Rose Cottage Cave (RCC) is an archaeological site in the Free State, South Africa, situated only a few kilometers away from Ladybrand, close to the Caledon River, on the northern slopes of the Platberg. [1] RCC is an important site because of its long cultural sequence, its roots in modern human behavior, and the movement of early modern humans out of Africa. Rose Cottage is the only site from the Middle Stone Age that can tell us about the behavioral variability of hunter-gatherers during the Late Pleistocene and Holocene. [2] Berry D. Malan excavated the site between 1943 and 1946, shortly followed by Peter B. Beaumont in the early 1960s, and the most recent excavations occurred from 1987 to 1997 by Lyn Wadley and Philip Harper in 1989 under Wadley's supervision. [3] Humans have inhabited Rose Cottage for over 100,000 years throughout the Middle and Later Stone Ages. Site formation and sediment formation processes at Rose Cottage appear to be primarily anthropogenic. [4] Archaeological research focuses primarily on blade technology and tool forms from the Middle Stone Age and the implications of modern human behavior. Structurally, the cave measures more than 6 meters (20 feet) deep and about 20 by 10 meters (66 feet by 33 feet). A boulder encloses the front, protecting the cave, but allowing a small opening for a skylight and narrow entrances on both the east and west sides. [1]

Archaeological excavations

The extensive excavation sequence at Rose Cottage dates to Berry Malan in the 1940s. Shortly after, Peter Beaumont excavated the cave in 1962. [5] Both Malan and Beaumont yielded LSA and MSA materials. The most recent explorations, from 1987 to 1997, were led by Lyn Wadley. In 1989, Philip Harper also contributed to excavations involving extensive analyses of lithic assemblages under Wadley's supervision. [6]

Malan

In the 1940s, Malan began excavations at Rose Cottage Cave. He explored a vast extent of the cave and excavated in 3-inch (76 mm) spits. [5] Depending on the order and relative position of strata and the homogeneity of the natural sediment, some spits measured to depths of 6 to 9 inches (150 to 230 mm). Unfortunately, the spits distorted cultural sequence boundaries and thus complicated the correlation between collections and various excavations. [4] Malan excavated a sizable expanse of the upper levels of the site, but only five squares (measured in yards) deep into the MSA layers.

During his excavations, Malan collected MSA ochre from Rose Cottage, but only kept pieces he thought significant. Malan never analyzed his artifacts, but Wadley and Harper conducted a study of the recovered lithics more than 40 years later and observed intermittent occurrences of lithic chunks and chips. [3] These erratic frequencies may have occurred because Malan did not methodically store all artifacts. The frequent appearance of ochre pieces in Malan's collection, specifically small fragments with no discernible evidence of use detrition, is also likely the effect of his irregular collection practices. [7] Malans' ochre collection included 84 definite and 25 potential pieces of ochre. The oldest layers contained the highest percentage of ochre pieces, while the post-Howiesons Poort layers contained the lowest ratio. A detailed examination of scored ochre collected from the oldest MSA layers suggests unpractical scoring, but instead possible engravings. [8]

Despite the importance of the cave, Malan ceased his excavations in 1946 and performed no further explorations of the site or the collected materials. In 1952, Malan released a publication consisting of preliminary observations. [7] He interpreted the extensive Stone Age sequence as Wilton, Pre-Wilton, MSA, and a three-phase Howiesons Poort. [5]

Beaumont

In 1962, Beaumont re-excavated Rose Cottage Cave to collect samples of charcoal for radiocarbon dating, a method not yet developed during Malan's excavations. The collected charcoal samples confirmed the antiquity of the cave and provided several dates from the LSA and MSA layers. [9] The upper layers contained ceramics dating to 1100 BP (+/- 30). Beaumont presented an additional industrial period, the Early Later Stone Age (ELSA) industry, ranging between 29,000 BP and 40,000 BP. The ELSA correlates to strata between 1 and 3 meters deep. [10] However, it is almost impossible to compare layers of the cave based solely on depth due to the sloping of the cave deposits. Beaumont never published his excavation results. [4]

