Demetrius begat George, in the yeere 1237. was slaine by one Bathy, a Tartarian duke, which Bathy wasted Moscouia, and subdued the same vnto himselfe. Since which time the Russians were tributary to the Tartars, and were gouerned by such dukes as they pleased to set ouer them. Howbeit the Tartars so greatly abused that authoritie, that when they sent their ambassadours vnto the prince of Moscouie, he was constrained to goe forth and meete with them, and (as Herbortus Fulstinius in his Polonian historie reporteth) to offer them a bason full of mares milke, and if they had spilt any whit thereof vpon their horses maines, to licke it off with his toung, and hauing conducted them into his princely court, to stand bareheaded before them while they sate downe, and with all reuerence to giue eare and attendance vnto them. But by what meanes they shooke off at the length this yoake of seruitude, I will forthwith declare. About the same time almost all Polonia, and the dukedome of Silesia were ouerrun by the Tartars with fire and sword. Who hauing burnt Presla the chiefe citie of Silesia, and being come before the citie of Legnitz, they fought there a most cruel and bloody field, wherin was slain Duke Henrie himselfe being sonne vnto the most holy and deuout lady Heduice, with many others, whose monuments and graues be as yet extant in sundry places, and with an infinite multitude of common souldiers, insomuch that the Tartars filled nine great sackes with the eares of them which they had slaine. The Tartars to the end they might obtaine the victorie, presented vnto the view of our souldiers the portrature of a mans head placed by arte magique vpon a banner, wherein the letter X. was painted, which being shaken and mooued vp and downe breathed foorth a most loathsome stench, and strooke such a terrour into the hearts of our men, that being as it were astonished with the snaky visage of Medusa, they were vtterly daunted and dismayed. From thence Bathy and his company with the same bloodthirstie intent marched into Hungarie, and had almost slaine king Bela the fourth, who together with his sonne escaping by flight did scarcely ridde themselues out of the enemies hand. And when the whole world almost was exceedingly terrified at the cruel inuasions of this most barbarous nation, at length Pope Innocentius the fourth sending ambassadours [Marginal note: These ambassadours were Iohan. de Plano Carpini and Frier Benedict a Polonian.] vnto Bathy obtained peace for fiue yeeres: but to forsake his heathenish superstitions and to become a Christian, he would by no meanes bee perswaded. For he was by the instigation of the Saracens infected with deuilish opinions of Mahomet, as being more agreeable vnto his barbarous rudenes, which euen vnto this day the Tartars do maintaine, like as the prophane Turkes also.
