In German there is a translation in full with good notes by W. E. Weber (Leipzig, Brockhaus, 1844). There is also a summary of the first book of the _Diritto universale_ by K. H. Müller, forming the first volume of a series of Vico's _Kleine Schriften_ which was not continued (Neubrandenburg, Brunslow, 1854).
The only English translation is a version of the book on Homer based on Michelet's French translation and inserted in H. Nelson Coleridge's _Introduction to the Study of the Greek Classic Poets_ (3rd ed., London, Murray, 1846).
[Footnote 1: By now (1913) the second volume has appeared: the third will appear next year.]
By way of supplement to the autobiography, Villarosa collected information on Vico's last years and published it as a continuation of that work in his edition of the _Opuscoli,_ vol. i. (1818).
This supplement, together with everything else that has been published in the way of documents or contemporary records of Vico, may be found collected in the fifth volume of the new edition of his works above mentioned (p. 307) and entitled: _L'Autobiografia, il carteggio e le poesie varie,_ ed. B. Croce (Bari, Laterza, 1911).
There are only three monographs on Vico which may still be read with profit (that of Ferrari, _La Mente del Vico,_ admirable editor though he was, may best be consigned to merciful oblivion); they are as follows:--
1. Carlo Cantoni, _G.B.V., studi critici e comparativi_ (Turin, Civelli, 1867). Cf. for certain reservations A. Faggi, in _Rivista filosofica italiana,_ vol. ix., 1906, pp. 593-606, and G. Gentile, in _Critica,_ vol. v., 1907, pp. 197-201.
2. Karl Werner, _G.B.V. als Philosoph und gelehrter Forscher,_ (Wien, Braumüller, 1881). Cf. _Zeitschrift für Philosophie und philos. Kritik,_ vol. lxxii., 1883, pp. 139-52.
3. Robert Flint, _Vico_ (Edinburgh and London, 1884). (Italian translation by F. Finocchietti, Florence, 1888).
See what has been said of these above, p. 277. Of short and general studies the following are the best:--
1. B. Spaventa, _G.B.V.,_ in _Prolusione è introduzione alle lezioni di filosofia_ (Naples, Vitale, 1862), pp. 83-102, reprinted under the title _La Filosofia italiana nelle sue relazioni con la filosofia europea,_ ed. G. Gentile (Bari, Laterza, 1908); see pp. 111-35 of this reprint.
