voyagers had with them in the singing of their parting hymns at Leyden and Delfshaven, as mentioned by Winslow and in the earlier inventories:  These metrical versions of the Psalms constituted at the time, practically, the only hymnology permitted in the worship of the “Separatists,” though the grand hymn of Luther, “Ein feste Burg ist unser Gott,” doubtless familiar to them, must have commended itself as especially comforting and apposite.

Of the doctrinal tracts of their beloved Pastor, John Robinson, there is every probability, as well as some proof, that there was good supply, as well as those of Ainsworth and Clyfton and of the works of William Ames, the renowned Franeker Professor, the controversial opponent but sincere friend of Robinson:  the founder of evangelical “systematic theology,” [method—­Methodist?  D.W.] whom death alone prevented from becoming the President of Harvard College.  We may be equally sure that the few cases of books in the freight of the Pilgrim ship included copies of the publications of the “hidden and hunted press” of Brewster and Brewer, and some at least of the issues of their fellows in tribulation at Amsterdam and in Scotland and England.  Some few heavy tomes and early classics in English, Dutch, Latin, and Greek were also presumably among the goodly number of books brought in the may Flower by Brewster, Bradford, Winslow, Fuller, Hopkins, Allerton, Standish, and others, though it is probable that the larger part of the very considerable library of four hundred volumes, left at his death by Brewster (including sixty-two in Latin), and of the respectable libraries of Fuller, Standish, and others, named in their respective inventories, either were brought over in the later ships, or were the products of the earliest printers of New England.  One is surprised and amused that the library of the good Dr. Fuller should contain so relatively small a proportion of medical works (although the number in print prior to his death in 1633 was not great), while rich in religious works pertinent to his functions as deacon.  It is equally interesting to note that the inventory of the soldier Standish should name only one book on military science, “Bariffe’s Artillery,” though it includes abundant evidence to controvert, beyond reasonable doubt, the suggestion which has been made, that he was of the Romanist faith.  Just which of the books left by the worthies named, and others whose inventories we possess, came with them in the Pilgrim ship, cannot be certainly determined, though, as before noted, some still in existence bear intrinsic testimony that they were of the number.  There is evidence that Allerton made gift of a book to Giles Heale of the may-Flower (perhaps the ship’s surgeon), while the ship lay at Plymouth, and Francis Cooke’s inventory includes “1 great Bible and 4 olde bookes,” which as they were “olde,” and he was clearly not a book-buyer, very probably came with him in the ship.  In fact, hardly an adult of the Leyden colonists, the inventory of whose estate at death we possess, but left one or more books which may have been his companions on the voyage.
