THE first Institutor of this Order was a wealthy Gentleman of Germany, who dwelt at Ieru∣salem after it was taken by the Christians, together with divers other men of his Country; and being exceed∣ing rich, kept an hospitable House, relieving all Passengers and Pilgrims that travelled to Ierusalem, insomuch that his House became (as it were) an Hospital: At length he built near unto his House a fair Church, which he dedicated to our Lady; and many Christians resorting thither, as well out of Devotion, as to visit the Sick, they resolved to erect a Fr••ternity; and having chosen a Great Ma∣ster for their Governor (which was about the Year of our Lord 1190.) they imitated the Knights Templars in their Military Employ∣ments, and the Knights Hospitallers in their Acts of Piety and Charity; and instituted several Orders to be observed amongst them, being much the same with those of the Knights Hospitallers and Templars, which were afterwards confirmed by Pope Celestine the Third: But their Habit was a white Man∣tle, and on the Breast thereof for their En∣sign they wore a black Cross voided with a Cross Potence.
The Holy Land being retaken from the Christians by the Sarazens, these Knights returned into Germany, where they had not continued long, ere they went to the Em∣peror Frederick the Second, and acquainted him that the people of Prusia (who were barbarous Idolaters) used Incursions upon the Confines of Saxony, and besought the Emperor's leave to make War upon them at their own Charges, but with this Con∣dition, that whatsoever they took should be theirs for the maintenance of the said Or∣der;
