1150, and the same name appears again later at the Cistercian abbey at Hauterive in what is now Switzerland. Given the extreme eccentricity of the name, it is almost certain these references refer to the same person. Astrolabe is recorded as dying in the Paraclete necrology on 29 or 30 October, year unknown, appearing as "Petrus Astralabius magistri nostri Petri filius" (Peter Astrolabe, son of our magister [master] Peter). Later life Heloise rose in the church, first achieving the level of prioress of Argenteuil. At the disbandment of Argenteuil and seizure by the monks of St Dennis under Abbot Suger, Heloise was transferred to the Paraclete, where Abelard had stationed himself during a period of hermitage. (He had dedicated his chapel to the Paraclete, the holy spirit, because he "had come there as a fugitive and, in the depths of my despair, was granted some comfort by the grace of God".) They now rededicated it as a convent, and Abelard moved on to St. Gildas in Brittany where he became abbot. Heloise became prioress and then abbess of the Paraclete, finally achieving the level of prelate nullius (roughly equivalent to bishop). Her properties and daughter-houses (including the convents of Sainte-Madeleine-de-Traîne (c. 1142), La Pommeray (c. 1147-51?), Laval (ca. 1153), Noëfort (before 1157), Sainte-Flavit (before 1157), Boran / Sainte-Martin-aux-Nonnettes (by 1163)) extended across France, and she was known as a formidable businesswoman. Correspondence Exchange with Abelard The primary correspondence existing today consists of seven letters (numbered Epistolae 2–8 in Latin volumes, since the Historia Calamitatum precedes them as Epistola 1). Four of the letters (Epistolae 2–5) are known as the 'Personal Letters', and contain personal correspondence. The remaining three (Epistolae 6–8) are known as the 'Letters of Direction'. An earlier set of 113 letters discovered much more recently (in the early 1970s) is vouched to also belong to Abelard and Heloise by historian and Abelard scholar Constant Mews. Correspondence began between the two former lovers after the events described in the last section. Héloïse responded, both on the behalf of the Paraclete and herself. In letters which followed, Héloïse expressed dismay at problems that Abelard faced, but scolded him for years of silence following the attack, since Abelard was still wed to Héloïse. Thus began a correspondence both passionate and erudite. Héloïse encouraged Abelard in his philosophical work, and he dedicated his profession of faith to her. Abelard insisted that his
