Thank you for the music: Love is ... the oldest, yet the latest thing

To paraphrase Lewis Carroll's "Alice", all this jumping back and forth in time makes one quite giddy! I used to think it was bad enough when I woke up in the morning and couldn't remember where I was. Now I have to think "when am I?"
And as if that wasn't enough, I almost didn't get to go with the excursion I had requested. Madame director wanted me to go to France at the beginning of the seventeenth century, while I wanted to follow the link back from John of Salisbury.
In the end I managed to convince her of the value of the trail I was following, and since the technicalities make it impossible to travel to the same place and time more than once, my request was reluctantly granted. And so it is that I find myself in the company of some of the most extraordinary minds ever to gather in a single place:

Here, in 1139, at the Abbey of St.Gildas-de-Rhuys in Brittany, Father Abbot Pierre Abelard takes time from his monastic duties to engage students from some of the furthest reaches of the known world in philosophical and religious debates.
I am surprised (but perhaps, unfairly so) that among the young men who attend so eagerly and listen so attentively to his discourses, are several dark faces with features suggestive of Arab, or Indian heritage. I would have thought that differences in religious belief might have deterred these fellows from aspiring to learn from someone who is now known as much for his sermons as for his rhetoric and knowledge of classics.
Of course, Pierre Abelard was not always a friar. As a young man, quite apart from his promise as a scholar, he had opportunity to indulge his appetites at the various hostelries that catered to the students of Notre Dame university in Paris, but it seems physical pleasures were generally less enticing than intellectual ones. Until, that is, he got to know Heloise, a most unusual young woman taking full advantage of her uncle's guardianship to study alongside the menfolk.
The unhappy outcome of their relationship was that Heloise was compelled to enter holy orders, while Abelard was castrated by her uncle! But not before Heloise had conceived a child.
Despite their forced separation, it seems their love for one another never died.
In tribute to one of the great love stories of all time (for more information, I recommend the tale of Abelard and Heloise), I would like to reproduce in modern notation, the chant of Abbess Hildegard von Bingen, received recently at this abbey with other correspondence.
