Chap. VII. Touching the Forehead.
THe Hairy part of the Head being* 1.1 explained, the smooth part or FACE follows, which in man is void of Hairs, otherwise then i•• is in Beasts, for Beauties sake; it is also called Vultus because of the judg∣ment of the wil, which is Conspicuous of the Face.
The upper part thereof, viz. the Fore∣head is termed Frons a ferendo from carry∣ing,* 1.2 as some conceive, because it carries in it tokens of the mind: the rest thereof, from the Eye-brows to the Chins end, is the lower part, in which are many other parts, which are here∣after to be explained in order, external and internal, the Organs of the Senses, Muscles of the Eyes, Nose, Lips, &c.
The Skin of the Forehead, because it is moved, therefore it hath Muscles, which* 1.3 Platerus terms the signifiers of the Affecti∣ons of the Mind. Now the Muscles of the* 1.4 Forehead do lift up the Eye-brows, and are thickest at the said Eye-brows.
They arise from the Skull, near the coronal Suture, and are knit at the sides to the temporal Muscles, but in the middle they are distinguished a little above, but beneath they are so nearly associated, that they seem to be one Muscle, and end at the Eye-brows. Yet I have observed in a large nosed person, that an Appen∣dix of the said Muscles did reach to the Gristles of the Nose.
They have straight Fibres. Surgeons therefore must not cut them athwart, least they destroy the lifting up of the Eye-brows; but upwards, according to their length. Hosman after Aquapendent stands for oblique fibres, on the right side from the right hand to the left, on the left side from the left hand to the right. But this they do against Experience, ocular Inspection, and Reason. For the skin of the Forehead is by a straight course, either elevated or depressed by help of right fibres, which are the cause of straight motion. In the point of right fibres, we have the Consent of great Anatomists Vesalius, Laurentius, Bauhinus, Platerus, Ves∣lingus, &c.
And because the skin of the Forehead grows close to these Muscles, therefore both the Forehead and the Eye-brows are moved.
Howbeit there are somtimes also two Muscles in the binder part of the Head, which move the skin there∣of, short, thin and broad, with straight fibres, ending above into a broad Tendon, and touching the hinder∣more Muscles of the Ears, in their sides. Some men that are furnished with these Muscles, can draw the skin of their Heads backwards.
