Which of the following is the source for Shakespeare's play Romeo and Juliet?

1. A French translation of an Italian poem

2. An English translation of a French translation of an Italian poem

3. The myth of Venus and Adonis

Shakespeare's primary source for Romeo and Juliet was a poem by Arthur Brooke called The Tragicall Historye of Romeus and Iuliet.

I personally think Shakespeare stole most of the ideas from the author of Romeus and Iuliet.
