In Egypt and in Syria violent earthquakes took place, and in China they became from this time more and more frequent; for they recurred, in 1344, in Ven-tcheou, where the sea overflowed. A dreadful earthquake was experienced at Lisbon, where vast numbers of the inhabitants perished by the falling of the buildings. A.D. 1345, in Ki-tcheou, and also in both the following years in Canton, great commotions were experienced, especially subterraneous thunder. Meanwhile floods and famine devastated various districts until 1347, when the fury of the elements subsided in China. Whilst pestilence was thus raging, China, Syria, Greece, Egypt, Asia, and Africa suffered from it, A.D. 1346; and the year following, 1347, a pestilence similar to that which subsequently committed such ravages in the south of Gaul, Spain, and England (1348), raged in Italy and Sicily. 1345. Guido de Gaullaco informs us that in Spain, in the month of March, there broke out a pestilence, which he affirms spread all over the world, leaving scarcely a fourth part of the human race alive. Andres Laguna, Martinez de Leyva, Duarte Nunhez, and other medical writers, speak with horror and astonishment of this terrific plague, which, they say, lasted five years. Abu Giaphar Ahmed Ebn Ali Ebn Khatemar, a native of the city of Almeria, and one of the Arabian physicians, who, according to Casiri, was instructed in the history of the great pestilences, which nearly the entire world suffered from in the years of the Egira 748, 749, and 750, or of the Christian epoch 1347–48 and 1349, quotes the following passage: “The pestilence first broke out in Africa, whence it extended through all parts of Egypt and Asia, and finally attacked Italy, France, and Spain; but in the city of Almeria, where it raged with great malignity, it lasted nearly eleven months, namely, from the beginning of the month Rabiu, the first month of the year of the Egira 749, and of the Christian epoch 1348, until the commencement of the following year.” The work which contains the description of this pestilence consists of ten chapters, and is entitled ‘Morbi in posterum vitandi Descriptio et Remedia.’ Don Miguel Casiri makes mention of it in his Codex of the year 1780. Abu Abdalla Mohamed Ben Alkhatrib, a native of Granada and brother of the other Alkhatrib, also wrote a work on the causes and cure of the pestilence that affected the city of Granada in the year of the Egira 749, and of our Lord 1348, entitled ‘Quæsita de morbo horribili perutilia;’ and Casiri alludes to this work also in his Codex.
