from all parts of Spain to consult him. Rather late in life he wrote two treatises—one on the treatment of wounds, as well as on ulcers and syphilis, and another on the management of fevers. These two works were published at Antwerp, in the year 1574, as a single volume, the author being at that time, despite his advanced age (eighty), still in vigorous health and able to practice with skill both branches of the science of medicine. In 1658 a second edition of Arceo's two treatises was published at Amsterdam; and even at an earlier date there were published an English translation (1588) and a German version (1614). A perusal of the chapter which he devotes to the treatment of clubfoot gives the impression that Arceo was an excellent surgeon—eminently practical in his choice of means for securing certain results, and thoroughly familiar with the extent to which he might depend upon the powers of Nature to aid his efforts. The date of his death is not known.
Amatus Lusitanus is the name by which the Portuguese medical writer, Juan Rodriguez de Castel Bianco, is commonly known. He was born in the Province of Beira, Portugal, in 1511, of Jewish parents, and studied medicine at the University of Salamanca. After doing duty as a surgeon in two of the hospitals of that city, he took up his residence, for short periods of time, first in Antwerp and then in Ragusa, Dalmatia, on the eastern coast of the Adriatic. At this period of our history the Inquisition was extremely active throughout the domains that were under the rule of Charles the Fifth, and as a result Amatus soon found himself obliged to abandon all his books, instruments, etc., and flee for his life to Northern Greece. As the Turks, who were in possession of that country, were perfectly indifferent with regard to the religious beliefs of the Jews, Amatus was allowed to settle down quietly for the rest of his life at Thessalonica, in Macedonia.
During the later years of his career he published several books on topics relating to the science of medicine—two of them on materia medica and two on the cases of special interest which had come under his personal observation
