Within each of these sections, the principle of arrangement, where it exists at all, is very loose; and either the compilation was carelessly made at first, or it has been considerably disordered in transcription. Sometimes a number of epigrams by the same author succeed one another, as though copied directly from a collection where each author's work was placed separately; sometimes, on the other hand, a number on the same subject by authors of different periods come together.[5] Epigrams occasionally are put under wrong headings. For example, a dedication by Leonidas of Alexandria is followed in the /Dedicatoria/ by another epigram of his on Oedipus;[6] an imaginary epitaph on Hesiod in the /Sepulcralia/ by one on the legendary contest between Hesiod and Homer;[7] and the lovely fragment of pastoral on Love keeping Thyrsis' sheep[8] comes oddly in among epitaphs. The epideictic section contains a number of epigrams which would be more properly placed in one or another of all the rest of the sections; and the /Musa Stratonis/ has several which happily in no way belong to it. There is no doubt a certain charm to the very confusion of the order, which gives great variety and unexpectedness; but for practical purposes a more accurate classification is desirable. The Anthology of Planudes attempts, in a somewhat crude form, to supply this. Each of the six books, with the exception of the {Erotika}, which remain as is in the Palatine Anthology, is subdivided into chapters according to subject, the chapters being arranged alphabetically by headings. Thus the list of chapters in Book I. begins, {eis agonas}, {eis ampelon}, {eis anathemata}, {eis anaperous}, and ends {eis phronesin}, {eis phrontidas}, {eis khronon}, {eis oras}.
