Heeren undertook the history of classical literature--a great desideratum, which no one had attempted to supply. But, unfortunately, he has only given an introduction, carrying us down to the close of the fourteenth century, and a history of the fifteenth. These are so good, that we must much lament the want of the rest; especially as I am aware of nothing to fill up the vacuity. Eichhorn, however, is here of considerable use. In the history of mathematical science, I have had recourse chiefly to Montucla and, as far as he conducts us, to Kästner, whose catalogue and analysis of mathematical works is far more complete, but his own observations less perspicuous and philosophical. Portal’s History of Anatomy, and some other books, to which I have always referred, and which it might be tedious to enumerate, have enabled me to fill a few pages with what I could not be expected to give from any original research. But several branches of literature, using the word, as I generally do, in the most general sense for the knowledge imparted through books, are as yet deficient in anything that approaches to a real history of their progress. The materials of literary history must always be derived in great measure from biographical collections, those especially which intermix a certain portion of criticism with mere facts. There are some, indeed, which are almost entirely of this description. Adrian Baillet, in his Jugemens des Sçavans, published in 1685, endeavoured to collect the suffrages of former critics on the merits of all past authors. His design was only executed in a small part, and hardly extends beyond grammarians, translators, and poets; the latter but imperfectly. Baillet gives his quotations in French, and sometimes mingles enough of his own to raise him above a mere compiler, and to have drawn down the animosity of some contemporaries. Sir Thomas Pope Blount is a perfectly unambitious writer of the same class. His Censura Celebriorum Autorum, published in 1690, contains nothing of his own, except a few short dates of each author’s life, but diligently brings together the testimonies of preceding critics. Blount omits no class, nor any age; his arrangement is nearly chronological, and leads the reader from the earliest records of literature to his own time. The polite writers of modern Europe, and the men of science, do not receive their full share of attention; but this volume, though not, I think, much in request at present, is a very convenient accession to any scholar’s library.
