are numerous humorous collective nouns for different professions, such as a "diligence of messengers", a "melody of harpers", a "blast of hunters", "a subtlety of sergeants", "a gaggle of women", and a "superfluity of nuns". The tradition of a large number of such collective nouns which has survived into modern Standard English ultimately goes back to this book, via the popular 1595 edition by Gervase Markham in his The Gentleman's Academic. Angling A work added to the 1496 edition of the Book, was the Treatyse of Fysshynge with an Angle, on angling. It is an earlier collection of practical advice for fishing; and was drawn on by Isaak Walton. Among recognised sources for Walton's Compleat Angler are works of William Gryndall (1596) and Leonard Mascall (1590), both of which are close derivatives of the Treatyse. Heraldry The virtues of the gentleman, according to the Book, were skewed towards those useful in military terms. It contained a section on the law of heraldic arms, the Liber Armorum, reporting on the contemporary discussion on the relationship between gentility, and the heraldic practice of "gate-keeping" the grant of coats of arms (blazons). The Book took the line that the law of arms was part of the law of nature. James Dallaway reprinted this Book of Arms in his 1793 Inquiries into the Origin and Progress of Heraldry in England. The Book proposed that there could be several kinds of gentlemen: those "of blood" differed from those granted coat armour. J. P. Cooper wrote: The Boke's classification of gentry was to be repeated by heraldic writers for two centuries and was systematised by Ferne and Legh under Elizabeth. He takes as sources for the assertions in the Boke the works of Nicholas Upton called De Studio Militari, and the unpublished manuscript of readings in heraldry, around 1450, known as "Richard Strangways's Book" (i.e. BL Harley Collection 2259). There are idiosyncratic ideas on the curse of Ham underpinning the theory, with Europeans being "Hamitic"; Cooper believes the source may be the Testament of Love of Thomas Usk. Jacob's suggestion of another source for the work, a Book of the Lineage of Cote Armour, does not come with direct indications of the affiliation. Derivative works Gervase Markham edited the Book as The Gentleman's Academie, or the Booke of S. Albans (1595), London (for Humfrey Lownes). This was then reprinted in 1614 as A Jewel for Gentry.
