A letter, containing a most briefe discourse apologeticall with a plaine demonstration, and feruent protestation, for the lawfull, sincere, very faithfull and Christian course, of the philosophicall studies and exercises, of a certaine studious gentleman: an ancient seruant to her most excellent Maiesty royall.

To the most Reuerend father in God, the Lord Archbishop of Canturbury, Primate and Metropolitane of all England, one of her Ma∣iesties most honorable priuy Counsaile: my singular good Lord.

MOst humbly and hartily I craue your Graces pardon, if I offende any thing, to send, or present vnto your Graces hand, so simple a discourse as this is: Although, by some sage and discreet my friends their opiniō, it is thought not to be impertinent, to my most needfull suites, presently in hand, (before her most excellent Maiesty Royall, your Lordships good Grace, and other the Right honorable Lordes of her Maiesties priuy Counsaile) to make some part of my former studies, and studious exercises (within and for these 46, yeeres last past, vsed and continued) to be first knowne and discouered vnto your Grace, and o∣ther the Right honorable my good Lordes, of her Maie∣sties priuy Counsaile: And, Secondly, afterwardes, the same to be permitted to come to publique view: Not so

much, to stop the mouthes, and, at length to stay the im∣pudent attemptes, of the rash, and malicious deuisers, and contriuers of most vntrue, foolish, and wicked re∣ports, and fables, of, and concerning my foresaid studious exercises, passed ouer, with my great, (yea incredible) paines, trauels, cares, and costs, in the search, and lear∣ning of true Philosophie; As, therein, Só, to certifie, and satisfie the godly and vnpartiall Christian hearer, or reader hereof: That, by his own iudgement, (vpon his due con∣sideration, and examination of this, no little parcell, of the particulars of my foresaid studies, and exercises phi∣losophicall annexed) He will, or may, be sufficiently in∣formed, and perswaded; That I haue wonderfully labo∣red, to finde, follow, vse, & haunt the true, straight, and most narrow path, leading all true, deuout, zealous, faith∣full, and constant Christian students, ex valle hac miseriae, & miseria istius vallis: & tenebrarum Regno; & tenebris istius Regni, ad montem sanctum Syon, & ad caelestia taber∣nacula. All thankes, are most due, therefore, vnto the Al∣mighty: Seeing, it so pleased him, (euen from my youth, by his diuine fauor, grace, and helpe) to insinuate into my hart, an insatiable zeale, & desire, to knowe his truth: And in him, and by him, incessantly to seeke, and listen af∣ter the same; by the true philosophicall method and har∣mony: proceeding and ascending, (as it were) gradatim, from things visible, to consider of thinges inuisible: from thinges bodily, to conceiue of thinges spirituall: from things transitorie, & momentanie, to meditate of things permanent: by thinges mortall (visible and inuisible) to haue some perceiuerance of immortality. And to con∣clude,

most briefely; by the most meruailous frame of the whole World, philosophically viewed, and circumspectly wayed, numbred, and measured (according to the talent, & gift of God, from aboue alotted, for his diuine purpo∣ses effecting) most faithfully to loue, honor, and glorifie alwaies, the Framer, and Creator thereof. In whose work∣manship, his infinite goodnesse, vnsearchable wisdome, and Almighty power, yea, his euerlasting power, and diuinity, may (by innumerable meanes) be manifested, and demonstrated. The truth of which my zealous, care∣full, aud constant intent, and endeuour specified; may (I hope) easilie appeare by the whole, full and due suruey, and consideration of all the Bookes, Treatises, and dis∣courses, whose Titles onely, are, at this time, here annex∣ed, and expressed: As they are set down in the sixt Chap∣ter, of an other little Rhapsodicall Treatise, intitled, The Cōpendious Rehearsall, &c. writtē aboue two yeares since: for those her Maiesties two honorable Commissioners; which her most excellent Maiesty had most graciouslie sent to my poore Cottage, in Mortlake: to vnderstand the matters, and causes at full; through which, I was so ex∣treamely vrged to procure at her Maiesties handes such honorable Surueiors & witnesses to be assigned, for the due proofe of the contents, of my most humble and pitifull supplication, exhibited vnto her most excellent Maiesty, at Hampton Court, An. 1592. Nouemb. 9. Thus therefore (as follow∣eth) is y^e said 6. Chapter there, recorded.

With many other bookes, pamphlets, discourses, in∣uentions, and conclusions, in diuers Artes and matters: whose names, need not in this Abstract to be notified: The most part of all which, here specified, lie heere before your Honours vpon the table, on your left hand. But by other bookes and writinges, of an other sort, (if it so please God, and that he wil grant me life, health, and due maintenance thereto, for some ten or twelue yeares next ensuing) I may, hereafter make plaine, and without doubt, this sentence to be true, Plura latent, quàm patent.

Thus far (my good Lord) haue I set downe this Cata∣logus, out of the foresaid sixt Chapter, of the booke, whose title is this:

The Compendious rehearsall of Iohn Dee, his dutifull decla∣ration [ 49] and proofe of the course and race of his studious life, for the space of halfe an hundred yeeres, now (by Gods fauor and helpe) fully spent, &c.

