What does the Latin 'et pol' mean?

The Latin phrase 'et pol' is an interjection, which interrupts the flow of speech or writing, for dramatic emphasis. In English, it's rendered as follows: And by Pollux indeed; or And really indeed; or And truly indeed. The reference is to Pollux, the immortal who split his powers in half to share with, and thereby save, his mortal twin brother Castor. He therefore was viewed with great respect, by the ancient Romans and the even earlier, ancient Greeks, as generous source of help and therefore the object of prayer requests.
