As a political advisor, he advocated the foundation of English colonies in the New World to form a " British Empire", a term he is credited with coining. Dee eventually left Elizabeth's service and went on a quest for additional knowledge in the deeper realms of the occult and supernatural. He aligned himself with several individuals who may have been charlatans, travelled through Europe and was accused of spying for the English crown. Upon his return to England, he found his home and library vandalised. He eventually returned to the Queen's service, but was turned away when she was succeeded by James I. He died in poverty in London and his gravesite is unknown.

and exonerated himself, but was turned over to the Catholic bishop Edmund Bonner for religious examination. His strong, lifelong penchant for secrecy may have worsened matters. The episode was the most dramatic in a series of attacks and slanders that dogged Dee throughout his life. Clearing his name yet again, he soon became a close associate of Bonner. Dee presented Queen Mary in 1556 with a visionary plan for preserving old books, manuscripts and records and founding a national library, but it was not taken up. Instead, he expanded his personal library in Mortlake, acquiring books and manuscripts in England and on the Continent. Dee's library, a centre of learning outside the universities, became the greatest in England and attracted many scholars. When Elizabeth succeeded to the throne in 1558, Dee became her astrological and scientific advisor. He chose her coronation date and even became a Protestant. From the 1550s to the 1570s, he served as an advisor to England's voyages of discovery, providing technical aid in navigation and political support to create a " British Empire", a term he was the first to use. Dee wrote in October 1574 to William Cecil, 1st Baron Burghley seeking patronage. He claimed to have occult knowledge of treasure in the

Intended for an audience outside the universities, it proved to be Dee's most widely influential and frequently reprinted work. In 1577, Dee published , a work setting out his vision of a maritime empire and asserting English territorial claims on the New World. Dee was acquainted with Humphrey Gilbert and close to Sir Philip Sidney and his circle.


Later life

By the early 1580s, Dee was discontented with his progress in learning the secrets of nature and his diminishing influence and recognition in court circles. Failure of his ideas concerning a proposed calendar revision, colonial establishment and ambivalent results for voyages of exploration in

" or crystal-gazer, which he thought would act as an intermediary between himself and the angels. Dee's first attempts with several scryers were unsatisfactory, but in 1582 he met Edward Kelley (then calling himself Edward Talbot) who impressed him greatly with his abilities. Dee took Kelley into his service and began to devote all his energies to his supernatural pursuits. These "spiritual conferences" or "actions" were conducted with intense Christian piety, always after periods of purification, prayer and fasting. Dee was convinced of the benefits they could bring to mankind. The character of Kelley is harder to assess: some conclude that he acted with cynicism, but delusion or self-deception cannot be ruled out. Kelley's "output" is remarkable for its volume, intricacy and vividness. Dee records in his journals that angels dictated several books to him this way, through Kelley, some in a special angelic or Enochian language. In 1583, Dee met the impoverished yet popular Polish nobleman

, who, after overstaying his welcome at court, invited Dee to accompany him back to Poland. With some prompting by the "angels" (again through Kelley) and by dint of his worsening status at court, Dee decided to do so. He, Kelley and their families left in September 1583, but Łaski proved to be bankrupt and out of favour in his own country. Dee and Kelley began a nomadic life in Central Europe, meanwhile continuing their spiritual conferences, which Dee detailed in his diaries and almanacs. They had audiences with Emperor Rudolf II in Prague Castle and King Stephen Báthory of Poland, whom they attempted to convince of the importance of angelic communication. The Bathory meeting took place at the Niepołomice Castle (near Kraków, then capital of Poland) and was later analysed by Polish historians (Ryszard Zieliński, Roman Żelewski, Roman Bugaj) and writers (Waldemar Łysiak). While Dee was generally seen as a man of deep knowledge, he was mistrusted for his connection with the English monarch, Elizabeth I, for whom some thought (and still do) that Dee was a spy. The Polish king, a devout Catholic and cautious of supernatural mediators, began their meeting(s) by affirming that prophetic revelations must match the teachings of Christ, the mission of the Holy Catholic Church, and the approval of the Pope. In 1587, at a spiritual conference in

, Kelley told Dee that the angel Uriel had ordered the men to share all their possessions, including their wives. By this time, Kelley had gained some renown as an alchemist and was more sought-after than Dee in this regard: it was a line of work that had prospects for serious and long-term financial gain, especially among the royal families of central Europe. Dee, however, was more interested in communicating with angels, who he believed would help him solve the mysteries of the heavens through mathematics, optics, astrology, science and navigation. Perhaps Kelley in fact wished to end Dee's dependence on him as a diviner at their increasingly lengthy, frequent spiritual conferences. The order for wife-sharing caused Dee anguish, but he apparently did not doubt it was genuine and they apparently shared wives. However, Dee broke off the conferences immediately afterwards. He returned to England in 1589, while Kelley went on to be the alchemist to Emperor Rudolf II. Nine months later, on 28 February 1588, a son was born to Dee's wife, whom Dee baptised Theodorus Trebonianus Dee and raised as his own.


