Rugs, particularly Oriental rugs, belong in a way to the same family as tapestry and may be classified with it. There is this difference, however: being less complicated in character and for the most part adorned only with geometrical patterns and rudimentary arabesques, rugs are imitated with greater facility. Things do not change so quickly in the East as in Western countries, and there the old weaving apparatus is still in use and materials are only just beginning to be imported from Europe. A large field is thus opened up to imitation, and to a certain extent to faking also. It is nevertheless hard to deceive experts and specialists. Keen-eyed and accustomed to distinguish between different kinds, and to judge of age, they are also able to detect modern frauds. But, alas, good experts are rare and conceited collectors abound, and for this reason fraud is rampant and remunerative, even in this field. Those buying rugs for the sake of having a collection and not to furnish their houses with a comfortable and highly artistic luxury are advised to place themselves in the hands of an expert. It will save time and trouble. An eclectic collector, however gifted, will rarely consent to go deeply into this branch, as the mastery of it implies great sacrifice of time and the boredom of learning a difficult language, things that prove no obstacle to the passionate lover of the speciality, but tedious and irksome to the general art lover. Following an erratic course in this chapter, we will now pass on to books, manuscripts and autographs, a branch with many devotees and all kinds of collectors, in which trickery and faking find an almost incredibly large sphere of action. Book collectors are of two kinds, the one who prizes the work for the rarity of the edition, and the other who is attracted by the binding. The former is the true book collector, the latter is really only a collector of rare and artistic bindings. The two preferences do not mutually exclude one another, of course, and when found together offer the most complete kind of book collector.
