Xenia epigram

A xenia epigram is an epigram attached to a gift, sometimes as represented in a xenia mosaic. Originally found in Latin literature, it was revived in the nineteenth century.

An example:

With a Mosaic "Forget me not"

Accept and wear this constant flower,

Thus copied out by art.

It blooms in Nature but its hour,--

For ever in the heart.

Affections into habits grown,--

Lives fastened in one lot,--

The flower has strengthened into stone

We name "Forget me not."
