I'm going to have to defend myself here against calumnious suggestion that I might have broken the rules I believed I knew the answer, unfortunately incorrectly, and simply used google to try and confirm my thoughts. Having learnt that I was probably incorrect I didn't go on to attempt to find the correct answer. Therefore I believe, your honour, that I acted within the spirit and letter of the law.

And while I'm here being petty and pedantic... The earlier answer should have been the Trevi Fountain, not the Trivi.
