DIESPITER, in antiquity, a name given to Jupiter; and signifying dies pater, "father of the day." St Augustin derives the name from dies, "day," and pater, "production, bringing forth;" it being Jupiter that brings forth the day. Of which sentiment were Servius and Macrobius; the former adding, that in the language of the Osci they called him Lucenetus, as Diespiter in Latin.
