William of Rubruck
Less than 100 years later, an emissary was sent by Louis IX to the Mangu Khan in Karakorum in 1253. Friar William of Rubruck reported that the Tibetan people ‘were held an abomination among all nations’ due a ritual of drinking from the skulls of their parents. Friar William was also the first to describe a Tibetan lama's garments in detail.
