(June 2016) Pope Sylvester II Silvester II.JPG Papacy began 2 April 999 Papacy ended 12 May 1003 Predecessor Gregory V Successor John XVII Personal details Birth name Gerbertus (Gerbert) Born c. 946 Belliac, Auvergne, Kingdom of France Died 12 May 1003 Rome, Papal States, Holy Roman Empire Other popes named Sylvester Pope Sylvester II or Silvester II (c. 946 – 12 May 1003) was Pope from 2 April 999 to his death in 1003. Originally known as Gerbert of Aurillac (Latin: Gerbertus Aureliacensis or de Aurillac; French: Gerbert d'Aurillac),[n 1] he was a prolific scholar and teacher. He endorsed and promoted study of Arab and Greco-Roman arithmetic, mathematics, and astronomy, reintroducing to Europe the abacus and armillary sphere, which had been lost to Latin (though not Byzantine) Europe since the end of the Greco-Roman era.[2][3][4][5] He is said to be the first to introduce in Europe the decimal numeral system using Arabic numerals. He was the first French Pope.

In 967, Borrell II of Barcelona (947–992) visited the monastery, and the abbot asked the Count to take Gerbert with him so that the lad could study mathematics in Catalonia and acquire there some knowledge of Arabic learning. In the following years, Gerbert studied under the direction of Atto, Bishop of Vic, some 60 km north of Barcelona, and probably also at the nearby Monastery of Santa Maria de Ripoll.[7] Neither place was under Islamic rule at the time.

Borrell II of Barcelona was facing major defeat from the Andalusian powers so he sent a delegation to Córdoba to request a truce. Bishop Atto was part of the delegation that met with Al-Hakam II of Cordoba, who received him with honor. Gerbert was fascinated by the stories of the Christian Bishops and judges who dressed and talked like the Arabs, well-versed in mathematics and natural sciences like the great teachers of the Islamic madrasahs. This sparked Gerbert's veneration for the Arabs and his passion for mathematics and astronomy.

In 969, Count Borrell II made a pilgrimage to Rome, taking Gerbert with him. There Gerbert met Pope John XIII (965–972) and the Emperor Otto I, nicknamed "the Great" (936–973). The Pope persuaded Otto I to employ Gerbert as a tutor for his young son, the future Emperor Otto II (973–983). Some years later, Otto I gave Gerbert leave to study at the cathedral school of Rheims where he was soon appointed a teacher by Archbishop Adalberon.

When Otto II became Holy Roman Emperor in 973 (he was co-emperor with Otto I from 967), he appointed Gerbert the abbot of the monastery of Bobbio and also appointed him as count of the district, but the abbey had been ruined by previous abbots, and Gerbert soon returned to Rheims.

After the death of Otto II in 983, Gerbert became involved in the politics of his time. In 985, with the support of his archbishop, he opposed Lothair of France's (954–986) attempt to take the Lorraine from Emperor Otto III (983–1002) by supporting Hugh Capet (987–996). Capet became King of France, ending the Carolingian line of Kings in 987.

Adalberon died on 23 January 989.[8] Gerbert was a natural candidate for his succession,[9] but Hugh Capet appointed Arnulf, an illegitimate son of Lothair instead. Arnulf was deposed in 991 for alleged treason against the King, and Gerbert was elected his successor. There was so much opposition to Gerbert's elevation to the See of Rheims, however, that Pope John XV (985–996) sent a legate to France who temporarily suspended Gerbert from his episcopal office. Gerbert sought to show that this decree was unlawful, but a further synod in 995 declared Arnulf's deposition invalid.

Gerbert now became the teacher of Otto III, and Pope Gregory V (996–999), Otto III's cousin, appointed him Archbishop of Ravenna in 998. With the Emperor's support, he was elected to succeed Gregory V as Pope in 999. Gerbert took the name of Sylvester II, alluding to Pope Sylvester I (314–335), the advisor to Emperor Constantine I (324–337). Soon after he was elected pope, Sylvester II confirmed the position of his former rival Arnulf as archbishop of Rheims. As pope, he took energetic measures against the widespread practices of simony and concubinage among the clergy, maintaining that only capable men of spotless lives should be allowed to become bishops.

