OS Grid Ref SD 9732 1713. The Aiggin Stone on Blackstone Edge is best reached via the A58 and is 2 miles to the north-east of Littleborough. This well-defined and quite well-preserved stretch of Roman road going up over Blackstone Edge can be reached on foot, of course, from the A58 and after about half a mile the Aiggin Stone can be seen at the side of the Roman road. Some historians now believe this is a medieval road or trackway that was constructed over the foundations of the Roman road in the 13th century, eventually becoming a packhorse road. The Roman road, if that’s what it really is, with it’s worn flat stones and gulley or channel running down the middle connects MAMUCIUM (Manchester) with VERBEIA (Ilkley) and then EBORACUM (York).
These marker stones or waymarkers were used for religious purposes; travellers would stop at the stone and say a prayer for a safe journey over the bleak, windswept moors. Some of these stones were even used by people carrying coffins; the coffin rested here and prayers for the dead would be recited, perhaps a stone or two placed on top of the cairn as well. Just below the carved cross are two letters I and T which obviously have some religious significance, possibly meaning IN TEDIUM or ‘In the Lord we trust’ or ‘In praise of the Lord’. Near the bottom of the stone some more letters: an I or a T and perhaps ED (In Tedium).