Final years

Dee returned to Mortlake after six years abroad to find his home vandalised, his library ruined and many of his prized books and instruments stolen. Furthermore, he found that increasing criticism of

practices had made England still less hospitable to his magical practices and natural philosophy. He sought support from Elizabeth, who hoped he could persuade Kelley to return and ease England's economic burdens through alchemy. She finally appointed Dee Warden of

, in 1595. This former College of Priests had been re-established as a Protestant institution by Royal Charter in 1578. However, he could not exert much control over its fellows, who despised or cheated him. Early in his tenure, he was consulted on the demonic possession of seven children, but took little interest in the case, although he allowed those involved to consult his still extensive library. Dee left Manchester in 1605 to return to London, but remained Warden until his death. By that time, Elizabeth was dead and James I gave him no support. Dee spent his final years in poverty at Mortlake, forced to sell off various possessions to support himself and his daughter, Katherine, who cared for him until his death in Mortlake late in 1608 or early in 1609 aged 81. Both the parish registers and Dee's gravestone are missing. In 2013 a memorial plaque to Dee was placed on the south wall of the present church.


Personal life

Dee was married three times and had eight children. He married his first wife, Katherine Constable in 1565. They had no children, and she died in 1574. He married his second wife, whose name is unknown, in 1575. She died in 1576, again with no children. In 1578, when he was 51, he married the 23-year-old Jane Fromond (1555–1604), who had her own connection with the Elizabethan court as a lady-in-waiting to Elizabeth FitzGerald, Countess of Lincoln until she married Dee. They had 7 or 8 children, namely: Arthur Dee (1579–1651), Michael Dee (died 1594), Rowland Dee, Katherine Dee, Madinia Dee, Frances Dee, Margaret Dee and, possibly, Theodore Dee (1588–1601). Dee referred to Thomas Jones, who is the likely loose inspiration for Welsh folkloric outlaw Twm Siôn Cati, as his cousin; the pair corresponded, and Jones visited Dee several times. From 1577 to 1601, Dee kept a sporadic diary (also referred to as his almanac), from which most of what we know of his life in that time has been gleaned. In 1587, Kelley informed Dee of the angel's wish that they share wives. Theodore Dee, born nine months later, could have been fathered by Kelley, and not Dee. Jane died in Manchester of

No records exist for his youngest daughters Madinia (sometimes Madima), Frances and Margaret after 1604, so it is widely assumed they died in the epidemic that took their mother. (Dee had by this time ceased to keep a diary.) While Arthur was a student at the Westminster School, Dee wrote to his headmaster echoing the normal worries of boarding-school parents. Arthur was an apprentice in much of his father's alchemical and scientific work and in fact often his diviner until Kelley appeared.

Achievements


Thought

Dee was an intense Christian, but his religiosity was influenced by Hermetic and Platonic- Pythagorean doctrines pervasive in the Renaissance. He believed that numbers were the basis of all things and key to knowledge. From Hermeticism he drew a belief that man had the potential for divine power that could be exercised through mathematics. His goal was to help bring forth a unified world religion through the healing of the breach of the Roman Catholic and Protestant churches and the recapture of the pure theology of the ancients.


Advocating the establishment of colonies

From 1570 Dee advocated a policy of political and economic strengthening of England and establishment of colonies in the New World. His manuscript ''Brytannicae reipublicae synopsis'' (1570) outlined the state of the Elizabethan Realm and was concerned with trade, ethics and national strength. His 1576 was the first volume in an unfinished series planned to advocate for the establishment of English colonies abroad. In a symbolic frontispiece, Dee included a figure of Britannia kneeling by the shore beseeching Elizabeth I to protect her nation by strengthening her navy. Dee used Geoffrey's inclusion of Ireland in

's conquests to argue that Arthur had established a "British empire" abroad. He argued that the establishment of new colonies would benefit England economically, with said colonies being protected by a strong navy. Dee has been credited with coining the term '' British Empire'', but Humphrey Llwyd has also been credited with the first use in his ''Commentarioli Britannicae Descriptionis Fragmentum'', published eight years earlier in 1568. Dee posited a formal claim to North America on the back of a map drawn in 1577–1580; he noted that "circa 1494 Mr. Robert Thorn his father, and Mr. Eliot of Bristow, discovered Newfound Land." In his ''Title Royal'' of 1580, he invented a claim that
Madog ab Owain Gwynedd Madoc ab Owain Gwynedd (also spelled Madog) was, according to folklore, a Welsh prince who sailed to America The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country prim ...

and King Arthur, as well as Madog, had conquered lands in the Americas, so that their heir, Elizabeth I of England, had a prior claim there.


