Riddle me this

Anton just showed me a poem they read in his 17th c. lit. course. See if you can tell me what the title and subject matter is.

There is a thing which in the light
Is seldom us'd, but in the night
It serves the maiden female crew,
The ladies, and the good-wives too:
They use to take it in their hand,
And then it will uprightly stand;
And to a hole they it apply,
Where by its good will it would die:
It spends, goes out, and still within
It leaves its moisture think and thin.

- Sir John Suckling, 1659

It's called "A Candle" you sickos.