In 1001, the Roman populace revolted against the Emperor, forcing Otto III and Sylvester II to flee to Ravenna. Otto III led two unsuccessful expeditions to regain control of the city and died on a third expedition in 1002. Sylvester II returned to Rome soon after the Emperor's death, although the rebellious nobility remained in power, and died a little later. Sylvester is buried in St. John Lateran.

Legend[edit]

Pope Sylvester II and the Devil in an illustration of c. 1460. The legend of Gerbert grows from the work of the English monk William of Malmesbury in De Rebus Gestis Regum Anglorum and a polemical pamphlet, Gesta Romanae Ecclesiae contra Hildebrandum, by Cardinal Beno, a partisan of Emperor Henry IV who opposed Pope Gregory VII in the Investiture Controversy.[citation needed]

According to the legend, Gerbert, while studying mathematics and astrology in the Muslim cities of Córdoba and Seville, was accused of having learned sorcery.[10] Gerbert was supposed to be in possession of a book of spells stolen from an Arab philosopher in Spain. Gerbert fled, pursued by the victim, who could trace the thief by the stars, but Gerbert was aware of the pursuit, and hid hanging from a wooden bridge, where, suspended between heaven and earth, he was invisible to the magician.[citation needed]

Gerbert was supposed to have built a brazen head. This "robotic" head would answer his questions with "yes" or "no". He was also reputed to have had a pact with a female demon called Meridiana, who had appeared after he had been rejected by his earthly love, and with whose help he managed to ascend to the papal throne (another legend tells that he won the papacy playing dice with the Devil).[11]

According to the legend, Meridiana (or the bronze head) told Gerbert that if he should ever read a mass in Jerusalem, the Devil would come for him. Gerbert then cancelled a pilgrimage to Jerusalem, but when he read mass in the church Santa Croce in Gerusalemme ("Holy Cross of Jerusalem") in Rome, he became sick soon afterwards and, dying, he asked his cardinals to cut up his body and scatter it across the city. In another version, he was even attacked by the Devil while he was reading the Mass, and the Devil mutilated him and gave his gouged-out eyes to demons to play with in the Church. Repenting, Sylvester II then cut off his hand and his tongue.

The inscription on Gerbert's tomb reads in part Iste locus Silvestris membra sepulti venturo Domino conferet ad sonitum ("This place will yield to the sound [of the last trumpet] the limbs of buried Sylvester II, at the advent of the Lord", mis-read as "will make a sound") and has given rise to the curious legend that his bones will rattle in that tomb just before the death of a Pope.[12]

The alleged story of the crown and papal legate authority given to Stephen I of Hungary by Sylvester in the year 1000 (hence the title 'Apostolic King') is noted by the 19th-century historian Lewis L. Kropf as a possible forgery of the 17th century.[13] Likewise, the 20th-century historian Zoltan J. Kosztolnyik states that "it seems more than unlikely that Rome would have acted in fulfilling Stephen's request for a crown without the support and approval of the Emperor."[14]

Legacy[edit] Gerbert of Aurillac was a humanist long before the Renaissance. He read Virgil, Cicero and Boethius; he studied Latin translations of Porphyry, but also of Aristotle. He had a very accurate classification of the different disciplines of philosophy.

In 967, he went to Catalonia to visit the Count of Barcelona, and remained three years in the monastery of Vic, in Catalonia which, like all Catalans Monasteries, contained manuscripts from the Muslim Spain and especially from Cordoba, one of the intellectual centres of Europe at that time: the library of Al-Hakam II, for example, had thousands of books (from Science to Greek philosophy). This is where he was introduced to mathematics and astronomy.[15]

Gerbert was said to be one of the most noted scientists of his time. Gerbert wrote a series of works dealing with matters of the quadrivium (arithmetic, geometry, astronomy, music), which he taught using the basis of the trivium (grammar, logic, and rhetoric). In Rheims, he constructed a hydraulic-powered organ with brass pipes that excelled all previously known instruments,[16] where the air had to be pumped manually. In a letter of 984, Gerbert asks Lupitus of Barcelona for a book on astrology and astronomy, two terms historian S. Jim Tester says Gerbert used synonymously.[17] Gerbert may have been the author of a description of the astrolabe that was edited by Hermannus Contractus some 50 years later. Besides these, as Sylvester II he wrote a dogmatic treatise, De corpore et sanguine Domini—On the Body and Blood of the Lord.