Wadley

Lyn Wadley spent eleven years conducting large-scale excavations at Rose Cottage Cave. Wadley excavated a sizable extent of the site but dismissed her digs in the upper MSA layers to focus on LSA occupation and carry out spatial analysis. The first steps of her excavation process included clearing out and sandbagging the old sections of the collapsing cave walls. [11] She then constructed a 20-quadrant grid and excavated to depths of about 0.5 meters (20 inches) in the undamaged parts of the cave. Wadley, with the assistance of Harper, executed extensive analyses of lithic assemblages. The accumulations substantially include fine-grained opalines, which were likely washed down by mountain streams from the Drakensberg basalts into the Caledon River, located approximately 10 kilometers from the site.

Wadley also collected charcoal samples intended for environmental analysis. The collected charcoal samples resulted in two unique vegetation patterns: one that corresponds to the Holocene and one to the Late Pleistocene. [11]

Site formation

Sediment peels from Rose Cottage Cave preserve unique materials and provide a record for site formation processes. [12] A detailed examination of the sediment peels, coupled with Fourier transform infrared spectroscopy, demonstrates an abundance of sand- and silt-sized quartz grains. A small gap in the cave likely allowed for the entrance of these quartz grains. In parts of the cave, sediments measure more than 6 meters (20 feet) deep. [3] These deposits were formed chiefly from the weathering of the sandstone walls and roof of the cave and materials washed in by rainfall.

Deposits of burnt bone, charcoal, lithic fragments, fat-derived char, and ashes indicate that Rose Cottage has rich anthropogenic contributions to the formation of the site. [12] Slow, continuous downslope creep has produced an accumulation of loose, unconsolidated sediment deposits at the base of the cave. The buildup of these remains, combined with animal and plant disturbances, has homogenized much of the sediment deposits. [13] Evidence of well-preserved bedding and sedimentary structures containing physical remains of fire is rare but is occasionally present in the sediment peels.

Clay-coated artifacts indicate the downward flow of water over the sequence, which is probable reasoning for the poor preservation of bone and ashes at Rose Cottage Cave. [3] Sand and silt laminae and accumulations of coarse residual material left in the channel by the normal processes of the stream are observable in sediment peels dating from between 60 and 35 ka BP. These remains suggest an environment with high-energy sediment and frequent flooding, causing underlying deposits to erode and depositing newer sediment in large volumes. [3] This environment explains the fluctuating presence of artifacts in the post-Howiesons Poort layers and implies human activity at Rose Cottage Cave during this period.

Technological innovations

The Middle Stone Age dates to ages between around 96,000 and 30,000 years ago. Optically stimulated luminescence (OSL) for sediments and thermoluminescence (TL) for burned artifacts were used to derive these MSA ages. These ages denote approximately 60,000 years of MSA occupations at Rose Cottage Cave. During this period, blade technology and tool forms appeared at Rose Cottage Cave, suggesting episodes of ingenuity and innovation. The MSA tool assemblages include the recognizable Howiesons Poort industry (within which progressive variation is observable) and earlier and later MSA groupings. [14] The Howiesons Poort layers are discernible by the occurrence of various backed tools (crescents and lunate segments), obliquely backed blades (truncations), backed blades, thin blades, and bladelets.

