In all thy humours, whether grave or mellow, Thou'rt such a touchy, testy, pleasant fellow; Hast so much wit, and mirth, and spleen about thee, There is no living with thee, nor without thee.

-Addison,Joseph
  In The Spectator, no.68,18 May.

Who saw life steadily, and saw it whole: The mellow glory of the Attic stage; Singer of sweet Colonus, and its child.

-Arnold, Matthew
  Of Sophocles. The Strayed Reveller, and Other Poems,'To a Friend'.

The mellow lin-lan-lone of evening bells.

-Tennyson
