Of head aking. cap. 12.
OUr Lord set a token in Cain, that was quaking of head. As Strabus saith in Glo•a.* Enerye man (sayth Strabus) that findeth mée by quaking of head and moouing of woode heart, shall knowe that I am guiltye to dye. Constantine calleth head quaking Iac∣titatio. And head quaking commeth of default and feeblenesse of vertue Regi∣tiue, in the sinewes of the necke bones, and in the brawnes of the members. In this euill bée two contrarye moouings, one vpwarde and another downeward, kinde worketh the ouer, and the disease the neather. The euil laboureth to beare downe the member lower. And kinde that hath not forsaken the gouernance of the mēber laboureth to rule it & set to it in his owne steed: and so kind laboureth to reare vp the member. And therefore quaking cōmeth of such contrary moo∣uing. The cause of the beginning is de∣fault of vertue ye moueth the brawnes, as saith Constantine: and somtime this vertue faileth because of euill complec∣tion: and for accidentes of the soule, as for dread, for gathering of spirits to the heart. Therefore the members drawe downeward by their weight and hea∣uinesse. And so for kinde hath not suffi∣saunt spirites comming togrihees, to rule the members, it may act at the full holde the members steadfastly in theyr owne place: and therfore followeth qua∣king anone. And such quaking is a manner disposition to Palsie, and name∣ly if sléeping follows with quaking: the cause whereof is coldnesse, running and hardening the substaunce of the si∣newes, that the vertue of feeling maye not thir•• it and passe therby. And euery Palsie with quaking is more easie to heale,* then the palsie that is without quaking. For in the first, the member hath not lost all kinde, as it hath in the second. Such quaking with sléeping shall be cured & healed with medicines, that heate and comfort, and dissolue and consume and wast, as with Theodori∣con, Iralogodion, and such other. Also bethes bee good, and frotings, with hot and opening hearbes and fumigations, that the closing poores maye be opened, that the superfluitie of humours maye be wasted, the spirits excited, and the si∣newes comforted.
