[Someone sings in the street below]

Seize then thy gladness ere it turns to dust,

Youth can make all acts lovely, all deeds just;

Heed not the tyrant, lean Morality,

But steer thy passion down to the purple sea,

Through winding hills where Beauty hath her home

And calls to travellers, until thou come

Unto the Deep of Lovés Satiety.

[Leonardo da Vinci speaks]

Ha-ha, my passion to the purple sea!
