The _Kanun-nameh_ of Suleiman, collected by the _Mufti_ Ebu su’ud, who died in 1574, contained a number of the Sultan’s _Kanuns_ relating mainly to financial and feudal matters. A translation of the incomplete table of contents of the Turkish manuscript copy of this _Kanun-nameh_ (which is in the Imperial Library at Vienna, Fluegel No. 1816) is given above as Appendix III. Many of the _Kanuns_ are translated in Hammer’s _Staatsverfassung_, pp. 396-424, where they are erroneously attributed to Achmet I. A little anonymous book, _The Policy of the Turkish Empire_, published at London in 1597, contains an interesting preface. The remainder of the book deals only with the Turkish religion, and is drawn mainly from Menavino, with some incorporation from Spandugino and Georgevitz. At the conclusion of Richard Knolles’s _Generall Historie of the Turkes_ (London, 1603), is to be found “A Briefe Discourse of the Greatnesse of the Turkish Empire,” written probably in the year of publication, since the story comes down to the accession of Achmet I in 1603. The lands of the empire, “of all others now upon earth farre the greatest,” are described, its revenues are set forth, the Timariotes, the Janissaries, the chief officers of state, and the fleet receive notice, and the Turkish power is compared with that of all states which touch its frontiers. It is to this part of Knolles’s work (as printed in the 6th edition of his History, with Ricaut’s continuation, London, 1687, ii. 981-990) that most of the references in the foregoing pages are made. Pietro Della Valle, known as Il Pellegrino, or The Pilgrim, wrote _Viaggi ... in la Turchia, la Persia, e l’India_, which was published in two volumes (four parts) at Rome in 1658-1663. He was in Constantinople in 1614 and 1615, and took advantage of every opportunity to witness a ceremony. Observant of costumes and jewels, he could not esteem the Turkish officials highly, because they were all slaves. The references in this treatise are to the second edition of the first part, published in 1662. Many collections based on the above-mentioned writings and on others were issued after the middle of the sixteenth century, and many surveys of the Ottoman Empire were prepared as time went on. Of the latter, three stand forth as of sufficient importance to throw light on sixteenth-century conditions:—
