Catullus 116

Often seeking with an eagerly hunting mind to be able to send you the songs of the son of Battus, with which I might soften you for us and lest you try to send hostile missiles up against my head, I see now that this labor was taken up in vain, Gellius, and that our prayers here were not influential. We will avoid your missiles sent against us: but, affixed by ours, you will pay the penalty.
