the phoenix and the turtle

[.....//
-----
Beauty, truth, and rarity.
Grace in all simplicity,
Here enclos'd in cinders lie.

Death is now the phoenix' nest;
And the turtle's loyal breast
To eternity doth rest,

Leaving no posterity:--
'Twas not their infirmity,
It was married chastity.

Truth may seem, but cannot be:
Beauty brag, but 'tis not she;
Truth and beauty buried be.

To this urn let those repair
That are either true or fair;
For these dead birds sigh a prayer. ]

William Shakespeare
