Concerning the great rarity of this interesting tract, which was unknown to the Rev. A. Dyce when publishing his edition of Greene's works, your readers may see a notice by Mr. Collier in his _Extracts from the Registry of the Stat. Comp._, vol. ii. p. 233., apparently from the present copy, no other being known. THOS. CORSER. Stand Rectory. THE DUTCH MARTYROLOGY. (Vol. iii., p. 443.) Besides the copy of the above work mentioned by your correspondent J. H. T., several others are known to exist in this country. Among them I may mention one in the library of the Baptist College, Bristol. My own copy was supplied by a London bookseller, who has likewise imported several other copies from Holland, where it is by no means a scarce work. The second illustrated edition was published twenty years after the decease of Van Braght. The first edition, without engravings, now before me, appeared in 1660, which was the edition used by Danvers. But Danvers does not appear to have known its existence, when the first edition of his treatise came out in 1673. The "large additions" of his second edition in 1674, are chiefly made from the work of Van Braght. The original portion of Van Braght's work is, however, confined to the first part. The second part, _The Martyrology_, strictly so called, is of much earlier date. Many single narratives appeared at the time, and collections of these were early made. The earliest collection of martyrdoms bears the date of 1542. This was enlarged in 1562, 1578, 1580, and 1595. This fact I give on the authority of Professor Müller of Amsterdam, from the _Jaarboekje voor de Doopsgezinde Gemeenten in de Nederlanden, 1838 en 1839_, pp. 102, 103. An edition, dated 1599, of these very rare books is now before me. It has the following curious and affecting title: "Dit Boeck wort genaemt: Het Offer des Heeren, Om het inhout van sommige opgeofferde Kinderen Gods, de welcke voort gebrocht hebben, wt den goeden schat haers herten, Belijdinghen, Sentbrieuen ende Testamenten, de welcke sy met den monde beleden, ende met den bloede bezeghelt hebben, &c. &c. Tot Harlinghen. By my Peter Sebastiaenzoon, Int jaer ons Heeren MDXCIX." It is a thick 12mo. of 229 folios, and contains the martyrdoms of thirty-three persons (the first of which is Stephen), which were subsequently embodied in the larger martyrologies. Each narrative is followed by a versified version of it. A small book of hymns is added, some of them composed by the martyrs; and the letters and confession of one Joos de Tollenaer, who was put to death at Ghent in 1589.
