Brownrigg, an Englishman, who wrote a book on the means of preventing the plague, says, that quarantine was first established by the Venetians in the year 1484[1127], but like his learned countryman Mead, who assigns the same year, without adducing any proofs[1128]. I imagined that I should find some more certain information respecting this point in Le Bret’s History of the Republic of Venice; but as that historian does not mention, as the title professes, the original sources from which he derived his materials, his work is less worthy of credit. He tells us however that the grand council in 1348, chose three prudent persons, whom they ordered to investigate the best means for preserving health, and to lay the result of their inquiry before the council. The plague which broke out afterwards in 1478, rendered it necessary that some permanent means should be thought of, and on that account a peculiar magistracy consisting of three noblemen, with the title of sopra la sanità, was instituted in 1485. As these were not able to stop the progress of the disease, the painful office was imposed upon them, in 1504, of imprisoning people against whom complaints might be lodged, and even of putting them to death; and in 1585 it was declared, that from the sentence of these judges there should be no appeal. Their principal business was to inspect the lazarettos erected in certain places at some distance from the city, and in which it was required that all persons and merchandize coming from suspected parts should continue a stated time fixed by the laws. The captain of every ship was obliged also to show there the bill of health which he had brought along with him.
As Le Bret produces no proof that quarantine was established by the Venetians so early as he says, I cannot help suspecting that he is mistaken respecting the year (1348), and conjecture that it ought to be 1448, or perhaps 1484. I have not been able however to resolve my doubt; for, in examining different Italian writers, I find that various years are given[1129]. The institution of the council of health (sopra la sanità) is mentioned by Bembo; but I cannot discover from him to what year he alludes[1130]. His countryman Lancellotti, who undoubtedly must have understood him well, makes it to be 1491[1131]. Caspar Contarenus, who died in 1542, in the sixtieth year of his age, mentions no particular period, and only says that the institution had been formed not long before his time[1132]. The islands on which the pest-houses were erected, were called il Lazaretto vecchio and il Lazaretto nuovo. In the elegant description of Venice, ornamented with abundance of plates, below mentioned, it is remarked that the pest-house on the former island was built in 1423, and that on the latter in 1468[1133]. The same account is given in the newest and best Topography of Venice[1134].
The Venetians are entitled to the merit of having improved the establishments formed to prevent infection; and that their example was followed in other countries is generally admitted. But the year in which quarantine was first ordered by them to be performed is uncertain. Muratori[1135], following Lorenzo Candio, gives the year 1484, and Howard[1136] says that the college of health was instituted in 1448.
Brownrigg affirms that letters of health, in which he confides more than in quarantine, were first written in 1665 by the consuls of the different commercial nations, but they are much older, for Zegata[1137] asserts that they were first established in 1527, when the plague again made its appearance in Europe.
This much is certain, that all these means against infection, which, though far from being perfect, have secured Europe from this misfortune, were not invented or proposed by physicians, but ordered by the police, contrary to their theory. The latter seem to have known, at an early period, the most dangerous causes of infection, and to have formed at a very great expense precautionary means, the observance of which was enforced under pain of the severest punishment.
Why the space of forty days was chosen as a proof I do not know. It arose no doubt from the doctrine of the physicians in regard to the critical days of many diseases. The fortieth day seems to have been considered as the last or extreme of all the critical days; on which subject many physicians appear to have entertained various astrological conceits[1138]. On the Turkish frontiers this period was reduced under the emperor Joseph II. to twenty days[1139].
[With respect to the quarantine establishments in this country, Mc Culloch observes that they are exceedingly defective. Even in the Thames there is not a lazaretto where a ship from a suspected place may discharge her cargo and refit; so that she is detained, frequently at an enormous expense, during the whole period of quarantine, while if she have perishable goods on board, they may be very materially injured. The complaints as to the oppressiveness of quarantine regulations are almost wholly occasioned by the want of proper facilities for its performance. Were these afforded, the burdens it imposes would be rendered comparatively light.
The existing quarantine regulations are embodied in the act 6 George IV. c. 78, and the different orders in council issued under its authority. These orders specify what vessels are liable to perform quarantine, the places at which it is to be performed, and the various formalities and regulations to be complied with.]
FOOTNOTES
[1124] [This opinion is not generally admitted by the most experienced medical men in this country. It is a disputed point whether the plague is even contagious; and the mass of evidence is in favour of its being so occasionally, but that the plague is usually not propagated in this manner. The disappearance of this pest from our own and most other countries of Europe is undoubtedly owing to the much greater attention paid to drainage, ventilation, and the prevention of the accumulation of filth in the streets, &c. When the peculiar atmospheric conditions upon which its diffusion depends are present, quarantine has proved insufficient to prevent its propagation.]
