The word "China" has been used in English since the 16th century; however, it was not a word used by the Chinese themselves during this period in time. Its origin has been traced through Portuguese, Malay, and Persian back to the Sanskrit word ''Chīna'', used in ancient India. "China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian ''Chīn'' (), which was in turn derived from Sanskrit ''Cīna'' (). ''Cīna'' was first used in early Hindu scripture, including the ''Mahābhārata'' (5th century BCE) and the ''Laws of Manu'' (2nd century BCE). In 1655, Martino Martini suggested that the word China is derived ultimately from the name of the Qin dynasty (221–206 BCE). Although usage in Indian sources precedes this dynasty, this derivation is still given in various sources. The origin of the Sanskrit word is a matter of debate, according to the ''Oxford English Dictionary''. Alternative suggestions include the names for Yelang and the Jing or Chu state.