To which compendious rehearsall, doth now belong an Appendix, of these two last yeeres: In which I haue had ma∣ny iust occasions, to confesse, that Homo Homini Deus, and Homo Homini Lupus, was and is an Argumēt, worthy of the decyphering, & large discussing: as may, one day, hereafter (by Gods helpe) be published, in some maner very strange. And besides all the rehearsed books, & treatises of my wri∣ting, or handling hitherto, I haue iust cause, lately giuen me to write & publish a Treatise, with Title, De Horizonte Ae∣ternitatis: [ 50] to make euident, that one Andreas Libauius, in a booke of his, printed the last yeere, hath vnduly conside∣red a phrase of my Monas Hieroglyphica: to his misliking:

by his own vnskilfulnes in such matter: and not vnderstan∣ding my apt application thereof, in one of the very princi∣pal places, of the whole book. And this booke of mine, (by Gods help and fauour) shall be dedicated vn∣to her most excellent maiesty Roi∣all: And this Treatise doth con∣taine three bookes, The first inti∣tled, [ 1] De Horizonte: liber Mathe∣maticus [ 51] & Physicus. The Secōd, De [ 2] Aeternitate: liber Theologicus, Metaphysicus & Mathematicus. The Third, De Horizonte Aeter∣nitatis: [ 3] liber Theologicus, Mathe∣maticus, & Hierotechnicus.

¶ Truly I haue great cause to praise and thanke God, for your graces verie charitable vsing of me: both in sun∣dry points else, & also in your fauorable yelding to, yea & notifying the due meanes for the performance of her Sa∣cred Maiesties most gracious and bountifull disposition, resolution, and very royall beginning, to restore and giue vnto me (her Ancient faithfull seruant) some due mainte∣nance: to leade the rest of my old daies, in some quiet and comfort: with habilitie, to retaine some speedy, faire, and Orthographicall writers, about me; and the same skilfull in Latine and Greeke (at the least:) aswell for mine owne bookes, and workes, faire and correctly to be written (such I meane, as either her most excellent Maiestie, out of the premisses will make choise of, or command to be finished or published: or such of them, as your grace shall thinke

meete or worthy for my farther labor to be bestowed on:) as else for the speedy, faire, and true writing out of other ancient Authors their good and rare workes, in greeke or Latine: which by Gods prouidence, haue been preserued frō the spoile made of my Librarie, & of all my moueable goods here: &c. Anno. 1583. ✚ In which Librarie, were about 4000 bookes: whereof, 700. were anciently written by hande: Some in Greeke, some in Latine, some in Hebrue: And some in other lan∣guages (as may by the whole Cata∣logus thereof appeare.) But the great losses and dammages which in sundry sorts I haue sustained, do not so much grieue my hart, as the rash, lewde, fond, and most vntrue fables and reports of me, and my studies philosophicall, haue done, & yet do: which cōmonly, after their first hatching, and diuelish deuising, immediatly with great speede, are gene∣rally all the Realme ouerspread; and to some, seeme true; to other, they are doubtfull: and to only the wise, modest, discreet, godly, and charitable (and chiefelie to such as haue some acquaintance with me) they appeare, and are knowne to be fables, vntruths, and vtterly false reports, and sclaunders. Well, this shall be my last charitable giuing of warning, and feruent protestation to my Countrimen and all other in this case:

Before the Almighty our God, and your Lordships good grace, this day, on the perill of my soules damnation (if I lie, or take his name in vaine herein) I take the same God, to be my

witnesse; That, with all my hart, with all my soule, with all my strength, power, and vnderstanding (according to the measure thereof, which the Almighty hath giuen me) for the most part of the time, from my youth hitherto, I haue vsed, and still vse, good, lawfull, honest, christian, and diuinely pre∣scribed meanes, to attaine to the knowledge of those truthes, which are meet, and necessary for me to know; and wherwith to do his diuine Maiesty such seruice, as hee hath, doth, and will call me vnto, during this my life: for his honor and glory aduancing, and for the benefit, and commoditie publique of this kingdome; so much, as by the will, and purpose of God, shall lie in my skill, and hability to performe: as a true, faith∣full, and most sincerely dutifull seruant, to our most grati∣ous and incomparable Queene Elizabeth, and as a very com∣fortable fellow-member of the body politique, gouerned vn∣der the scepter Royal of our earthly Supreame head (Queene Elizabeth) and as a liuely sympathicall, and true symetricall fellow-member, of that holy and mysticall body, Catholicklie extended and placed (wheresoeuer) on the earth: in the view, knowledge, direction, protection, illumination, and consola∣tion of the Almighty, most blessed, most holy, most glorious, comaiesticall, coëternall, and coëssentiall Trinity: The head of that body, being only our Redeemer, Christ Iesus, perfect God and perfect man: whose returne in glory, we faithfully awaite, and daily, do very earnestly cry vnto him, to hasten his second comming, for his electes sake: iniquity doth so on this earth, abound, and preuaile, and true faith with charity, and Euangelicall simplicity, haue but colde, slender, and vn∣certaine intertainement, among the worldly-wise men of this worlde.

Therefore (herein concluding) I beseech the Almighty God, most aboundantly to increase and confirme your graces

heauenly wisdome, and endue you with all the rest of his hea∣uenly gifts, for the relieuing, refreshing, and comforting, both bodily and spiritually, his little flocke of the faithfull, yet mili∣tant here on earth. Amen.
