midnight
Diog . I. 68 . -RSB- `` Fill the goblets again , Knakias . Let us devote this last cup to the manes of the glorious Lysander ; and then I advise you to depart , for it is long past midnight , and our pleasure has reached its highest point . The true host puts an end to the banquet when his guests are feeling at their best . Serene and agreeable recollections will soon bring you hither again ; whereas there would be little joy in returning to a house where the remembrance of hours of weakness , the result of pleasure , would mingle with your future enjoyment . '' In this her guests agreed , and Ibykus named her a thorough disciple of Pythagoras , in praise of the joyous , festive evening .
