Saint Lucy’s Day is December 13, which used to coincide with the Winter Solstice.  “Lucy” is derived from the Latin word for light, and Saint Lucy’s Day is celebrated as a festival of light in Scandinavian countries.. Here is John Donne’s great poem about dark and light, loss and love, death and rebirth.

‘Tis the year’s midnight, and it is the day’s,
Lucy’s, who scarce seven hours herself unmasks;
The sun is spent, and now his flasks
Send forth light squibs, no constant rays;
The world’s whole sap is sunk;
The general balm th’ hydroptic earth hath drunk,
Whither, as to the bed’s-feet, life is shrunk,
Dead and interr’d; yet all these seem to laugh,
Compared with me, who am their epitaph.

Study me then, you who shall lovers be
At the next world, that is, at the next spring;
For I am every dead thing,
In whom Love wrought new alchemy.
For his art did express
A quintessence even from nothingness,
From dull privations, and lean emptiness;
He ruin’d me, and I am re-begot
Of absence, darkness, death—things which are not.

All others, from all things, draw all that’s good,
Life, soul, form, spirit, whence they being have;
I, by Love’s limbec, am the grave
Of all, that’s nothing. Oft a flood
Have we two wept, and so
Drown’d the whole world, us two; oft did we grow,
To be two chaoses, when we did show
Care to aught else; and often absences
Withdrew our souls, and made us carcasses.

But I am by her death—which word wrongs her—
Of the first nothing the elixir grown;
Were I a man, that I were one
I needs must know; I should prefer,
If I were any beast,
Some ends, some means ; yea plants, yea stones detest,
And love; all, all some properties invest.
If I an ordinary nothing were,
As shadow, a light, and body must be here.

But I am none; nor will my sun renew.
You lovers, for whose sake the lesser sun
At this time to the Goat is run
To fetch new lust, and give it you,
Enjoy your summer all,
Since she enjoys her long night’s festival.
Let me prepare towards her, and let me call
This hour her vigil, and her eve, since this
Both the year’s and the day’s deep midnight is.
