Lopburi (Lavo) is described in Book III of Marco Polo's "Travels", where it is called "Locach". This came from the Chinese (Cantonese) pronunciation of Lavo, "Lo-huk". The city is referred to as "Lo-ho" in chapter 20 of the History of Yuan (元史 : "Yuán Shǐ"), the official history of the Mongol, or Yuan Dynasty of China. Due to a scribal error in Book III of Marco Polo's travels treating of the route southward from Champa, where the name Java was substituted for Champa as the point of departure, Java Minor was 1,300 miles to the south of Java Major, instead of from Champa, on or near an extension of the Terra Australis. As explained by Sir Henry Yule, the editor of an English edition of Marco Polo's "Travels": "Some geographers of the 16th century, following the old editions which carried the travellers south-east of Java to the land of "Boeach" (or Locac), introduced in their maps a continent in that situation".
