good writing sample of circa 20-30 pages doublespaced; those are often the limits for history programs and it won't do as much good if you have a really excellent 60 page thesis.
As everyone comes up to the first deadlines, Dec 1 for alot of schools, I think it's important that we all, if possible, do something fun and mind-numbing over the holidays and remember the following. It's not the end of the world if we don't get in and it no way diminishes our self-worth.
I study history at Ohio State as an undergrad. We're really good at Ancient History, Byzantine, American Religious, and Eastern European. IF you have any specific questions about professors feel free to PM me
I'd try patching things up with your professor if possible; wouldn't think there's enough time for a new relationship to be built with another professor but there may be.
But the way primary sources from antiquity work would render 90% plus of them unusable; the distance between Alexander the Great and the first sources about him is about the same as Jesus and the Pauline epistles. This professor does not know Ancient History and its requirements for using sources at all. There are established and published methods for using each and every of these later primary sources.
