[XeTeX] enumerating quotations

[Jacobo Myerston]

Hi,

I'm writing a book in which I quote a significant number of ancient texts. I'm using the \quote environment for this as usual. Now, I would like to have a numbered label to refer back to these quotations along the book. So, I would like the \quote environment to behave somehow like \figure so that the quote is auto-numbered and labels located inside \quote get also an automatic number. 

Does anybody how to do this?

I'm using memoir.
