... Jerome Froben had accommodated us with a Greek _Euripides_ which now, as is right, he wants back. Still he holds out the hope that he will be able to buy a copy from Curio, and so I send three florins that he may buy one there and may bind it in place of the one I have.... We gladly send him this copy of his and he can give the money to his father for the Greek books which he promised to let us have for ten florins. September 8, 1521. John Froben sent me as a gift some time ago the _Complaint_ of Hutten, the Apostolic man (for the man is a bubble) whom Eck cudgelled. The following letter from Froben himself is interesting as indicating the personal relation borne by the publisher to certain of his publishing undertakings: _John Froben to his friend Zwingli._ Just as I was about to publish the little book of C. Cornelius Tacitus upon the customs and locations of the Germanic tribes, a friend [Beatus Rhenanus] showed me a brief commentary which he had prepared stating who now live in the locations described by Tacitus. This seemed to me to be a good idea, as it is a mistake to confine one’s reading to the more ancient authors to the neglect of those less remote. Think of the changes which have occurred since Cæsar’s day! Therefore, while his _Commentaries_ are worthy of the highest praise in point of truthfulness and style, yet it is necessary to read also Spartianus, Vopiscus, Trebellius Pollio, Ammianus Marcellinus, and Eutropius Procopius. Surely, if Cæsar were to return from the shades, he would scarcely recognise his former localities. The races have become so mixed, the population so changed, partly through destruction and partly through transplanting, that I may say all things are different. Because I know that you interrupt your higher studies to nibble on tit-bits of this description, I dedicate to you this commentary, which students will find useful. Thus light has been shed upon antiquity by the labours of the Swiss scholars, two of whom should especially be mentioned, Henricus Glareanus, my dear friend, and Joachim Vadianus, whose notes upon Pomponius Mela, I am happy to report, have received the applause of all the learned. Farewell. BASEL, 1519.
