Why Eriugena? The Carolingian Empire was full of intriguing characters—disgruntled clerics, dreamers, plotters, and prophets—but one of the most remarkable of those was surely the Irish émigré Eriugena (also known as Iohannes Scottus), who served under King Charles the Bald, grandson of Charlemagne. So unusual was he that we have hardly known what to make of him, his life-story, philosophy, theology, poetry, and philology. But we should. For he offered his quarrelsome contemporaries a different understanding of their troubled times: that behind the many disruptions of the ninth century—Viking raiders, overweening aristocrats, pious and pompous bishops, starving peasants, and proud but distant royals—there was a divine idea or set of them behind all such existences and their ineluctable Return to and into God. In his own time Eriugena was famous as an expert on the Greek language and an influential master of the liberal arts, but he was also a controversial and engaged figure. One of the most striking features of his continental career is that his handwriting has been identified and survives in a number of manuscripts, which allow us a close-up view of how he worked, when, and where. In Eriugena Unbound in a set of twelve essays, new and old, Paul Edward Dutton explores that manuscript evidence to bring us closer to the mind, personality, and historical importance of the enigmatic Irishman. As the Historian says in the dialogue with a Student that opens the work, he does not believe it possible to understand the Carolingians without Eriugena or Eriugena without the Carolingians.

I am most pleased to recommend Trivent publishing to anyone who is at the “publish a book” stage of life. The team is professional, outstanding, supportive, they are intelligent editors who will direct, not coddle, an author on his/her journey to publication.
I have been working with the Philosophical Journal of Conflict and Violence since its debut in 2017. It has been a pleasant experience to see how the papers take shape in the process from submission to peer review to publication. The editor-in-chief together with the Trivent team do a tremendous job and are always seeking quality above all!
I’ve participated in two conferences organized by Trivent in the last few years and both were a nice experience – went smoothly and had decent talks in good spirit. When it came to managing manuscripts, I was surprised by the professionalism by which they helped my text get published. I definitely enjoyed working with them!
