Those who wish to follow these inquiries must consult Dr. Creighton's book. Suffice it to say here that the author is of opinion that suspicion falls justly upon the foreign mercenaries who landed with Henry Tudor at Milford Haven on the 6th of August 1485 as the carriers of the disease.[183]
Dr. Creighton found among the British Museum manuscripts (Addit. MSS., No. 27, 582) a treatise on the _Sudor Anglicus_, or English Sweat, dedicated to Henry VII. by the author, Thomas Forrestier, M.D., a native of Normandy, who lived for a time in London. Stow says that the sickness began in London on the 21st September, and continued till the end of October, 'of the which a wonderful number died'; but Forrestier gives the date as the 19th.
The second sweat was in 1508, when many died in the city. In August public prayers were made at St. Paul's on account of the plague of sweat. The third epidemic was in 1517, and the fourth in 1528. On the 5th of June of the latter year, Sir Brian Tuke wrote to Bishop Tunstall that he had fled to Stepney 'for fear of the infection,' a servant having died in his house. Anne Boleyn, her brother George and her father caught the infection and recovered. Her brother-in-law, William Cary, died at Hunsdon. A large number of persons caught the disease, but a very considerable proportion recovered.
The fifth and last outbreak was in 1551, and it is interesting to note that Dr. John Caius, the famous physician, wrote a treatise on it. Dr. Norman Moore[184] describes this as 'the first original treatise published in England, by which I mean the first treatise in which the modern idea of observing the disease and writing a complete account of what was actually seen was carried out.'
In Machyn's _Diary_ it is said that 'there died in London many merchants, and great rich men and women, and young men and old of the new sweat'; and Sir Thomas Speke and Sir John Wallop are instanced among others. Hancocke, a minister of Poole, Dorset, refers to 'the posting sweat that posted from town to town thorow England, and was named "Stop-gallant," for it spared none. For there were some dancing in the Court at nine o'clock that were dead at eleven.'
In taking stock of diseases and epidemics in London, we may note that many of the pestilences previous to the Black Death were due to famine. Dr. Creighton says of the year 1258 that 'so great was the pinch in London from the failure of the crops and the want of money that fifteen thousand are said to have died of famine and of a grievous and widespread pestilence that broke out about the Feast of the Trinity, 19th May.' The number is that given by Matthew Paris, and Dr. Creighton adds: 'It suggests a larger population in the capital than we might have been disposed to credit. The same writer says that London was so full of people when the Parliament was sitting in the year before (1257) that the city could hardly hold them all in her ample bosom. The Annals of Tewkesbury put the whole mortality from famine and fever in London in 1258 at 20,000, but the whole population did not probably exceed 40,000.'[185]