Reputation and significance

Some ten years after Dee's death, the antiquarian Robert Cotton bought land round Dee's house and began digging for papers and artifacts. He found several manuscripts, mainly records of Dee's angelic communications. Cotton's son gave these to the scholar Méric Casaubon, who published them in 1659, with a long introduction critical of their author, as ''A True & Faithful Relation of What passed for many Yeers between Dr. John Dee (A Mathematician of Great Fame in Q. Eliz. and King James their Reignes) and some spirits''. As the first public revelation of Dee's spiritual conferences, the book was popular. Casaubon, who believed in the reality of spirits, argued in his introduction that Dee was acting as the unwitting tool of evil spirits when he believed he was communicating with angels. This book is mainly responsible for the image, prevalent for the next two-and-a-half centuries, of Dee as a dupe and deluded fanatic. About the time the ''True and Faithful Relation'' was published, members of the Rosicrucian movement claimed Dee as one of their number. There is doubt, however, that an organized Rosicrucian movement existed in Dee's lifetime, and no evidence he ever belonged to any secret fraternity. His reputation as a magician and the vivid story of his association with Edward Kelley have made him a seemingly irresistible figure to fabulists, writers of horror stories and latter-day magicians. The accretion of fanciful information about Dee often obscures the facts of his life, remarkable as they were. It also does nothing to promote his Christian leanings: Dee looked to the angels to tell him how he might heal the deep and serious rifts between the Roman Catholic Church, the Reformed Church of England and the Protestant movement in England. Queen Elizabeth I used him several times as her court astronomer, not solely because he practised Hermetic arts, but as a deeply religious and learned, trustworthy man. A revaluation of Dee's character and significance came in the 20th century, largely through the work of the historians Charlotte Fell Smith and Dame Frances Yates. Both brought into focus the parallel roles of magic, science and religion in the Elizabethan Renaissance. Fell Smith writes: "There is perhaps no learned author in history who has been so persistently misjudged, nay, even slandered, by his posterity, and not a voice in all the three centuries uplifted even to claim for him a fair hearing. Surely it is time that the cause of all this universal condemnation should be examined in the light of reason and science; and perhaps it will be found to exist mainly in the fact that he was too far advanced in speculative thought for his own age to understand." Through this and subsequent re-evaluation, Dee is now viewed as a serious scholar and book collector, a devoted Christian (albeit at a confusing time for that faith), an able scientist and one of the most learned men of his day. His Mortlake library was the largest in the country before it was vandalised, and created at enormous, sometimes ruinous personal expense; it was seen as one of the finest in Europe, perhaps second only to that of

and owned an important collection of maps, globes and astronomical instruments. He developed new instruments and special navigational techniques for use in polar regions. Dee served as an advisor to English voyages of discovery, and personally selected pilots and trained them in navigation. He believed that mathematics (which he understood mystically) was central to human learning. The centrality of mathematics to Dee's vision makes him to that extent more modern than Francis Bacon, though some scholars believe Bacon purposely downplayed mathematics in the anti-occult atmosphere of the reign of James I. Although Dee's understanding of the role of mathematics differs much from ours, its promotion outside the universities was an enduring achievement. For most of his writings, Dee chose English, rather than Latin, to make them accessible to the public. His "Mathematical Preface" to Euclid was meant to promote the study and application of mathematics by those without a university education, and was popular and influential among the "mechanicians": a growing class of technical craftsmen and artisans. Dee's preface includes demonstrations of mathematical principles that readers could perform themselves without special education or training.

Calendar

Dee was a friend of Tycho Brahe and familiar with the work (translated into English by his ward and assistant, Thomas Digges) of Nicolaus Copernicus. Many of his astronomical calculations were based on Copernican assumptions, although he never openly espoused the

reform. In 1583, he was asked to advise the Queen on the new Gregorian calendar promulgated by Pope Gregory XIII from October 1582. He advised that England accept it, albeit with seven specific amendments. The first was that the adjustment should not be the ten days that would restore the calendar to the time of the Council of Nicaea in 325 AD, but by eleven, which would restore it to the birth of Christ. Another proposal of Dee's was to align the civil and liturgical years and have them both start on 1 January. Perhaps predictably, England chose to spurn suggestions that had papist origins, despite any merit they may have had.


Voynich manuscript

Dee has often been associated with the Voynich manuscript. Wilfrid Michael Voynich, who bought the manuscript in 1912, suggested that Dee may have owned it and sold it to Rudolph II. Dee's contacts with Rudolph were less extensive than had been thought, however, and Dee's diaries show no evidence of a sale. However, he was known to have owned a copy of the ''
