⁂ The first mentioned is a lesser-known contribution to early theories of disease, notable for its attempt to explain epidemics through analogy and speculation rather than the emerging science of germ theory. Whilst not scientifically rigorous by modern standards, the book offers a glimpse into a time when ideas about disease were shifting—from the old belief in "bad air" to the early understanding of microbes.
