The Catacomb culture (, ) was a Bronze Age culture which flourished on the Pontic steppe in 2500–1950 BC. Originating on the southern steppe as an outgrowth of the Yamnaya culture, the Catacomb culture came to cover a large area. It was probably Indo-European-speaking. Influences of the Catacomb culture have been detected as far as Mycenaean Greece. It spawned the Multi-cordoned ware culture and was eventually succeeded by the Srubnaya culture. Origins The Catacomb culture emerged on the southern part of the Pontic steppe in 2500 BC, as a western descendant of the Yamnaya culture. Influences from the west appear to have had a decisive role on the formation of the Catacomb culture. In addition to the Yamnaya culture, the Catacomb culture displays links with the earlier Sredny Stog culture, the Afanasievo culture and the Poltavka culture. Distribution The Catacomb culture was distributed on the Pontic steppe, an area that had earlier been occupied by the Yamnaya culture. This was a large area, and on the basis of ceramic styles and burial practices, regional variants have been found. On this basis, the Catacomb culture has by some been designated as a "cultural-historical area" with the regional variants classified as distinct cultures in their own respect. In the east the Catacomb culture neighbored the Poltavka culture, which was an eastern descendant of the Yamnaya culture. The Catacomb culture influenced the development of the Poltavka culture. Throughout its existence, the Catacomb culture expanded eastward and northward. Elena Efimovna Kuzmina suggests that the Seima-Turbino phenomenon emerged as a result of interaction between the Abashevo culture, the Catacomb culture and the early Andronovo culture. Evidence of Catacomb influence has been discovered far outside of the Pontic steppe. Its burial chambers, metal types and figurines are very similar to those appearing in Italy and the eastern Mediterranean, while the hammer-head pin, a characteristic ornament of the Catacomb culture, has been found in Central Europe and Italy. Based on these similarities, migrations or cultural diffusion from the Catacomb culture to these areas have been suggested. Similarities between the Catacomb culture and Mycenaean Greece are particularly striking. These include types of socketed spear-heads, types of cheekpieces for horses, and the custom of making masks for the dead. Characteristics Burials The Catacomb culture is named for its burials. These augmented the shaft grave of the Yamnaya culture with burial niche at its base. This is the so-called catacomb.
