Petrus PisanusCiaconius (Alfonso Chacón), in: Vitae et res gestae Pontificum romanorum et S.R.E. Cardinalium second ed. (ed. Augustinus Olduin) Tomus I (Rome: Filippo and Antonio Rossi 1677), p. 918, says that Petrus was "Petrus Gerardescus ex Comitibus Donaritici de Natalico, nobilis Pisanus". There is no evidence for the assertion. Cf. Maria Luisa Ceccarelli Lemut, "La Maremma populoniese nel Medioevo," in: Giovanna Bianchi (2003), Campiglia. Un castello e il suo territorio. I. Ricerca storica. II. Indagine archeologica, (Firenze: All’Insegna del Giglio 2003), pp. 1-110, esp. p. 14 Tavola VI. (died in 1145 or later) was a Roman Catholic Cardinal. He began his career in papal service as a scriptor in the chancellery. He was appointed Deacon of San Giorgio in Velabro, and then promoted Cardinal-priest of Santa Susanna. He served briefly as papal legate in Corsica, before becoming a permanent member of the papal court. He participated in the papal elections of 1118, 1124, and 1130. In 1130, he chose to support the Obedience of Anacletus II rather than that of Innocent II. After Anacletus died in 1138, he joined the Obedience of Innocent II, and survived the purge of 1139.

Education He was learned in canon law, the decretals and civil law.James Raine (ed.) (1886), The Historians of the Church of York and Its Archbishops. Volume II (London: Longman 1886), p. 175: "Hic vero Petrus clericus erat bonus, castus, et religiosus, canonorum et decretorum et legum scriptarum non mediocris peritus".

Petrus began his career as a Scriptor and Chaplain of Pope Paschal II by 1104.Pandulf of Pisa, "Life of Gelasius II," in: Watterich II, p. 93. On the basis of handwriting, Huls, p. 219, note 1, identifies three Petruses who were scriptores, and sorts out the documents signed by Cardinal Petrus, between 1104 and 1108. The three Petrus Scriptor were conflated by Brixius, p. 39, who then places the beginning of Petrus Pisanus' career in 1094.

Cardinal deacon He was already a cardinal-deacon by 16 October 1113, when he subscribes himself as "Petrus Pisanus sancti Adriani diaconus".Huls, p. 219, with note 2. P. Kehr, "Papsturkunden in Benevent und der Capitanata," Nachrichten von der Königl. Gesellschaft der Wissenschaften zu Göttingen phil.-hist. Klasse (Göttingen 1898), p. 71.

On 21 and 22 December 1116, Petrus, still a cardinal-deacon, was in Trastevere with Pope Paschal, probably at the papal residence at S. Maria Antiqua, where he subscribed a papal decree in favor of the canons of S. Maria in Portu Ravennatis.Hüls, p. 219, with notes 6 and 7. P. F. Kehr, Italia sacra V (Berlin: Weidmann 1911), pp. 96-97, nos. 2 and 3. Monumenta Germaniae Historica. Libelli de Lite Vol. III (Hannover: Hahn 1897), p. 478 (from Gerhohus of Reichersberg).

Cardinal priest Pope Paschal died on 21 January 1118.J.N.D. Kelly and M. J. Walsh, Oxford Dictionary of Popes second edition (Oxford 2010), p. 160. Cardinal Petrus Pisanus of Santa Susanna was present at the election of his successor, Cardinal Giovanni Gaetani, who took the name Gelasius II.Watterich II, p. 94. He was elected on the Vigil of the Conversion of St. Paul the Apostle, January 24.Gregorovius IV. 2, pp. 377-382. "Annales Romani,": in: Monumenta Germaniae Historica Scriptorum Tomus V (Hannover: Hahn 1844), p. 478. Watterich II, p. 112. Forced to flee Rome because of the violence of the Frangipani and the approach of the army of the Emperor Henry V, Gelasius took refuge in Gaeta, where he was consecrated a bishop and enthroned by three cardinal-bishops, Lamberto of Ostia, Pietro of Porto, and Vitalis of Albano.Watterich, pp. 94-95; 98. Gregorovius IV. 2, pp. 377-381. The papal court returned to Rome early in July, after the withdrawal of Henry V, but factional fighting in Rome forced them to flee again at the end of August, first to Pisa, then, Genoa, then France.Watterich, pp. 101-102. Jaffé, pp. 775-777. Gregorovius, pp. 386-389.

