Analysis of Rubies

They brought me rubies from the mine,
And held them to the sun;
I said, they are drops of frozen wine
From Eden's vats that run.

I looked again,--I thought them hearts
Of friends to friends unknown;
Tides that should warm each neighboring life
Are locked in sparkling stone.

But fire to thaw that ruddy snow,
To break enchanted ice,
And give love's scarlet tides to flow,--
When shall that sun arise?
