In 2006, an Irish bog revealed a 1,200-year-old book with a surprising Mediterranean clue

A routine day spent extracting turf from the wetlands in County Tipperary turned out to be significant for changing our knowledge about book production and trading practices in early medieval times. While using a mechanical excavator to retrieve peat from a bog in Faddan More, one of the workers noticed a peculiar black mass found in the bucket of the excavator. This unexpected discovery immediately marked the end of the operation, transforming the site into an archaeological rescue excavation.As investigators examined the saturated object, they confirmed it was a miraculously preserved early medieval manuscript.The preservation of this particular artefact is a highly unusual occurrence in archaeology. The artefact is formally referred to as the Faddan More Psalter. It is an early medieval Latin Book of Psalms that can be dated back to approximately 800 CE. A significant portion of the book was found in identifiable condition in terms of structural integrity despite having spent over a thousand years buried in waterlogged soil. As a matter of fact, parts of its original vellum pages survived.Uncovering a critical link in early medieval historyThe discovery of this unique manuscript gave scholars rare evidence of early medieval book construction almost instantly, since it offered a physical perspective on how books were produced in an era during which very few of the original book covers still exist. Based on the records kept by the National Museum of Ireland titled The Faddan More Psalter Discovery and Identification, the book had fallen open upon its unearthing to reveal the words in ualle lacrimarum, meaning "in the valley of tears".Until further scientific investigation of this find was carried out, conventional archaeological theory held that materials as fragile as animal skin vellum would either fully disintegrate into liquid or become an untranslatable paste in a waterlogged state after being left in such a condition for hundreds of years. This discovery challenged this longstanding convention about the preservation of objects in a peat bog. As the structural report reveals, even though the pages were extremely fragile, the chemical composition of the bog helped maintain sufficient structure to enable the separation and restoration of each page from one another. How one artefact shed light on international connectionsThe physical characteristics of the manuscript gave researchers more insight into the cultural connections and trade relationships that existed between early Irish monks and their counterparts in the greater Mediterranean region. Rather than examining the document only through the writings contained in it, scientists examined the structural parts of the cover as a distinct form of historical evidence.However, the most remarkable observation was made when examining the wallet-shaped leather cover under the microscope. According to The Faddan More Psalter Contents and Cover by the National Museum of Ireland, the lining layer inside, which was intended to make the leather binding of the book stiffer, contained traces of pure papyrus, a writing material produced only in Egypt and other parts of the eastern Mediterranean during that period. Thus, there is tangible evidence that early medieval Irish monks actively acquired foreign materials, supporting historical theories about contact between the early Irish Church and Mediterranean civilisation.Nowadays, the Faddan More Psalter is one of the best examples of how contemporary technologies can resurrect waterlogged cultural heritage objects that had been considered irrecoverable. The analysis of the complicated process of extracting information from this book proves that ancient environments are natural shelters that can protect details that have not been preserved anywhere else due to dryness. In addition, our knowledge about the technical skills and contacts of ancient peoples is continuously evolving.However, the fact is that although historians often depend on existing libraries in order to trace the travels of ancient communities, the best evidence for the initial foreign interactions of Ireland lay quite hidden just a few inches below the waterlogged peat.
