Lines from Ulysses: "In sleep the wet sign calls her hour"

She was born for water, I for tides;
               To make a seed, you first must grow a flower
She became the second of my brides.
               In sleep the wet sign calls her hour.

And now I have a third, I call her Keb;
               To make a seed, you first must grow a flower
A Saggitarius to a Cancer wed...
               In sleep the wet sign calls her hour.