Howiesons Poort industry

The Howiesons Poort pieces are a variety of small geometric blades used as inserts in composite weapons. [15] Composite tools signify a unique model in tool production and imply a progressive cognitive state. These multi-component tools were held together with complex pastes prepared from red ochre combined with plant gum. [6] The term ochre describes a group of rocks that are usually carbonates of iron and have partially or wholly replaced limestone. Rose Cottage Cave Howiesons Poort encompasses an evolving classification of three phases: the pre-Howiesons Poort (pre-HP) phase, the Howiesons Poort (HP) phase, and the post-Howiesons Poort (post-HP) phase. These phases exhibit considerable changes in the length, shape, and thickness of the tools throughout time. [7] Further analysis of these phases revealed a consistent trend toward smaller flake blades and flakes. However, the pieces all exhibit the central characteristics of a "classic" Howiesons Poort. The Howiesons Poort technology is evidence of developed hunting technologies with possible social and symbolic connotations. [16]

Ochre evidence

No sources of ochre occur in or around Rose Cottage Cave, yet the site has an extensive record of ochre collection and use. Excavations at Rose Cottage provide evidence of ochre use for over sixty thousand years. [17] Pieces of ochre were first collected from the cave by Malan, later followed by Harper. Ochre pieces differ in color, grain size, geological type, and hardness. [17] Red is associated with hematite rich ochre and yellow with goethite. Much of the excavated ochre had silty or clayey grain sizes.

The post-Howiesons Poort layers proved to be the most abundant in ochre pieces, but the Howiesons Poort layers had the highest ochre frequency per sediment volume. The utilization rate of ochre was highest in the pre-Howiesons Poort layers. [18] The properties of the ochre pieces excavated from Rose Cottage Cave from the Middle Stone Age (MSA) indicate evidence of surface modifications. This evidence suggests that these early artisans did not simply color their pastes red but instead intentionally affected their physical appearance through chemical changes. [19]

Ochre use

The use of the term ochre" instead of coloring material or pigment prevents assumptions of ochre use. New analyses of ochre groupings from Rose Cottage Cave improve our understanding of ochre use throughout the MSA. Archaeological evidence and finds of orche demonstrate use to a certain degree. [20] People at Rose Cottage Cave used ochre for rubbing, grinding, and instances of scoring. The rubbing technique directly transfers red powder from ochre onto surfaces like animal hide and human skin. [18] Rubbing is appropriate for purposes such as coloring, marking, or protecting skin or hide (from bacteria, insects, or the sun). Evidence suggests that early artisans purposely colored and wore suspended ochre and ochre in pierced shells. The grinding of ochre produces a red ochre powder that, when combined with water, is useful for several tasks such as cosmetics, ochre-based paint, or ochre-loaded adhesives. [18] The kinds of ochre selected are contingent upon the time restrictions of some of the processes and techniques and the implied uses of ochre. Engraved ochre found in burials implies a potential symbolic connotation. [20]

Cultural innovations

Excavations at Rose Cottage Cave suggest evidence of cultural modernity, such as the storage of symbolic materials. Dark-grey, fine-grained deposits, proving rich in organics, are believed to be composed of decaying plant and animal materials likely discarded by occupants. [19] Sediments from Late Pleistocene and Holocene layers show that deposits collected from inside the RCC are extremely C3 compared with deposits from outside, which are exceptionally C4. The C3 sediments from inside the cave must incorporate materials brought into Rose Cottage by its inhabitants, such as edible plants, leaves for bedding, and firewood.

Environment

The environment of Rose Cottage Cave is primarily a sub-humid, summer precipitation area with occasional winter rainfall. [3] Rose Cottage lies within the Caledon River corridor (measuring about 50 kilometers (30 mi) wide), which, in comparison with the surrounding areas, experiences moderately severe winter frost. The cave is positioned facing northward; consequently, it is warmed by the sun during the winter months and cool in the summer. The surrounding vegetation is mainly Cymbopogon-Themeda grassland. [21] This veld is fecund after rain showers; however, the grazing period is only six months out of the year. The open rural plains of the cave are mainly drab grasslands strewn with patches of scrub thicket, bush, and rocky sandstone hill slopes.

