On Mermaids...William Shakespeare

OBERON:

My gentle Puck, come hither.
Thou rememberest since
Once I sat upon a promontory,
And heard a mermaid on a dolphin's back
Uttering such dulcet and harmonious breath
That the rude sea grew civil at her song,
And certain stars shot madly from their spheres,
To hear the sea-maid's music?

From.....A Midsummer Night's Dream 

ANTIPHOLUS OF SYRACUSE:

O, train me not, sweet mermaid, with thy note,
To drown me in thy sister's flood of tears.
Sing, siren, for thyself, and I will dote;
Spread o'er the silver waves thy golden hairs,
And as a bed I'll take them and there lie,
And in that glorious supposition think
He gains by death that hath such means to die;
Let Love, being light, be drowned if she sink!

From...Comedy of Errors
