Again, While men conceive they never lie down, and enjoy not the position of rest, ordained unto all pedestrious Animals, hereby they imagine (what reason cannot conceive) that an Animal of the vastest dimension and longest duration, should live in a continual motion, without that alternity and vicissitude of rest whereby all others continue; and yet must thus much come to pass, if we opinion they lye not down and enjoy no decumbence at all. [SN: _Extensive or Tonical Motion, what?_] For station is properly no rest, but one kind of motion, relating unto that which Physitians (from _Galen_) do name extensive or tonical; that is, an extension of the muscles and organs of motion maintaining the body at length or in its proper figure. Wherein although it seem to be unmoved, it is not without all Motion; for in this position the muscles are sensibly extended, and labour to support the body; which permitted unto its proper gravity, would suddenly subside and fall unto the earth; as it happeneth in sleep, diseases, and death. From which occult action and invisible motion of the muscles in station (as _Galen_ declareth) proceed more offensive lassitudes then from ambulation. And therefore the Tyranny of some have tormented men with long and enforced station, and though _Ixion_ and _Sisiphus_ which always moved, do seem to have the hardest measure; yet was not _Titius_ favoured, that lay extended upon _Caucasus_; and _Tantalus_ suffered somewhat more then thirst, that stood perpetually in Hell. Thus _Mercurialis_ in his Gymnasticks justly makes standing one kind of exercise; and _Galen_ when we lie down, commends unto us middle figures, that is, not to lye directly, or at length, but somewhat inflected, that the muscles may be at rest; for such as he termeth _Hypobolemaioi_ or figures, of excess, either shrinking up or stretching out, are wearisome positions, and such as perturb the quiet of those parts. Now various parts do variously discover these indolent and quiet positions, some in right lines, as the wrists: some at right angles, as the cubit: others at oblique angles, as the fingers and the knees: all resting satisfied in postures of moderation, and none enduring the extremity of flexure or extension.
