Sleep, rest of nature, O sleep, most gentle of the divinities, peace of the soul, thou at whose presence care disappears, who soothest hearts wearied with daily employments, and makest them strong again for labour!
While strength and years permit, endure labor; soon bent old age will come with silent foot.
[Lat., Dum vires annique sinunt, tolerate labores.
Jam veniet tacito curva senecta pede.]
