Horace was in his placid Il Penseroso mood when he counselled the acceptance of each new-born day as possibly one’s last, and appropriating it accordingly:
“Inter spem curamque, timores inter et iras,
Omnem crede diem tibi diluxisse supremum:
Grata superveniet quæ non sperabitur hora.”
We might suggest suggestive parallels by the score, as this from a play of Leigh Hunt’s,
“One day—could you not try one day and then
Enjoy or fear another as it suited?
Ay, one—one—one. Try but one day, and then
Trust me if one day would not give you strength,”
