most wise and vertuous Lord Iohn Steigerus Consull
of the noble Common wealth of Berna, his good
Lord and Patrone, Lewes Lauaterus
of Tigurine, wisheth health.

M Any and diuers things are reasoned vpon, both of the learned and vnlearned, as wel of other matter, as also of Spirites, which are seene and heard, and make men afraid in the night season, and in the day time, by sea and by lande, in the fields, woods, and houses: And likewise concerning such straunge things which for the most part happen before the death of certain men, especially great Princes, and before notable innouations of Kingdomes and Empires. Many which neuer sawe or heard any of these things, suppose all that is reported of them, to be meere trifles and old wiues tales: for so much as simple men, and such as are fearefull and superstitious, perswade themselues they haue seen this or that, when indeed the matter is farre otherwise. Againe, there are some, which assoone as they heare of any thing, especially if it happen in the night, they by and by thinke some spirite dooth walke, and are maruellously troubled in minde, because they cannot discerne naturall things from spirites. And some (chiefly those whiche hunt after gaines, by the soules of dead men) affirme that the most part of such things which are heard or seene, are the soules of dead men, which craue helpe of them that are liuing, to be deliuered out of the torments of most cruell paine in Purgatorie. Many not only of the common sort, but also men of excellent knowledge, do maruell whether there be any spirits or no, and what maner of things they are. Yea and some of my familiar friends haue many times requested me, to shew them my opinion concerning these matters. Wherfore me seemeth it shall be worth my laboure, if I declare briefly and plainly out of the word of God, what we ought to iudge concerning these things. For the Ministers of Gods Church can take nothing more profitable in hande, than to instruct the people of God purely and plainly, in such necessary matters as come in question out of the word of God, which is a lanterne (as the Psalmist saith) vnto our feete, and a light vnto our pathes: and to deliuer them from all errour and superstition, and bring them out of all wauering and doubt. And verily their studie & diligence is to be highly commended, who for these fewe yeares ago, haue set forth certaine bookes drawne out of the scriptures, written in the Germaine tongue against sundrie errours: and theirs likewise who in these our dayes by writing of bookes do teache, instruct, and confirme the rude and vnlearned people. For amongst many other excellent benefits, which God our heauenly Father hath bestowed vppon mankinde, this also is a great and most liberall gift, that in this latter, and as it were old age of the world, he hath brought to light by the Art of Imprinting, aswel many other good Authours, as also the holie scriptures of the old and new Testament, written in diuers languages: whereby he doth not onlie teach vs amply and fully what to beleeue, and what to doo, but also mightily subuerteth and quite ouerthroweth diuers and sundrie errours, which by little and little haue crept into the Church. Truly all such are verie vngrateful towards God, which do not willingly acknowledge this so notable a benefit.

As touching this my treatise concerning Spirits, and straunge wonders, I haue deuided it into three partes for the more cleare vnderstanding therof. In the first parte I shewe, that there are visions and spirits, and that they appeare vnto men sometimes, and that many & maruellous things happen besides the ordinarie course of nature. In the second I discusse what maner of things they are, that, is not the soules of dead men, as some men haue thought, but either good or euill angels, or else some secret and hid operations of God. In the third I declare why God doth somtime suffer Spirits to appear, and diuers forewarnings to happen: and also how me ought to behaue themselues when they happen to meete with such things. In these points or partes, the chiefest thing wheron men vse to reason touching this matter, are conteined. Now I mean to handle this matter, being very obscure and intricate, with many questions, (I trust) so plainly, & clerely out of the holy scriptures, whereon we may surely stay our selues, out of the anciet fathers, allowed historiographers, and other good writers, that those which are studious and louers of Gods truth, may well vnderstand what may be denied & thought of those apparitions, & other straunge & maruellous matters. And I also trust that euen our aduersaries also, (in case they wil lay their affections aside, but a litle while) wil say that I haue truly alleaged all their arguments, and confuted the without any railing or bitternesse. For my purposed ende is according to the doctrine of Saint Paule, to edifie and not to destroy.

As touching diuinations, blessings, iuglings, coniurings, and diuers kinds of sorcerie, and generally of all other diuellish practises, certaine learned men of our time haue written bookes, as Gasper Pencerus, Ioannes Viera, Ludouicus Mellichius, and perchaunce some others also, whose worke I haue not yet seene. It is not long ago since Ioannes Riuius a man learned and eloquent, published a booke in the latin toong, entreating of spirites and superstition. In the which booke albeit very briefly, yet doth hee as he is wont in all things, very finely & eloquently intreat of this matter, and of other foolishe superstitions. And albeit that I do write more largely of this, yet was it not my minde to gather togither al those thinges which I could haue spoken and alleaged touching the same matter: but only such as seeme the chiefest and most especiall points, partly because I would not be tedious to the reader, & partly also least my books shuld grow vnto an ouer great quantity. I haue great hope that Ioachimus Camerarius, that excellent man, who readeth the auncient writers both greeks and latins, with exquisite iudgemet, and hath great experience in all things, will shortly write learnedly & at large of this matter, and also of others like vnto it. For so muche hee seemeth to promise in his preface to Plutarches Booke, De defectu oraculorum, & figura, & consecrata Delphis (wherin he handleth the nature and operatios of diuels) and also in other of his writings. I for my parte had once written this my treatise in the vulger tong, and now bicause I trust it shal be also profitable to other men, I haue translated it into latin, adding certaine things thereto.

This my booke which I haue with great labour and study gathered out of other mes writings I present & offer vnto you (most noble consul) according to the ancient fashion & custome: not for that I suppose you haue any neede of my teaching, touching these things which are herein hadled. (For I am not ignoraunt, vnder what teachers you haue atteined vnto true learning, and how you haue and do continually read ouer sundry good authors with perfect knowledge in many tongues.) But partly that I might purchase credit and authoritie vnto this my booke with those men, vnto whome your goodnes, godlinesse and constancie (which you haue alwaies hitherto euermore shewed, and yet do shewe, in setting forth true religio, & mainteining good lawes) is throughly knowne: and partly that I might shew my selfe in some respecte thankfull vnto you. For your honour hath bestowed many benefits on me, whom you onlie knowe by sight, and vppon other Ministers of the Church, wherby ye haue so bound me vnto you, that I shall neuer be able to make any recompence.

Wherefore I most earnestly beseech you, not to refuse this signe and token of my good wil, be it neuer so simple: but rather to vouchsafe, whe ye haue leisure from the laboure and toile of the common wealth, to reade ouer this my booke: for I haue good hope it will not seeme vnpleasaunt vnto you & others in the reading, as wel for the plaine order I vse therin, as also for the sundrie and manifold histories in it recited.

Almightie God, who hath so blessed you with his heauenly gifts, that for them, (albeit very yong) you haue aspired vnto the highest degree in your noble citie and dominio of Berna, vouchsafe to preserue you in health, and increase and multiply his good gifts in you. My Lords & brethren the ministers of Tigurin, and also your old companion master George Grebelius, that excellent man in lerning, vertu, and nobilitie, hartily salute your Lordship. From Tigurin in the month of Ianuary, the year of Christs Natiuitie. 1570.
