プラノ・カルピニ
According to Giovanni da Pian del Carpine, Batu was "kind enough to his own people, but he is greatly feared by them. He is, however, most cruel in fight; he is very shrewd and extremely crafty in warfare, for he has been waging war for a long time." William of Rubruck described him as about the height of his lord John de Beaumont and his entire face was covered with reddish spots.