Abacus and Hindu–Arabic numerals[edit]

Reconstructed Ancient Roman Abacus. Gerbert learned of Hindu–Arabic digits and applied this knowledge to the abacus, but probably without the numeral zero.[n 2] According to the 12th-century historian William of Malmesbury, Gerbert got the idea of the computing device of the abacus from a Spanish Arab.[citation needed] The abacus that Gerbert reintroduced into Europe had its length divided into 27 parts with 9 number symbols (this would exclude zero, which was represented by an empty column) and 1,000 characters in all, crafted out of animal horn by a shieldmaker of Rheims.[9][19][20] According to his pupil Richer, Gerbert could perform speedy calculations with his abacus that were extremely difficult for people in his day to think through in using only Roman numerals.[9] Due to Gerbert's reintroduction, the abacus became widely used in Europe once again during the 11th century.[20]

Armillary sphere and sighting tube[edit] Although lost to Europe since the terminus of the Greco-Roman era, Gerbert reintroduced the astronomical armillary sphere to Latin Europe via the Islamic civilization of Al-Andalus, which was at that time at the edge of civilization.[21][22] The details of Gerbert's armillary sphere are revealed in letters from Gerbert to his former student and monk Remi of Trèves and to his colleague Constantine, the abbot of Micy, as well as the accounts of his former student and French nobleman Richer, who served as a monk in Rheims.[23] Richer stated that Gerbert discovered that stars coursed in an oblique direction across the night sky.[24] Richer described Gerbert's use of the armillary sphere as a visual aid for teaching mathematics and astronomy in the classroom, as well as how Gerbert organized the rings and markings on his device:

An armillary sphere in a painting by Sandro Botticelli, c. 1480. First [Gerbert] demonstrated the form of the world by a plain wooden sphere... thus expressing a very big thing by a little model. Slanting this sphere by its two poles on the horizon, he showed the northern constellations toward the upper pole and the southern toward the lower pole. He kept this position straight using a circle that the Greeks called horizon, the Latins limitans, because it divides visible stars from those that are not visible. On this horizon line, placed so as to demonstrate practically and plausibly... the rising and setting of the stars, he traced natural outlines to give a greater appearance of reality to the constellations... He divided a sphere in half, letting the tube represent the diameter, the one end representing the north pole, the other the south pole. Then he divided the semicircle from one pole to the other into thirty parts. Six lines drawn from the pole he drew a heavy ring to represent the arctic polar circle. Five divisions below this he placed another line to represent the tropic of Cancer. Four parts lower he drew a line for the equinoctial circle [the equator]. The remaining distance to the south pole is divided by the same dimensions.[24]

Given this account, historian Oscar G. Darlington asserts that Gerbert's division by 60 degrees instead of 360 allowed the lateral lines of his sphere to equal to six degrees.[25] By this account, the polar circle on Gerbert's sphere was located at 54 degrees, several degrees off from the actual 66° 33'.[25] His positioning of the Tropic of Cancer at 24 degree was nearly exact, while his positioning of the equator was correct by definition.[25] Richer also revealed how Gerbert made the planets more easily observable in his armillary sphere:

He succeeded equally in showing the paths of the planets when they come near or withdraw from the earth. He fashioned first an armillary sphere. He joined the two circles called by the Greeks coluri and by the Latins incidentes because they fell upon each other, and at their extremities he placed the poles. He drew with great art and accuracy, across the colures, five other circles called parallels, which, from one pole to the other, divided the half of the sphere into thirty parts. He put six of these thirty parts of the half-sphere between the pole and the first circle; five between the first and the second; from the second to the third, four; from the third to the fourth, four again; five from the fourth to the fifth; and from the fifth to the pole, six. On these five circles he placed obliquely the circles that the Greeks call loxos or zoe, the Latins obliques or vitalis (the zodiac) because it contained the figures of the animals ascribed to the planets. On the inside of this oblique circle he figured with an extraordinary art the orbits traversed by the planets, whose paths and heights he demonstrated perfectly to his pupils, as well as their respective distances.[26]

