Evensong.

A poem by Robert Herrick

Begin with Jove; then is the work half done,
And runs most smoothly when 'tis well begun.
Jove's is the first and last: the morn's his due,
The midst is thine; but Jove's the evening too;
As sure a matins does to him belong,
So sure he lays claim to the evensong.
