What is the form?

Dar.Two roses newly plucked

Should each in turn be cast upon the earth;

Then, as each rose is thrown, pronounce the name

Of him whose mortal self it typifies.

Here are two roses plucked from yonder tree.

Sel. (taking them). Well then, fair rose, I name thee Ethais!—

Go, send thy mortal namesake to our cloud; (throws rose to earth).

’Tis done; conceal yourselves till they appear!