Richer wrote about another of Gerbert's last armillary spheres, which had sighting tubes fixed on the axis of the hollow sphere that could observe the constellations, the forms of which he hung on iron and copper wires.[27] This armillary sphere was also described by Gerbert in a letter to his colleague Constantine.[28] Gerbert instructed Constantine that, if doubtful of the position of the pole star, he should fix the sighting tube of the armillary sphere into position to view the star he suspected was it, and if the star did not move out of sight, it was thus the pole star.[29] Furthermore, Gerbert instructed Constantine that the north pole could be measured with the upper and lower sighting tubes, the Arctic Circle through another tube, the Tropic of Cancer through another tube, the equator through another tube, and the Tropic of Capricorn through another tube.[29]

Works[edit]

12th century copy of De geometria. Gerbert's writings were printed in volume 139 of the Patrologia Latina. Darlington notes that Gerbert's preservation of his letters might have been an effort of his to compile them into a textbook for his pupils that would illustrate proper letter writing.[25] His books on mathematics and astronomy were not research-oriented; his texts were primarily educational guides for his students.[25]

Pope Sylvester II or Silvester II (c. 946 – 12 May 1003) was the head of the Catholic Church from 2 April 999 to his death in 1003. Born Gerbert d'Aurillac (Gerbert of Aurillac), he was a prolific scholar and teacher. He endorsed and promoted study of Arab/Greco-Roman arithmetic, mathematics, and astronomy, reintroducing to Europe the abacus and armillary sphere, which had been lost to Europe since the end of the Greco-Roman era. He is said to be the first to introduce in Europe the decimal numeral system using the Arabic numerals after his studies at the University of al-Karaouine in Morocco. He was the first French Pope.

His parentage is unknown. However, Michel Roger Lafosse, writing under the pseudonym HRH Prince Michael of Albany, claims he was a "Jewish Pope", son of Raymond III Pons of Toulouse by a first wife who

"was the daughter of the Jewish exilarch of Babylon (then visiting the Jews of Narbonnes [sic]). In AD 945, she died in childbirth, having safely delivered a son. Gerbert was born. Then Raymond married Gersende of Gascony, who gave birth to William in AD 947. Gersende saw the young Jewish boy, and one must remember that a Jew is a Jew by the fact of being his mother's son, as a threat to her own progeny. Further, Gersende was a staunch Catholic. She decided to have Gerbert educated as a Christian in the not too far distant monastery of Aurillac. The monks, however, were liberal enough to recognize the importance of Gerbert's maternal inheritance. Years later, Borrell II of Barcelona (Gerbert's maternal uncle) took it upon himself to take the personable young man, Gerbert, now nicknamed d'Aurillac, to Cordoba." (Lafosse, 53)

This passage does not explain how Gerbert's mother was a daughter of the Jewish exilarch but Gerbert's maternal uncle was Borrell II.

לימודיו בקטלוניה[%D7%A2%D7%A8%D7%99%D7%9B%D7%AA קוד מקור | עריכה] נקודת המפנה בחייו התרחשה בשנת 957, כאשר הברון בורל מברצלונה הגיע לביקור במנזר באוריאק לצורך עלייה לקברו של הקדוש סן ג'ראר. באותם ימים, הקשרים בין אקוויטן בצרפת לבין קטלוניה בספרד היו קרובים מאוד. ע"פ אחד מתלמידיו של ג'רבר, רישה דה סן רמי, ביקש המנזר מהברון בורל לקחת עמו חזרה לקטלוניה את ג'רבר, שהוכיח את עצמו כתלמיד מבריק במיוחד, כדי שירכוש שם השכלה מדעית ומתמטית[3]. קטלוניה, שגבלה באל-אנדלוס הספרדית מדרום, סימנה באותה עת את גבולה הסופי של הציוויליזציה הנוצרית- מערבית ומבצר העומד בפני פלישת המוסלמים. אולם כתוצאה מהפיגור היחסי של אירופה הנוצרית בהשוואה לעולם המוסלמי, שימשה קטלוניה נקודת ממשק של ידע ומסחר בין הציוויליזציות. ספרים וכתבי יד היו חלק מאוד מרכזי בסחר חליפין זה שהתקיים בין אל-אנדלוס לבין קטלוניה במהלך אותה תקופה, ובאמצעות קשרים אלו הצליח הרבה מהידע היווני-רומי להגיע חזרה לאירופה יחד עם תוספות של מלומדים מוסלמיים ותחומי ידע מהודו ומהמזרח הרחוק. הודות למיקום הגאוגרפי שלה, קטלוניה החזיקה באחת הספריות הגדולות באירופה במנזר סנטה מריה שבעיר ריפול, בה בילה ג'רבר שעות רבות בלמידה. תחת הדרכתו של אטו, בישוף העיר ויק, הפך ג'רבר לבקיא בצורה יוצאת דופן במקצועות המדעים, המתמטיקה והאסטרונומיה (קוואדריוויום) במהלך אותם שנים.

