Book One -- The things that sustain and support the entire body, and what braces and attaches them all. [the bones and the ligaments that interconnect them] | Chapter 6 On the Eight Bones of the Head and the Sutures Connecting Them

The heads of men do not always differ from those of women.

Some falsely contend that it is peculiar to all men, others to women, but we have taken care to observe that it occurs very rarely in men and still more rarely or hardly ever in women. 53 You may infer from this that out of twenty skulls that one finds in cemeteries you will find scarcely one 54 whose forehead is seamed; and not any difference (though Aristotle 55 has said otherwise, clearly erring in his account of the sutures) is seen in this respect between men and women. In quadrupeds, the sagittal suture extends from the lambdoid at the back of the head to the middle of the brows [glabella] (canine skull in Chapter 9, figure 1), as the skulls of dogs, horses, cattle, and such animals 56 clearly attest. Aristotle is not to be believed when he ascribes to dogs a continuous skull unmarked by sutures; 57 the skulls of dogs clearly show the sutures we have already mentioned and nearly all that will be enumerated in this entire chapter. Some also claim that in infants this suture descends through the middle of the occipital bone and continues to the foramen [foramen magnum] of the dorsal medulla (e in figure 6), dividing the entire occipital bone.

We have certainly observed the same ourselves, but this division has more to do with a su/mfusij joint 58 than with a type of suture, since in children it is closed by cartilage and in older people no trace of this division occurs. Therefore no account of such a division appears in this text on the sutures, but will be explained in the description of the occipital bone.
