In a secret meeting of the Katipunan by a small creek named Bitukang Manok (later known as Parian Creek, now nearly extinct) near Pasig on May 4, 1896, Bonifacio and his councilors decided to seek the advice of Rizal regarding a decision to revolt. Bonifacio delegated Dr. Pío Valenzuela as the Katipunan's emissary to Dapitan. This was done in order to inform Rizal of Katipunan's plan to launch a revolution and, if possible, a war against Spain. By the end of May 1896, Valenzuela had visited and interviewed Rizal in Dapitan. As cover, Valenzuela was accompanied by a blind man named Raymundo Máta, since Rizal is an ophthalmologist.
