I felt a spirit of love begin to stir
Within my heart, long time unfelt till then;
And saw Love coming towards me fair and fain
(That I scarce knew him for his joyful cheer),
Saying, 'Be now indeed my worshipper!'
And in his speech he laughed and laughed again.
Then, while it was his pleasure to remain,
I chanced to look the way he had drawn near,
And saw the Ladies Joan and Beatrice
Approach me, this the other following,
One and a second marvel instantly.
And even as now my memory speaketh this,
Love spake it then: 'The first is christened Spring;
The second Love, she is so like to me.'
Dante Alighieri
