Welcome, and thank you for editing the article on Filippo Brunelleschi. Perhaps it was an experiment; if so, the best way to do tests in the future would be to use the sandbox. Anyway, I have reverted the article to an earlier version. If you would like to make many future contributions to Wikipedia articles, there are many advantages to creating an account.
