The account books of Plantin have been preserved, giving the records of his undertakings during the larger portion of his business activity. Among the entries of disbursements which have an interest for readers of to-day are those recording the payments for editorial service or for other literary work. In a number of cases, these payments, whether to authors or to editors, were made in the shape of copies of the book on which the work had been done. Thus, Jean Isaac received, in 1554, in full for the copyright of his Hebrew Grammar, a hundred copies of the book, while, in the year following, he was paid for his abridgment of the Hebrew Dictionary of Pagnino, the sum of fifteen crowns. Dodonaeus, in 1565, accepted fifty copies of his _Frumentorum Historia_ (which had been a very expensive work to produce). Hunnaeus, in 1566, was given two hundred copies of his _Dialectica_. Pierre de Savonne, for a treatise on book-keeping, was paid, in 1567, forty-five florins and one hundred copies; Guicciardini, for a Description of the Poetry of the Low Countries, received eighty-two florins and fifty copies. Stadius, for his _Commentaries_ on Florus, was paid, in 1567, twenty florins; Carrion, for editorial work on _Sallust_, fourteen florins; Venutius, for a Spanish translation of the _Theatrum Orbis_, was paid one hundred florins; while Everaert, for the translation into Flemish of Porta’s _Magia Naturalis_, received fifteen florins. The four theological professors of Louvain who revised the _Bible Française_, were paid each twenty-five florins.
