This second slate stone (10.24cm l/9.95 w/2.14 h) was found just outside the Middlesex Filter Beds, on the Lea River. Associate Chronocartographers from the Lambent Institute found that this stone also can be traced to a slate mine inside the Snowdonia region. This is the most complex pattern of the four featuring clear-cut lines intersecting several concentric circles. This suggests a possible harmonic structure which distinguishes this blessing from the others. s2.fB likely required multiple instruments and is possible that it featured both percussive and tonal elements.



The image below proposes a digital reconstruction of the engraving and was created using high resolution scanning technology. The reconstruction shows indentations and writings which seems to be largely appropriated from Hildegard von Bingen’s lingua ignota. The descending lines seem to suggest melodic movement, while the circular indentations might represent rhythmic patterns.




The video below is a tour of the Middlesex Filter Beds discovery site. It features an XTR, a device that can detect irregularities in the acoustic composition of terrains and was used to discover all the artefacts in this research.