ג'רבר כמורה[%D7%A2%D7%A8%D7%99%D7%9B%D7%AA קוד מקור | עריכה] בשנת 970, הצטרף ג'רבר למשלחת של הבישוף אטו לרומא שם הצליח להרשים את האפיפיור יוחנן השלושה עשר בבקיאותו במדעי הקוואדריוויום. בהמלצתו הנלהבת של האפיפיור, מונה ג'רבר לאחר ביקורו להיות מורהו הפרטי של בנו שלאוטו הראשון מלך גרמניה ואיטליה (ולימים קיסר האימפריה הרומית הקדושה). לאחר שנתיים בהם שימש כמורה עבור אוטו השני, פנה ג'רבר ללימודים בבית הספר הקתדרלי בעיר ריימס, שם מונה על ידי הארכיבישוף אדלברון ללמד את מקצועות הקוודיריוויום בהם הצטיין [4]. זמן מה לאחר מכן, בשנת 983, מונה ג'רבר על ידי מעסיקו הקודם אוטו הראשון לשמש כאב המנזר בבוביו. אולם על אף ניסיונותיו הרבים לקדם רפורמות בהנהלת המנזר ובתוכניות הלימוד, נתקל ג'רבר בהתנגדות עזה ולכן שב ללימודיו בריימס כעבור שנה, שם הפך מונה לשמש כמנהל בית הספר עד שנת 997[5]. תחת ניהולם של ג'רבר מאוריאק ושל הארכיבישוף אדלברון ידע בית הספר הקתדרלי בריימס תקופה של פריחה אינטלקטואלית. הארכיבישוף אדלברון, שהיה אחיו העשיר של דוכס לוריין, נודע אף הוא במהפכנותו, ובמשך שנים היה חלוץ בניסיונות לקדם רפורמות ולימודים מדעיים[6]. באותן שנים בית הספר בריימס נודע בהתמחותו באתיקה, ברטוריקה קיקרויאנית, בספרות קלאסית ובקוואדריוויום. בשנת 989, לאחר מספר שנות הוראה בריימס, נפטר הארכיבישוף אלדברון. על אף שג'רבר נדמה כמחליפו הטבעי, מונה במקומו ארנולף, בנו הלא חוקי של לותייר מלך פרנקיה המערבית, לארכיבישוף בריימס. לאחר מינויו של ארנולף ידע בית הספר בריימס תקופה קשה, ועמד במרכזם של סכסוכים פוליטיים רבים שאילצו את ג'רבר להימלט[7].

