The Hospital was a characteristic institution of the Order, and deserves some mention. Originally the chief scene of their activities, the Hospital was never forgotten by the Knights. Their first duty, wherever they went, was always to build a Hospital to tend the sick, and to the end every Knight at the Convent, in theory at least, went to take his turn in attending at the Hospital for one day in the week. The site of the Hospital, on the south-east side of Valetta, has been condemned by science as unhealthy, and it is very easy with modern knowledge to find many faults in its organisation. Howard, in his "Lazarettos in Europe," in 1786, gave a vivid description of its condition and exposed its defects. At that time, however, the Hospital was sharing the general decadence of the Order, and discipline had become very lax. But, even so, the Hospital was far superior to most other hospitals in Europe and still kept much of that distinction it had acquired in the great days of the Order. We must remember that hospital organisation is a very recent science, and it would be unfair to accuse the Knights of neglecting what had not yet been discovered. Their Hospital was one of the most famous in Europe, and was used by many from Sicily and Southern Italy as well as by the natives of Malta. It was open to all who wished to use it, and the attendance of patients from a distance proved that it supplied a need. The hospital, which had generally over 400 invalids, was maintained at great cost to the Order, and the regulations were drawn up with great care, though they reveal an amazing ignorance of some fundamental laws of health. Patients, for instance, who were members of the Order received meals twice as large as other patients. [Footnote 1: So called because they were Knights "by right" of noble birth.] CHAPTER IV THE DECLINE 1565-1789. The history of the Order of St. John after the siege of Malta in 1565 is a sad story of gradual and inevitable decay. The magnificent heroism of the Knights at the siege raised their fame throughout Europe to the highest pitch, and the siege was rightly regarded as one of the first decisive checks received by the Ottoman conquerors. It is easy to imagine the anxious expectation of Europe in that summer of 1565, when the heretic Queen of England ordered prayers to be offered in the diocese of Salisbury for the safety of the Knights of St. John.
