Full bellies make empty skulls. [ Proverb ]

The most magnificent and costly dome.
Is but an upper chamber to a tomb;
No spot on earth but has supplied a grave,
And human skulls the spacious ocean pave. [ Young ]

Great books, like large skulls, have often the least brains. [ W. B. Clulow ]

All skulls seem to laugh. Perhaps it is at the epitaph engraved on their tomb. [ Alfred Bougeart ]