המינוי לאפיפיורות[%D7%A2%D7%A8%D7%99%D7%9B%D7%AA קוד מקור | עריכה] מעבר להשתייכותו לבית הספר בריימס, שמר ג'רבר על קשרים קרובים גם עם גורמים בחצר הקיסרות, שם שימש בעבר כמורה. לאחר שעזב ג'רבר את ריימס מצא מקלט במגדבורג ורבנה בחצרו של אוטו השלישי, קיסר האימפריה הרומית הקדושה. בחצרו של אוטו השלישי שימש ג'רבר כמלמד וכיועצו של הקיסר, שהיה באותה עת בן שש עשרה בלבד. כקיסר האימפריה, החזיק אוטו השלישי בהשפעה רבה בנוגע למינוי של משרת האפיפיור. אין הדבר מפתיע, אם כן, שאוטו השלישי בחר בג'רבר, המורה הפרטי של משפחתו, לשמש כאפיפיור תחת גרגוריוס החמישי. וכך, בשנת 999, מונה ג'רבר מאוריאק לאפיפיור וקיבל את השם סילבסטר השני. הבחירה בשם סילבסטר לא הייתה מקרית, שכן סילבסטר הראשון היה האפיפיור בזמן הקיסר קונסטנטינוס. לאוטו השלישי, כבנה של נסיכה ביזנטית ושל קיסר האימפריה הרומית הקדושה, היו שאיפות פוליטיות גבוהות וראה בעצמו כממשיכו של הקיסר קונסטנטין. הוא אף קיווה שהאפיפיור החדש, בדמותו המהפכנית של ג'רבר מאוריאק, ישתף עמו פעולה בשאיפותיו החילוניות עבור האימפריה. לאחר מינוי כאפיפיור החל סילבסטר השני בניקוי אורוות מוסרי בשורות הכמורה והכנסייה, ויצא חוצץ כנגד תופעות של מכירת משרות ופילגשות. דעותיו ופעולותיו המהפכניות עוררו שוב התנגדות עזה, כפי שהיה בתפקידו כאב מנזר בבוביו, ואף היה עליו אף להימלט מרומא לזמן מחשש למרד בקיסר. לאחר שנים ספורות, במאי 1003, חלה סילבסטר השני במהלך טקס המיסה בכנסייה ברומא ונפטר ממחלתו כעבור תשעה ימים [8].

מורשתו האינטלקטואלית[%D7%A2%D7%A8%D7%99%D7%9B%D7%AA קוד מקור | עריכה] אחד ממקורות המידע העשירים ביותר אודות מפעלו האינטלקטואלי של ג'רבר מאוריאק הוא רישה מסן רמי, שהיה אחד מתלמידיו בבית הספר בריימס. רישה מתאר בכתביו את ג'רבר מאוריאק כמורה כריזמטי ויצירתי שהצליח, על ידי שיטות לימוד מגוונות ויישומיות, להעמיד תלמידים משכילים ובעלי ידע נדיר ביחס לאותה תקופה [9]. במשך תקופת ההוראה של ג'רבר בבית הספר בריימס הושם דגש מיוחד על לימודי הרטוריקה. כתביו של המדינאי הרומי המפורסם קיקרו, שהיו מהמקורות האהובים על ג'רבר, היוו את הבסיס ללימודים אלו. בנוסף לקיקרו נלמדו גם כתבים קלאסיים אחרים מתקופת יוון ורומא, דבר שלא היה נפוץ בתקופה זו. אולם מלבד הדגש על מדעי הטריוויום ההומניסטים, ג'רבר מאוריאק נודע במידה רבה בזכות הידע המופלג שלו במדעי הקוואדריוויום, ובכללם מתמטיקה, גאומטריה ואסטרונומיה. לימודי המתמטיקה היוו נקודת התחלה עבור התלמידים בריימס לכל לימודי המדעים המדויקים. חידוש נוסף המיוחס לג'רבר הוא הכנסתם לשימוש של הספרות הערביות בעת שבאותה תקופה היה נהוג השימוש בספרות רומיות באירופה הנוצרית[10]. בנוסף, מספר לנו רישה בכתביו על החזרתו לשימוש של מכשיר האבקוס על ידי ג'רבר ששימש עבור חישובים מהירים. לימודי האסטרונומיה היו חלק מרכזי בהוראתו של ג'רבר מאוריאק ובמסגרתם עשה שימוש נרחב באמצעי המחשה ומדידה שבנה בכוחות עצמו. הוא ביסס את הוראת האסטרונומיה והגאומטריה במידה רבה על תאוריות יווניות ופיתגוראיות, ונעזר לשם כך בספירות ובגלובוסים בכיתת הלימוד כדי להמחיש את מבנה העולם ותנועת הכוכבים[11]. ג'רבר מאוריאק לימד את כמה מהמוחות החשובים והמשפיעים ביותר של התקופה בה חי. בשל כך הפך ג'רבר למקור השראה של לימוד וידע במשך דורות רבים אחריו. ידועים לנו על לפחות שלושה עשר תלמידים שלמדו תחת ג'רבר מאוריאק בבית הספר בריימס והפכו ברבות הימים לבישופים או ארכיבישופים. תלמידים אלו לקחו עימם את הידע שרכשו מפיו של ג'רבר והעבירו אותו לתלמידיהם במנזרים ובבתי הספר הקתדרלים ברחבי אירופה[12].