Behavioral modernity is a suite of behavioral and cognitive traits that distinguishes current Homo sapiens from other anatomically modern humans, hominins, and primates. Most scholars agree that modern human behavior can be characterized by abstract thinking, planning depth, symbolic behavior, music and dance, exploitation of large game, and blade technology, among others. Underlying these behaviors and technological innovations are cognitive and cultural foundations that have been documented experimentally and ethnographically by evolutionary and cultural anthropologists. These human universal patterns include cumulative cultural adaptation, social norms, language, and extensive help and cooperation beyond close kin.

Wilton is a term archaeologists use to generalize archaeological sites and cultures that share similar stone and non-stone technology dating from 8,000-4,000 years ago. Archaeologists often refer to Wilton as a technocomplex, or Industry. Technological industries are defined by a common tradition of stone tool assemblages, but these technological industries extend to common cultural behaviors. As such, archaeologists use these industries to define a discrete cultural taxonomy. However, technological industries have the potential to generalize different cultures and communities at regional scales that, in more local settings, are distinguishable in both technology and cultural behaviors.

<span class="mw-page-title-main">Middle Stone Age</span> Period in African prehistory

The Middle Stone Age was a period of African prehistory between the Early Stone Age and the Late Stone Age. It is generally considered to have begun around 280,000 years ago and ended around 50–25,000 years ago. The beginnings of particular MSA stone tools have their origins as far back as 550–500,000 years ago and as such some researchers consider this to be the beginnings of the MSA. The MSA is often mistakenly understood to be synonymous with the Middle Paleolithic of Europe, especially due to their roughly contemporaneous time span; however, the Middle Paleolithic of Europe represents an entirely different hominin population, Homo neanderthalensis, than the MSA of Africa, which did not have Neanderthal populations. Additionally, current archaeological research in Africa has yielded much evidence to suggest that modern human behavior and cognition was beginning to develop much earlier in Africa during the MSA than it was in Europe during the Middle Paleolithic. The MSA is associated with both anatomically modern humans as well as archaic Homo sapiens, sometimes referred to as Homo helmei. Early physical evidence comes from the Gademotta Formation in Ethiopia, the Kapthurin Formation in Kenya and Kathu Pan in South Africa.

Howiesons Poort is a technological and cultural period characterized by material evidence with shared design features found in South Africa, Lesotho, and Namibia. It was named after the Howieson's Poort Shelter archaeological site near Grahamstown in South Africa, where the first assemblage of these tools was discovered. Howiesons Poort is believed, based on chronological comparisons between many sites, to have started around 64.8 thousand years ago and ended around 59.5 thousand years ago. It is considered to be a technocomplex, or a cultural period in archaeology classified by distinct and specific technological materials. Howiesons Poort is notable for its relatively complex tools, technological innovations, and cultural objects evidencing symbolic expression. One site in particular, Sibudu Cave, provides one of the key reference sequences for Howiesons Poort. Howiesons Poort assemblages are primarily found at sites south of the Limpopo River.

Howieson's Poort Shelter is a small rock shelter in South Africa containing the archaeological site from which the Howiesons Poort period in the Middle Stone Age gets its name.

There were preserved starch grains on many of the stone tools as well. Overall, this site can help add to our knowledge of the Middle Stone Age site in the Niassa valley and to our understanding of the subsistence of Middle Stone Age peoples in Eastern Africa as a whole.

Porc-Epic Cave is an archaeological site located in Dire Dawa,Oromia, Ethiopia. Dated back to the Middle Stone Age, the site contains extensive evidence of microlithic tools, bone, and faunal remains. The lithic assemblage reveals that inhabitants at the time were well-organized with their environment. There is also rock art and strong evidence for ochre processing. The site was first discovered in 1920 by H. De Monfreid and P. Teilhard De Chardin. H. Breuil and P. Wernert performed the first excavation in 1933, followed from 1974 to 1976 by J. Desmond Clark and K.D. Williamson. Succeeding this was an excavation in 1998. Porc-Epic Cave provides insight into the behavior and technical capability of modern humans in eastern Africa during the Middle Stone Age.
