To the right and behind the Dusit Maha Prasat rises a strange model mountain, decorated with fabulous animals and topped by a castle and prang. It represents Mount Krailas, the Himalayan home of the Hindu god Shiva (Phra Isuan in Thai), and was built by Rama IV as the site of the royal tonsure ceremony, last held here in 1932, just three months before the end of the absolute monarchy. In former times, Thai children generally had shaved heads, except for a tuft or top-knot on the crown, which, between the age of eleven and thirteen, was cut in a Hindu initiation rite to welcome adolescence. For the royal children, the rite was an elaborate ceremony that sometimes lasted seven days, culminating with the king’s cutting of the hair knot, which was then floated away on the Chao Phraya River. The child was then bathed at the model Krailas, in water representing the original river of the universe flowing down the central mountain.
