Ancient Meitei science and technology
Yangtoupa (Yangdouba) and Yangtoupi (Yangdoubi) are the god and the goddess of time in Meitei mythology, folklore and religion (Sanamahism) of Ancient Manipur (Antique Kangleipak). The earliest known record of the existence of the cult of the two time controlling deities dates back to the 2nd century AD during the reign of King Khuyoi Tompok (aka Khuiyoi Tompok). The wooden statues of the two deities are the first known sculptures ever created.
