NOTE 1.—­Friar William, of Tripoli, of the Dominican convent at Acre, appears to have served there as early as 1250. [He was born circa 1220, at Tripoli, in Syria, whence his name.—­H.  C.] He is known as the author of a book, De Statu Saracenorum post Ludovici Regis de Syria reditum, dedicated to Theoldus, Archdeacon of Liege (i.e.  Pope Gregory).  Of this some extracts are printed in Duchesne’s Hist.  Francorum Scriptores.  There are two MSS. of it, with different titles, in the Paris Library, and a French version in that of Berne.  A MS. in Cambridge Univ.  Library, which contains among other things a copy of Pipino’s Polo, has also the work of Friar William:—­“Willelmus Tripolitanus, Aconensis Conventus, de Egressu Machometi et Saracenorum, atque progressu eorumdem, de Statu Saracenorum,” etc.  It is imperfect; it is addressed THEOBALDO Ecclesiarcho digno Sancte Terre Peregrino Sancto.  And from a cursory inspection I imagine that the Tract appended to one of the Polo MSS. in the British Museum (Addl.  MSS., No. 19,952) is the same work or part of it.  To the same author is ascribed a tract called Clades Damiatae. (Duchesne, V. 432; D’Avezac in Rec. de Voyages, IV. 406; Quetif, Script.  Ord.  Praed. I. 264-5; Catal. of MSS. in Camb.  Univ.  Library, I. 22.)

NOTE 2.—­I presume that the powers, stated in this passage from Ramusio to have been conferred on the Friars, are exaggerated.  In letters of authority granted in like cases by Pope Gregory’s successors, Nicolas III. (in 1278) and Boniface VIII. (in 1299), the missionary friars to remote regions are empowered to absolve from excommunication and release from vows, to settle matrimonial questions, to found churches and appoint idoneos rectores, to authorise Oriental clergy who should publicly submit to the Apostolic See to enjoy the privilegium clericale, whilst in the absence of bishops those among the missionaries who were priests might consecrate cemeteries, altars, palls, etc., admit to the Order of Acolytes, but nothing beyond. (See Mosheim, Hist.  Tartar.  Eccles. App.  Nos. 23 and 42.)

NOTE 3.—­The statement here about Bundukdar’s invasion of Cilician Armenia is a difficulty.  He had invaded it in 1266, and his second devastating invasion, during which he burnt both Layas and Sis, the king’s residence, took place in 1275, a point on which Marino Sanuto is at one with the Oriental Historians.  Now we know from Rainaldus that Pope Gregory left Acre in November or December, 1271, and the text appears to imply that our travellers left Acre before him.  The utmost corroboration that I can find lies in the following facts stated by Makrizi:—­