Papal legate On 13 September 1118, Petrus Pisanus was in Pisa, along with the exiled Pope Gelasius, where he subscribed a document.Hüls, p. 210, with note 3. Gregorovius IV. 2, pp. 389-390. In autumn 1118, Pope Gelasius sent Cardinal Petrus as his legate in Corsica. He was there at least until April 1119.P. F. Kehr, Italia Pontificia X (Turici: Weidmann 1975), p. 413 no. 594; pp. 472-473. Gelasius, in exile from Rome, died at the monastery of Cluny on 29 January 1119. Petrus Pisanus was not able to be present at the papal election that followed immediately. Archbishop Guy de Bourgogne was elected pope on 2 February 1119, and took the name Calixtus II. Petrus finally joined the new pope at Auxerre in December 1119.Hüls, p. 210, note 8. Hugh the Chanter, in: Raine (ed.) (1886), p. 175. Jaffé, p. 791. From Auxerre, he and the papal court proceeded to Valence (27 February 1120), Gap (11 March), Pisa (14 May), and Volterra (21 May).Hüls, p. 210, with notes 10-13. They reached Rome on 3 June.Jaffé, p. 795.

Elections of 1130

Honorius II died in Rome in the monastery of S. Gregory on the Clivus Scauri, near the Colosseum, on 13 February 1130, after a protracted illness.Jaffé, p. 839. Watterich II, p. 158. S. Löwenfeld, "Zur Papstgeschichte des 12. Jahrhunderts. 1. Ueber die letzten Tage Honorius II.," Neues Archiv der Gesellschaft für äältere deutsche Geschichtskunde 11 (1886), pp. 595-596. Even before the pope was dead, however, a group of cardinals in his entourage formed a plan to get the others to agree to choosing the next pope by a committee. The committee was to consist of two cardinal-bishops,Gregorovius IV, p. 420, errs in placing Cardinal Petrus of Porto on the committee. The two cardinal-bishops, according to Bishop Hubertus (Watterich II, p. 180, were Guilelmus of Praeneste and Conradus of Sabina, both creatures of Aymeric. three cardinal priests, and two cardinal-deacons. The committee was weighted in favor of the candidate of the Chancellor Cardinal Aymeric and his Frangipani supporters,Zṏpffel, pp. 209-210. Gregorio Papareschi, who was in fact a member of the committee.Watterich II, pp. 179-180; 188; from a letter of Bishop Hubertus of Lucca to Bishop Norbert of Magdeburg. Gregorovius IV, pp. 419-420. Zṏpffel, p. 272. Cardinal Petrus Pisanus, who was present at the meeting and who was offered a place on the committee,Watterich II, p. 180 places the blame for the plot squarely on the shoulders of Cardinal Aymeric.Watterich, p. 188: "Sicque non cooperto corpore, contempto ipsorum eorundem iuramento et anathemate, Aymerici, quondam cancellarii, dolis et astutiis ebriati cum nimia festinantia, sicut inter se condixerant, fraudulenter conveniunt, non convocatis neque interrogatis fratribus, contradicente cardinali sanctae Susannae Petro Pisano, qui tunc aderat, seorsum, sicut scriptum est...." The meeting and its subject matter were a violation of church law.The prohibition went back to a constitution legislated by Pope Symmachus in the Roman synod of 499. Andreas Thiel (editor), Epistolae Romanorum Pontificum Genuinae Tomus I (Brunsbergae: in aedibus Eduardi Peter 1868), pp. 641-654, at pp. 645-647: "is quis presbyter aut diaconus aut clericus, papa incolumi et eo inconsulto, aut subscriptionem pro Romano pontificatu commodare, aut pitacio promittere aut sacramentum praebere tentaverit aut aliquod certe suffragium polliceri, vel de hac causa privatis conventiculis factis deliberare atque decernere, loci sui dignitate vel communione privetur". In the event, the committee never met.

