Trithemius
Johannes Trithemius (; 1 February 1462 – 13 December 1516), born Johann Heidenberg, was a German Benedictine abbot and a polymath who was active in the German Renaissance as a lexicographer, chronicler, cryptographer, and occultist. He is considered the founder of modern cryptography (a claim shared with Leon Battista Alberti) and steganography, as well as the founder of bibliography and literary studies as branches of knowledge. He had considerable influence on the development of early modern and modern occultism. His students included Heinrich Cornelius Agrippa and Paracelsus. Early life The byname ''Trithemius'' refers to his native town of Trittenheim on the Moselle River, at the time part of the Electorate of Trier. When Johannes was still an infant his father, Johann von Heidenburg, died. His stepfather, whom his mother Elisabeth married seven years later, was hostile to education and thus Johannes could only learn in secret and with many difficulties. He learned Greek, ...

Trithemius Cipher
In cryptography, the ''tabula recta'' (from Latin '' tabula rēcta'') is a square table of alphabets, each row of which is made by shifting the previous one to the left. The term was invented by the German author and monk Johannes TrithemiusSalomon, Data Privacy, page 63 in 1508, and used in his Trithemius cipher. Trithemius cipher The Trithemius cipher was published by Johannes Trithemius in his book '' Polygraphia'', which is credited with being the first published printed work on cryptology. Trithemius used the ''tabula recta'' to define a polyalphabetic cipher, which was equivalent to Leon Battista Alberti's cipher disk except that the order of the letters in the target alphabet is not mixed. The ''tabula recta'' is often referred to in discussing pre-computer ciphers, including the Vigenère cipher and Blaise de Vigenère's less well-known autokey cipher. All polyalphabetic ciphers based on the Caesar cipher can be described in terms of the ''tabula recta''. The t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paracelsus
Paracelsus (; ; 1493 – 24 September 1541), born Theophrastus von Hohenheim (full name Philippus Aureolus Theophrastus Bombastus von Hohenheim), was a Swiss physician, alchemist, lay theologian, and philosopher of the German Renaissance. He was a pioneer in several aspects of the " medical revolution" of the Renaissance, emphasizing the value of observation in combination with received wisdom. He is credited as the "father of toxicology". Paracelsus also had a substantial influence as a prophet or diviner, his "Prognostications" being studied by Rosicrucians in the 1600s. Paracelsianism is the early modern medical movement inspired by the study of his works. Biography Paracelsus was born in Egg an der Sihl, a village close to the Etzel Pass in Einsiedeln, Schwyz. He was born in a house right next to a bridge across the Sihl river (known as ''Teufelsbrücke''). The historical house, dated to the 14th century, was destroyed in 1814. The ''Restaurant Krone'' now stands in its pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steganography
Steganography ( ) is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. In computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. The word ''steganography'' comes from Greek ''steganographia'', which combines the words ''steganós'' (), meaning "covered or concealed", and ''-graphia'' () meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his '' Steganographia'', a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or to be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are f ...

Sponheim
Sponheim is a municipality in the district of Bad Kreuznach in Rhineland-Palatinate in western Germany. History Sponheim was the capital of the County of Sponheim. Sponheim Abbey There was a Benedictine abbey which was founded in 1101 by Stephan II, Count of Sponheim not far from the comital residence at Castle Sponheim. Johannes Trithemius was one of the abbots. Traveling from university to his home town in 1482, he was surprised by a snowstorm and took refuge in the Benedictine abbey of Sponheim near Bad Kreuznach. He decided to stay and was elected abbot in 1483, at the age of twenty-one. In his time, the abbey library increased from around fifty items to more than two thousand. However, his efforts were not met with praise, and his reputation as a magician did not further his acceptance. Increasing differences with the convent led to his resignation in 1506.

Heinrich Cornelius Agrippa
Heinrich Cornelius Agrippa von Nettesheim (; ; 14 September 1486 – 18 February 1535) was a German polymath, physician, legal scholar, soldier, theologian, and occult writer. Agrippa's ''Three Books of Occult Philosophy'' published in 1533 drew heavily upon Kabbalah, Hermeticism, and neo-Platonism. His book was widely influential among occultists of the early modern period, and was condemned as heretical by the inquisitor of Cologne. Life Agrippa was born in Nettersheim, near Cologne on 14 September 1486 to a family of middle nobility.Valente, Michaela "Agrippa, Heinrich Cornelius". In: ''Dictionary of Gnosis and Western Esotericism'' (Wouter J. Hanegraaff, ed.), pp. 4–8. Brill, 2006. . Many members of his family had been in the service of the House of Habsburg. Agrippa studied at the University of Cologne from 1499 to 1502, (age 13–16) when he received the degree of ''magister artium''. The University of Cologne was one of the centers of Thomism, and the faculty of art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramon Llull
Ramon Llull (; c. 1232 – c. 1315/16) was a philosopher, theologian, poet, missionary, and Christian apologist from the Kingdom of Majorca. He invented a philosophical system known as the ''Art'', conceived as a type of universal logic to prove the truth of Christian doctrine to interlocutors of all faiths and nationalities. The ''Art'' consists of a set of general principles and combinatorial operations. It is illustrated with diagrams. A prolific writer, he is also known for his literary works written in Catalan, which he composed to make his ''Art'' accessible to a wider audience. In addition to Catalan and Latin he also probably wrote in Arabic (although no texts in Arabic survive). His books were translated into Occitan, French, and Castilian during his lifetime. Although his work did not enjoy huge success during his lifetime, he has had a rich and continuing reception. In the early modern period his name became associated with alchemical works. More recently he has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order Of Saint Benedict
The Benedictines, officially the Order of Saint Benedict ( la, Ordo Sancti Benedicti, abbreviated as OSB), are a Christian monasticism, monastic Religious order (Catholic), religious order of the Catholic Church following the Rule of Saint Benedict. They are also sometimes called the Black Monks, in reference to the colour of their religious habits. They were founded by Benedict of Nursia, a 6th-century monk who laid the foundations of Benedictine monasticism through the formulation of his Rule of Saint Benedict. Despite being called an order, the Benedictines do not operate under a single hierarchy but are instead organised as a collection of autonomous monasteries. The order is represented internationally by the Benedictine Confederation, an organisation set up in 1893 to represent the order's shared interests. They do not have a superior general or motherhouse with universal jurisdiction, but elect an Abbot Primate to represent themselves to the Holy See, Vatican and to the worl ...

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leon Battista Alberti
Leon Battista Alberti (; 14 February 1404 – 25 April 1472) was an Italian Renaissance humanist author, artist, architect, poet, priest, linguist, philosopher, and cryptographer; he epitomised the nature of those identified now as polymaths. He is considered the founder of Western cryptography, a claim he shares with Johannes Trithemius. Although he often is characterized exclusively as an architect, as James Beck has observed, "to single out one of Leon Battista's 'fields' over others as somehow functionally independent and self-sufficient is of no help at all to any effort to characterize Alberti's extensive explorations in the fine arts". Although Alberti is known mostly for being an artist, he was also a mathematician of many sorts and made great advances to this field during the fifteenth century. The two most important buildings he designed are the churches of San Sebastiano (1460) and Sant'Andrea (1472), both in Mantua. Alberti's life was described in Giorgio Vasari's ' ...
