As though this complication were to become more involved, and the Kabbalistic-Messianic disorder were to be pursued to its utmost limits, a Sabbatian champion unexpectedly appeared in a man of European culture, not wanting in gifts, Abraham Michael Cardoso. He was an original character, a living personification of the transformation of the Portuguese Jews after their expulsion. Born of Marrano parents in a small town of Portugal, Celarico, in the province of Beïra, Miguel Cardoso, like his elder brother Fernando, studied medicine. While the latter devoted himself earnestly to science, Miguel dawdled away his days amidst the luxury of Madrid, sang love-songs with the guitar under the balconies of fair ladies, and paid very little heed to Kabbala or Judaism. What influenced him to leave Spain is not known. Perhaps his more serious and thoughtful brother, who, after making a name in Spain as a medical and scientific author, out of love to Judaism migrated to Venice, where he plunged deeply into Jewish literature, infected him with enthusiasm. Both brothers assumed Jewish names after their return to the religion of their forefathers. The elder, Isaac Cardoso, gave up his name Fernando; the younger took the name of Abraham in addition to that of Miguel (Michael). Both composed verses in Spanish. While the elder brother led a regular life, guided by moral principles and a rational faith, the younger fell under the sway of extravagant fancy and an eccentric manner of living. Isaac Cardoso (born 1615, died after 1680) conferred renown on Judaism, while Abraham Michael Cardoso (born about 1630, died 1706) was a disgrace to it. The latter lived as a physician at Leghorn, but not flourishing he accepted the position of physician in ordinary to the Bey of Tripoli. His warm-blooded, dissolute nature was a hindrance to his advancement. Contrary to the custom of African Jews, he married two wives, and instead of employing himself with his difficult science, he revolved fantastical schemes. Cardoso appears to have been initiated into the Kabbala and the Sabbatian delusion by Moses Pinheiro, who was living at Leghorn.
