Note 327 — BOOK XI[327]

In the first part of book xi are contained the remnants of the sciences of human anatomy and physiology as the ancients had known them. The second part is devoted to unnatural births, which were regarded as having a prophetic meaning, and to monstrous races. It is not known what were Isidore’s immediate sources for bk. xi. Most of the natural science of the later Roman empire, however, was drawn ultimately from Pliny. To correspond to Isidore’s topics in this book of the Etymologies, comparative anatomy and physiology are found in Pliny’s Natural History, bk. xi, ch. 44 et seq., and chapters on monstrous races (Gentium mirabiles figurae) and on unusual and unnatural births (prodigiosi, monstruosi partus) are found in bk. vii.
