Mystery of missing artifacts, solved

Often in science, the fact that some things can not be seen matters more than the fact that some other things can. In addition to large artifacts such as (segments of) roads, aqueducts, buildings, stone walls and chambers, archaeological sites featuring (co-)Roman settlements are usually rich in small artifacts such as jewelry, coins, statues, glass, cookware, pottery, tablets, arms, etc. If indeed Visočica was shaped by man, a logical question arises: Why isn't there such richness in small-sized artifacts found on Visočica too?

Examples of artifacts from metal and Roman eras. Nothing of the sort has been found on Visočica, despite extensive earthwork undertaking.

Apart from trivial explanations (such as that no one has dug deep enough; or that no one has looked in the right places yet; or that the site was looted), the answer is quite obvious within the context itself: the hill's primary intent had been for military and not settlement purposes. Namely, since safety and to it related regularity of the form was the strategic (primary!) task for the peak's occupants, the slopes had to be made flat, clean and unobstructed, and subsequently maintained as such, at all times. In fact, given its primarily military purpose in ancient times, Visočica was most likely an area permanently banned for settling of civilians. What a better proof for this than a total lack of small artifacts (not) found anywhere on the slopes. This is in a dire contrast to what is found on the summit (a National Monument – protected area with remains of Roman and midieval forts) or at the hill's foot, or everywhere around the hill for that matter.

But what about the missing traces of attacks and battles on the Visočica slopes then? Surely enough, all sorts of objects including weaponry and armament, siegecraft equipment in general, as well as stocks of material of any sort, had to be removed both before and after a battle so that the slopes were brought back to its safest state possible - that of total controllability. Finally, instead of some magical "thermal energy steaming from within" explanations, it is exclusively the regular and permanent maintenance of the slopes (for at least a millennium or so!) that can be credited for Visočica being an erosion-free hill. So the maintenance for many centuries is why the central Bosnia’s harsh environment didn't “take care” of the hill's form and then consequently turn Visočica into just another eroded hill of uninteresting looks. It happened simply because man has intervened with nature so as to not allow her to take course...

Finally, it seems plausible that it was precisely the Romans who shaped Visočica, because not only that small-item artifacts from the Roman era are missing (after all the bulldozing earthworks by Osmanagich's followers), but, more importantly, any artifacts from the pre-Roman (stone; metal) eras are practically missing as well! Most likely then, the hill's wasting began with the Ottoman occupation of Bosnia, when Visočica as well as other inner-Bosnia's hills had obviously lost their strategic significance for that has been the first total occupation of the country.

There's no a "Space civilization" magic to Visočica and other apparently shaped Bosnia’s hills. They already represent however a first-class monument to permanent and well-organized attempts at keeping the access to Roman posts (medieval towns) safe from all directions, and at all times. As such, the entire hill too, not just its summit and surroundings, well deserve to be placed on the UNESCO World Heritage List.
