Epistola prudenti viro


Epistola prudenti viro is an apocryphal letter from a Muslim philosopher to a Christian philosopher warning of an imminent Mongol invasion of Europe. It was written in Latin in the early 1240s, when the Mongol threat was current. It is known from four manuscripts now in Munich, Vienna, Paris and Marburg.

Title

Epistola prudenti viro, the name by which the letter is now known, is based on the letter's incipit, Prudenti viro. It was coined by Charles Burnett for his critical edition of the letter.
There is no title in the Munich and Vienna manuscripts. In the Marburg manuscript, the scribe added the rubric Epistola missa Theodori philosopho imperatoris Friderici. A marginal note corrects this to Epistola missa Theodoro philosopho imperatoris Friderici. In the Paris manuscript, the rubric reads Incipit epistola Alkindi achalif, de baldac philosophi. The Paris manuscript also includes an explicit: Explicit epistola alkindi achalif de baldach philosophi. Fedor Veselov calls it the Letter of al-Kindī.

Synopsis

The letter claims to be written by "al-Kindī, the priest and philosopher of the caliph of Baghdad" and is addressed to "Theodore, the philosopher of the most invincible emperor". These are historical figures who lived centuries apart. The Muslim philosopher Abū Yūsuf Yaʿqūb ibn Isḥāq al-Kindī lived in the 9th century. Theodore of Antioch, a Syrian Orthodox Christian, was the court philosopher and astrologer of Frederick II, Holy Roman Emperor. He was still living when the letter was written. The purpose of al-Kindī in writing is to warn Theodore and Frederick of the coming invasion of the Mongols.
Having discovered many works of prophecy during his travels, al-Kindī writes to summarize them for Theodore. He describes how Alexander the Great enclosed Gog and Magog and the 22 nations of the Tartars behind the Caspian Gates. These nations are Ishmaelites and, according to prophecy, "will possess the sanctuary of God" in the last days. Al-Kindī names and describes each nation and its king, occasionally adding information about the strange fauna in its kingdom. The prophesied escape of the enclosed nations is now at hand. A fox has burrowed through the mountains and shown the nations the way out. God is allowing them to ravage the world on account of its sins. Three armies are said to be marauding at the time of writing.
The names of the kings of the 22 nations vary slightly between manuscripts. In the Marburg manuscript, they are:
  1. Anogig
  2. Agem
  3. Canenazten
  4. Depar
  5. Apodineyr
  6. Libius
  7. Limius
  8. Parizeus
  9. Decletius
  10. Zarmenus
  11. Tebleus
  12. Carmacius
  13. Calconus
  14. Amardeus
  15. Grimardius
  16. Anafagius
  17. Anafagius
  18. Alaneos
  19. Tarabus
  20. Filonicius
  21. Artineus
  22. Saltarius

Date and authorship

The letter may be said to date to around 1250. It seems, however, to have been in circulation by 1246. In the Munich manuscript, it is found in a collection of letters from the period 1241–1255. Since the collection is chronological and the undated Prudenti viro comes before the letter of 1246, it is probable that this is when it was copied into the manuscript. Laura Minervini favours a date of 1238–1240.
The letter can be connected to the court of Frederick II. It bears certain similarities to Frederick II's encyclical concerning the Mongols addressed to his fellow monarchs in 1241. In its manuscript tradition and through the text it was transmitted alongside, the letter is associated with courts of Popes Gregory IX and Innocent IV and with the courts of Frederick and his son, King Manfred of Sicily. It has been suggested that Theodore himself wrote the letter.

Purpose

It is unclear if Prudenti viro was "a mere academic exercise inspired by the contemporary atmosphere" or if it was "circulated and passed off as a genuine letter, and with a political purpose?" Calling the author a "forger", the text's first editor took the latter position. He argued that it was a piece of propaganda created in the service of Frederick II, both to stir up support for his planned crusade against the Mongols and to rebut the claims of his enemies that he was in league with them. Very tentatively, Burnett suggests that by blaming a fox for letting the nations out, the letter may be subtly throwing that accusation back at Frederick enemies, the Guelphs. Minervini agrees that the work is crusade propaganda.
On the other hand, Gabriele Bonomelli, in a dissertation on the political use of fictions, argues that the letter is an academic exercise in letter writing or ars dictaminis. The letter is essentially an unoriginal account of the enclosure of Gog, Magog and the nations and their prophesied release with the name of the Mongols taken from contemporary events and applied to the nations.

Influence

The detail of how a conniving fox helped the enclosed nations to escape is unique to Prudenti viro and the Mirabilia mundi. Through one of these, it found its way into Mandeville's Travels.
Albert of Behaim, the owner of the Munich manuscript, was a staunch opponent of Frederick II. He was probably drawn to the letter for its corroboration of the emperor's interest in astrology, for which he is criticized in a set of poems celebrating the battle of Parma in 1248 and also copied into the manuscript.

Manuscripts

Prudenti viro is preserved in four manuscripts. Each of these also contains a copy of the Pseudo-Aristotelian Secretum secretorum in the Latin translation of Philip of Tripoli.
Karl Sudhoff brought the letter to scholarly attention in 1915. The first edition was published in 1984.
