The bones resembling a rocky outcropping

The bones that resemble a rock [os temporale, pars petrosa] or rocky outcropping in hardness and appearance were called liqoeidh= by the ancients 11 (visible at the base of the skull in figure 5, chapter 6). The lower part of the head is like this where the dorsal medulla [medulla spinalis] descends from the skull and where the mammillary [pars petrosa, processus mastoideus] and styloid processes [facies inferior partis petrosae, processus styloideus] of the temporal bones begin. The bones of this region are the hardest and most solid of the entire body, 12 and for the sake of convenient origins and insertions of muscles is in truth as like as can be to a rough and jutting rock. Therefore I think this a well-named part, and I believe no bone in the body bounded by its own circumference was called “rocklike” or “stony” by the ancients. 13 I am aware, however, that many have applied this name only to the bones of the temples — not to all of them, but that part of them that puts out the processes just mentioned. So far as I am concerned, it will be acceptable so to name the temporal bones, provided it escape no one that the region we call the base of the skull is very often called the petrous bone by anatomists, and that they sometimes mention certain bones as if they had their own circumference when in fact they can be thought nothing other than the ends of two bones that meet (as I have already said), and sometimes a single part of one bone, as you shall hear happens in the bones [osssa coxae] that fit into the sides of the sacrum (see the three figures of chapter 29) and are given one of three names [ilium, ischium, pubis] according to their location.
