Plague without rats: The case of fifteenth-century Iceland
In the fifteenth century Iceland was ravaged by two epidemics which usually have been identified as plague. It is shown here that these epidemics were no less lethal than the Black Death in Europe. The first one probably killed half the population or more and persisted in the country for at least a year and a half. Since, for several reasons, it can safely be assumed that Iceland was not populated by rats at this time, this may offer the strongest available proof that an epidemic like the Black Death was not dependent on rats for its dissemination.
