The initial phase is represented by the central pit grave within the ﬁrst mound of the Gruda Boljevića tumulus. This initial burial was dated to the beginning of the third millennium BC. Culturally it belongs to the southwestern branch of the Yamnaya culture, characterized by pit grave burials.
The next phase in the Copper Age tumulus development are represented by Velika Gruda and Mala Gruda tumuluses, which was dated to the period between the 3000 and 2800 BC. Mala and Velika Gruda tumuluses also have central pit burial. But this time the body was not placed directly into the pit. First a shallow grave pit was dug into the earth to the depth of half a meter. Then a stone cist was built inside the pit. First the bottom of the grave pit was covered with a stone plate and then the vertical stone plates were placed on top of it to form the dolmen cist. The body was placed inside the stone cist and then the cover stone plate was placed on top of it. The stone dolmen cist which was sticking out of the pit was then covered with a tumulus pile.
1. a central position of the burial within a large multi layered tumulus with stone curb
2. a cross in circle symbol inscribed either on a golden disc which topped the axe shaft hole or on ceramic vesel, which was interpreted as thurible and which was part of a special funerary ceramic set.
3. placing of food vessels inside the burial
These common elements show clear cultural continuity.
But at the same time the actual burial underwent a significant change:
1. a burial inside a pit with or without a cist dug into the ground
2. a burial inside a cist sticking out of a pit which was dug into the ground
3. a burial inside a free standing cist built on the surface of the ground.
This shows clear cultural development.
So by 2500 BC in Montenegro we find massive stone burial dolmen like cists which were placed on the surface of the ground and then covered by multi layered earth tumuluses with stone curbs.
In my previous posts about Montenegrian tumuluses, I already discussed the possibility that the Irish Annals contain records describing the arrival in the mid 3rd millennium BC, of the first metallurgists to Ireland from Montenegro. The finding of golden cross discs in both Montenegro (early 3rd millennium BC) and then in Ireland (late 3rd millennium BC), and the latest genetic data (which I will discuss in one of my future posts) seem to confirm this.
So there is definite observable cultural influence brought to Ireland by immigrants from Montenegro in the mid 3rd millennium BC.
But was there, at the beginning of the 3rd millennium, a previous cultural influence brought to Montenegro by people who emigrated from Ireland?
Is it possible that the cultural process of "raising" of burial cists from the ground, which happened in Montenegro in the first half of the 3rd millennium BC was influenced by these Irish immigrants? Or did the Montenegrian immigrants arrive to Ireland in several waves, the first wave arriving before 2800 BC and the second wave arriving around 2500 BC?
I will talk more about this in my next post.