When Honorius died, late in the afternoon of 13 February, the cardinals gathered around him did not set their plan into motion. Neither did they inform the cardinals of the Pierleoni faction that the pope had died. Neither did they inform the magistrates of the city of Rome, who only learned of the fact when they assembled after dawn at the church of S. Marco to pay a collective call on the pope.Watterich II, pp. 187-188, from: Historia Compostelana III. 23, from a letter of Cardinal Petrus Pisanus of S. Susanna: "Obeunte itaque papa IV feria post datas cineres circa solis occasum, ostia omnia clausa sunt, et nullus cardinalium est ad eum entrare permissus." Henrique Florez, Espana Sagrada Vol. XX (Madrid: E. Sanchez 1765), p. 515. After nightfall, the body of the dead pope was buried in the cloister of S. Gregorio and S. Andrea, by several laymen, without a funeral service.Zöpffel, p. 336. Watterich II, p. 188: "subito per laicorum manus mortuus miserabiliter defertur; non deponitur feretrum nec ulla ei obsequia fiunt, sed recto gradu... in claustrum trahitur et in vilissimum sepulcrum immergitur." Gregorovius IV, pp. 410-411, who remarks, "The remains of Honorius were scarcely cold, when they were hurried into an open grave in the monastery, in order that the faction here assembled might proceed with the election." Cardinal Petrus Senex, the senior cardinal-bishop, stated firmly, "No mention can be made about a successor until the pope has been buried."Zöpffel, p. 336, with note 226, quoting a letter of Petrus Senex to four cardinal-bishops, in Monumenta Germaniae Historia. Scriptorum Tomus X, p. 485: "haec fuit sententia mea semper, ut nonnisi sepulto papa de successoris persona mentio haberetur." During the night, the cardinals inside the monastery held a meeting at which they elected Cardinal Gregory Papareschi pope. Cardinal Petrus of S. Susanna was present, but had a tart rebuke for the cardinals on that matter: "They gathered themselves together at some altar in the darkness, and, wishing to claim the title to an evil deed, they fabricated for themselves the deacon of S. Angelo as an idol in their rash boldness of zeal."Watterich, pp. 188-189: "colligentes se ad altare aliud in tyenebris, et maledictionis titulum erigere volentes, diaconum sancti Angeli sibi in simulacrum et in idolum zeli ausu temerario fabricaverunt." Gregorovius states, "The proceeding was entirely contrary to law, and Gregory's action was altogether uncanonical.Gregorovius IV, p. 420.

Nonetheless, he supported the election of Pope Anacletus II on the morning of 14 February 1130, and subscribed his electoral decree.Hüls, p. 210, with note 39. Watterich II, p. 185.

Supporter of Innocent II He changed sides, however, late in 1137 or early in 1138. He was impelled, at least in part, by the persuasion of Bernard of Clairvaux.St. Antoninus of Florence, in: Acta Sanctorum Augusti Vol. 4, pp. 164-165: "Abbas Sanctus Bernardus ipsum Petrum Pisanum Papae Innocentio reconciliavit. Post triduum Petrus Leonis impoenitens moritur." Antoninus is wrong as to the interval of time; documentary evidence disproves his statement. Cardinal Petrus Pisanus was reconciled with Innocent II, and signed documents for him on January 8, 1138, which was seventeen days before the death of Anacletus II.Jaffé I, p. 840, and p. 878, no. 7866 (wrongly dated 12 January). Carl Peter Lepsius, Kleine Schriften Vol. I (Magdeburg: Creutz, 1854), pp. 28-29, where the date is "VI Idus. Ianuarii."

From 3 April to 8 April 1139, Pope Innocent held a council at the Lateran, attended, according to Otto of Frising, by more than a thousand prelates.Jaffé, p. 885. During the council, all of the appointments of Anacletus II were declared null and void.Canon XXX: ordinationes factas a Petro Leonis et aliis schismaticis et hereticis evacuant et irritas esse censent." J. D. Mansi (ed.), Sacrorum Conciliorum nova et amplissima collectio, editio novissima, Tomus XXI (Florence: A. Zatta 1776), p. 533. Otto believed that the partisans of Anacletus were anathematized.Otto of Frising, "Chronicon" VII. 23, in: Monumenta Germaniae Historica. Scriptorum Tomus XX (Hannover: Hahn 1868), p. 261: "Proxima media quadragesima synodus maxima circiter mille episcoporum romae, praesidente summo pontifice Innocentio, celebratur; ibique post multa salutifera decreta promulgata scismatici, qui parti Petri Leonis faverant, dampnantur."
