Carbonell must have known that the Black Death had much earlier reached his master’s possession of Majorca. In April 1348 Pedro IV instructed the Government of Majorca to take steps to prevent the further propagation of the disease.{213} This not very helpful instruction does not seem to have been observed with any success. One chronicler puts the death roll at fifteen thousand in a single month and other writers suggest that the total loss was at least twice that figure and up to eighty per cent of the total population.{214} On 3 May the Government of Majorca were complaining that the island was so weakened by disease that it could no longer protect itself against the attacks of pirates and the Bey of Tunis. They appealed for help from the mainland. Pedro IV agreed to send some galleys but, with the characteristic pawkiness of a central government, insisted that Majorca pay half the cost. By June 1349 the Governor of Majorca found himself in his turn instructed to send troops to defend the still worse depopulated Minorca against probable enemy attack.
The Mediterranean coast of Spain was quickly affected. Barcelona and Valencia were both struck by the plague in May 1348, and Almeria in June. Ibn Khātimah, the Arab physician, who was living in Almeria at the time, says that the first case arose in a house in the poor quarter of the town belonging to a family called Beni Danna.{215} The plague took an unusually protracted course, lasting through the autumn and winter and still being active when Ibn Khātimah wrote his record in February, 1349. Even at its peak it was not killing more than seventy people a day in a population that must have been in the neighbourhood of twenty thousand.
The disease spread next through Arab Spain so that the armies confronting Alfonso XI were afflicted before their Christian enemies. It is said that the Arabs were deeply disturbed by this phenomenon and many of them seriously thought of adopting Christianity as a form of preventive medicine. Fortunately for their faith, however, the Black Death was soon raging quite as disastrously among the troops of Castile. ‘When they learned that the pestilence had now reached Christian men their good intentions died and they returned to their vomit.’{216} The Castilian army in front of Gibraltar survived inviolate through 1349; then, in March 1350, was suddenly attacked by the plague. The senior officers begged King Alfonso to leave his troops and seek safety in isolation but he refused to do so. He duly caught the disease and died on Good Friday, 26 March 1350. He was the only ruling monarch of Europe to perish during the Black Death.
But the royal house of Aragon did not escape unscathed. King Pedro lost his youngest daughter and his niece in May, and his wife in October. By the autumn order seemed to be breaking down in his dominions. Bands of armed brigands were straying over the countryside and an ordinance had to be published ordering severe punishment for any one found looting the houses of plague victims. Li Muisis records the experiences of a pilgrim to St James of Compostella who passed through Salvatierra on the way home.{217} The town had suffered so grievously from the plague that not one citizen in ten remained alive (a characteristically woolly estimate which,
