Sadness

 Child of mortality, whence comest thou? Why is thy countenance sad, and why are thine eyes red with weeping?
       Anna Letitia Barbauld—Hymns in Prose. XIII.   1

Of all tales ’tis the saddest—and more sad, Because it makes us smile.

       Byron—Don Juan. Canto XIII. St. 9.   2

A feeling of sadness and longing,

 That is not akin to pain,

And resembles sorrow only

 As the mist resembles the rain.
       Longfellow—The Day is Done. St. 3.   3 
     Yet be sad, good brothers,
   *    *    *    *    *

Sorrow so royally in you appears, That I will deeply put the fashion on.

       Henry IV. Pt. II. Act V. Sc. 2. L. 49.   4

We look before and after,

 And pine for what is not,

Our sincerest laughter

 With some pain is fraught:

Our sweetest songs are those that tell of saddest thought.

       Shelley—To a Skylark. St. 18.   5

’Tis impious in a good man to be sad.

       Young—Night Thoughts. Night IV. L. 676.
