Worshippers give a chicken as offering to Tenggerese shaman as they pray at Widodaren cave during the Tenggerese Hindu Yadnya Kasada festival on Aug. 11, 2014 in Probolinggo, Java, Indonesia. The festival is the main festival of the Tenggerese people and lasts about a month. On the fourteenth day, the Tenggerese make the journey to Mount Bromo to make offerings of rice, fruits, vegetables, flowers and livestock to the mountain gods by throwing them into the volcano's caldera.

The origin of the festival lies in the 15th century, when a princess named Roro Anteng started the principality of Tengger with her husband Joko Seger, and the childless couple asked the mountain Gods for help in bearing children. Ulet Ifansasti / Getty Images
