APPENDIX I ACCOUNTS OF EARLY WRITERS, NAVIGATORS AND OTHERS ALLUDED TO BY GILBERT AND NOT ALREADY DISPOSED OF THROUGHOUT THIS "BIBLIOGRAPHICAL HISTORY" Abano, PIETRO DI-Petrus Aponus, Apponensis or Apianus— called "the Reconciler" (1250-1316), was Professor of Medicine at Padua and wrote several works of importance on different subjects. The best known is "Conciliator differentiarum philosophorum ac Medicorum," which is devoted to the reconciliation of the various medical and philosophical schools, and in which reference is made to the loadstone, as is also the case in his "Tractatus de Venenis," published during 1490.

" Agricola, Georgius-Bauer-Landmann—(1494-1555), is called by Dr. Thomas Thomson one of the most extraordinary men as well as one of the greatest promoters of chemistry that have ever existed, and he pronounces Agricola's "De Re Metallica," which was published in 1546, 1556, 1558, 1561, as, beyond comparison, the most valuable chemical work produced in the sixteenth century. Agricola is also the author of "De Natura eorum," of " De Natura fossilium" and of "De veteribus et novis metallis," all published at Basle in 1657. Gilbert mentions Agricola in his De Magnete (Book I. chaps. i. ii. vii. viii.; Book II. chap. xxxviii.) and, in connection with him, alludes more particularly to Gilgil, the Mauretanian, and also to Christoph-Entzelt-Encelius, author of a book bearing the same name as Agricola's chief work, "De Re Metallica," published at Frankfort, 1551. Attention may as well be called here to additional authors, whose works, in the same line, are of great variety and LANE LIBRARY.

Agrippa, Heinricus Cornelius-ab Netiesheyem, Nettesheim— (1486-1535), German Doctor of Medicine, also a Doctor of Divinity, a soldier-knighted for valour on the battle-field of Ravenna—a diplomatist, an astrologer, etc. He was in turns, ambassador at Paris and London, historiographer to Emperor Charles V, professor at the university of Pavia, town physician in Friburg, private practitioner at Geneva, court physician to Louise of Savoy, chief magistrate of Metz, theological delegate to the schismatic council of Pisa, etc., and for three years was engaged in a military expedition to Catalonia. He is the author of several important works, the full collection of which was published at Lyons in 1550. The one by which he is best known is "De occulta philosophia," which was translated in French by Levasseur. REFERENCES.-Morley (Henry), The Life of H. Corn.

Amatus Lusitanus. See Lusitanus Amatus. Anaxagoras, born at Clazomenæ, one of the Greek towns of Ionia, in 500 B.C., three years before the death of Pythagoras, was a very eminent philosopher of the Ionic school, wherein he succeeded Anaximenes as a leader, and numbered among his many hearers and pupils Diogenes of Apollonia, Pericles, Euripides, Socrates and Archelaus. A very good analysis of Anaxagoras' philosophical opinions is to be found in the "Biographical Dictionary of the Society of Useful Knowledge." Gilbert alludes to him (De Magnete, Book II. chap. iii. and Book V. chap. xiii.) as believing that the loadstone was endowed with a sort of life, because it possessed the power of moving and attracting iron, and as declaring in fact that the entire world is endowed with a soul. Anaxagoras is accused, by Pliny and other early writers, of having predicted the fall of aerolites from the sun, and of regarding all bodies in the universe "as fragments of rocks, which the fiery ether, in the force of its gyratory motion, has torn from the earth and converted into stars (Humboldt, "Cosmos," 1859-1860, Vol. I. pp. 133-135, note; Vol. II. p. 309; Vol. III. pp. 11-12; Vol. IV. pp. 206-207). " Aristotle also attacks Anaxagoras for not properly etymologizing the word aether, from aï0ew, to burn, and on this account using it for fire. He shows that aether, which signifies to run perpetually, implies that a perpetual motion and perpetuity of subsistence belongs to the heavenly bodies ("Treatises of Aristotle," by Thos. Taylor, London, 1807, p. 43, note). According to Anaximenes, named above (born at Miletus about 528 B.C.), the primal principle was Aer, of which all things are formed and into which all things are resolved. He belonged to the branch called the dynamical, whose doctrines as to the heavenly bodies were opposed to those of mechanical philosophers such as Anaxagoras, Empedocles and Anaximander of Miletus ("Engl. Cycl.," Biography, 1866, Vol. I, p. 201), " References.-Houzeau et Lancaster, "Bibl. Gén.,” Vol. I. part i.

Aquinas St. Thomas-also called Doctor Angelicus (born at Aquino in Naples, A.D. 1225)-"the most successful organizer of knowledge the world has known since Aristotle "-was a famous schoolman and is considered by many the greatest of Christian philosophers. He is well worthy the profound respect and high admiration in which he is held always by Gilbert, who alludes to him in Book I. chap. i. and in Book II. chap. iii. of his De Magnete. The chief work of St. Thomas Aquinas is the "Summa Theologiæ," to which he devoted the last nine years of his life and which by many has been called the supreme monument of the thirteenth century. The first part of the "Summa Theologiæ Summa Theologiæ " is said to have been originally published in 1465 and the second part in 1471, the completed work first appearing during the year 1485.1 One of his critics remarks that those wishing to thoroughly comprehend the peculiar character of metaphysical thought in the Middle Ages should study Aquinas, in whose writings it is seen with the greatest consistency. He is thus spoken of in Dr. Wm. Turner's "History of Philosophy," published by Ginn & Co., 1903: He had a comprehensiveness of purpose which, in these modern times, seems nothing short of stupendous. It is only when, as we study the history of later scholasticism and the history of the philosophy of modern times, we shall look back to the thirteenth century through the perspective of ages of less successful attempts at philosophical synthesis, that we shall begin to realize the true grandeur of the most commanding figure in the history of mediæval thought." 1 In the Summa of Theology was presented, says Ozanam Antoine Frédéric, a vast synthesis of the moral sciences, in which was unfolded all that could be known of God, of man and of their mutual relations-a truly Catholic philosophy. . . Sixtus of Sienna and Trithemius both declare that St. Thomas explained all the works of Aristotle and that he was the first Latin Doctor who did so ("Christian Schools and Scholars," p. 81). It may also be added that, in the estimation of one of his biographers, the greatest of the many disciples of St. Thomas was, by far, Dante Alighieri, in whose "Divina Commedia" the theology and philosophy of the Middle Ages, as fixed by St, Thomas, have received the immortality which poetry alone can bestow, |
