* Writers of plays in Shakespeare's time didn't call themselves playwrights. They called themselves poets.

Shakespeare mostly wrote his plays in poetry. Mostly, but not entirely.

At the beginning of "As You Like It," all the characters speak prose, including Rosalind and Orlando, who haven't met yet.

A little bit after Rosalind and Orlando meet, they and everyone else start speaking in poetry.
