Technological, elemental and colorimetric analysis of an engraved ochre fragment from the Middle Stone Age levels of Klasies River Cave 1, South Africa

It is generally accepted that abstract and iconographic representations are reflections of symbolic material culture. Here we describe a fragmented ocherous pebble bearing a sequence of sub-parallel linear incisions. These were produced by a lithic point and may represent one of the oldest instances of a deliberate engraving. The object was recovered from Middle Stone Age II levels of Klasies River Cave 1, South Africa, and is dated to between 100,000 and 85,000 years ago. Microscopic analysis reveals that the surface of the object was ground until smooth before being engraved with a sequence of sub-parallel lines made by single and multiple strokes. X-ray fluorescence and colorimetric analysis of the object and a sample of twelve additional ochre pieces from the same level reveals that the brown colour and Manganese-rich composition renders the engraved piece distinct. This suggests that a particular type of raw material may have been selected for engraving purposes. Although the purpose of marking this object remains uncertain, its detailed analysis adds relevant information to previously published occurrences of Middle Stone Age engraved objects and contributes to clarify their distribution through time and space.     

Carneades’ Approval as a Weak Assertion: A Non-Dialectical Interpretation of Academic Skepticism

Academic skepticism is usually interpreted as a type of discourse without an assertion (a dialectical interpretation). I argue against this interpretation. One can interpret Carneades’ notion of approval as our notion of weak assertion and thereby ascribe to him his own views (a non-dialectical interpretation). In Academica Cicero reports the debate about the status of approval as a kind of assent among Carneades’ followers, especially the views of Clitomachus and Philo of Larissa. According to Clitomachus, approving impressions implies acting on them without taking them as true, while according to Philo of Larissa, approval is taking something as true without certainty. In more modern terms, we can say that Philo refers to the notion of weak assertion and Clitomachus to non-assertion. Thus Clitomachus’ reading correlates with a dialectical reading, and Philo’s reading correlates with a non-dialectical reading. Philo’s reading leads to the interpretation of Carneades as a quasi-fallibilist. It is difficult to establish the precise position of the historical Carneades because he was hesitant in his oral teaching. Still, there is some basis in Carneades’ theory for interpreting approval as weak assertion (comprising three degrees of persuasiveness involving rational consideration of what seems to be true). My aim in this essay is thus to argue that a quasi-fallibilist and non-dialectical reading is applicable to the historical Carneades.     

Plant remains and amphorae from the Roman harbour under Flacius Street in Pula (Istria,Croatia)

The aim of this archaeobotanical and archaeological research is to expand knowledge about Roman diet and plant cultivation in Istria and to compare it with similar localities on the Eastern Adriatic coast. We have also tried to find some new information about maritime trade routes in the Mediterranean area in ancient times. Out of 27 samples collected from an excavated Roman port in Flacius Street in Pula, in total, 9809 plant macrofossils were recovered, identified and analysed. The results of the analysis show that most of the plant remains belong to the group of fruit trees and nuts. The most abundant are the remains of Ficus carica, Pinus pinea, Vitis vinifera subsp. vinifera, Rubus fruticosus agg. and Olea europaea subsp. europaea. These are all species that are widespread in the Mediterranean area and have likely always been consumed by the local population. The number of ruderal and weed species found is relatively high (31) in comparison with other plant categories (fruit trees and nuts; fruit collected from the wild; cereals; condiments; oil crops; vegetables and tubers; plants of fresh water environments; elements of maquis), but as they came to the site accidentally and not by targeted human activity, there are far fewer macrofossils of such plants than those of cultivated species. There were a few elements of evergreen forest vegetation and plants of aquatic habitats at the site (2 + 1), which suggests the existence of this type of vegetation in the area of the site in Roman times. Archaeobotanical comparisons of the site in Flacius Street with similar coastal Roman sites—Verige Bay on Veli Brijuni (first-fifth century ad), the port of Zaton near Nin (first-third century ad) and Caska Bay on the island of Pag (first and second century ad)—reveal considerable similarities, confirming the uniformity in nutrition and plant growth in the wider coastal area. Together with the two Roman ships, during the archaeological excavations of the Roman harbour and its layers, we collected over 2000 different archaeological artefacts out of which a large number was almost perfectly preserved. Some of the mentioned artefacts include ceramic amphorae, ceramic table- and kitchenware, ceramic lamps, different usable objects made of glass, wooden use objects, parts of ship’s equipment and other wooden tools, architecture elements from the nearby port as well as residential structures and remains of stone monuments. Because of the large amount of artefacts found at the site, the analysis of the artefacts and data processing are still in progress. As a contribution for recognizing organic remains, we isolated the amphorae whose purpose was the storage and maritime transportation of different food products and ingredients.     

The Dragoman and the Scholar: Two Polish Translations of Saʿdi’s Golestān

This article discusses two Polish translations of Sa?di’s Golestān, prepared by Samuel Otwinowski and Wojciech Biberstein-Kazimirski (alias Albert Kazimirski de Biberstein) and published in 1879 and 1876 respectively. Though edited at the end of the nineteenth century, Otwinowski's translation had been originally completed in the first half of the seventeenth century and is assumed to be the first one or one of the very first renderings of Sa?di's work into a European language. The question that remains unresolved is whether or not Otwinowski's translation, despite being unpublished, was known to seventeenth- and eighteenth-century Polish poets. One can find some stories and motifs “picked” from Sa?di’s Golestān in their poetry, but they seem more likely to have been influenced by non-Polish renderings. This article describes the different translation strategies adopted by the two translators, the literarily gifted dragoman Otwinowski and the nineteenth-century philologist Biberstein Kazimirski.     

The laryngoscope and nineteenth-century British understanding of laryngeal movements

ABSTRACT

The source of the human voice is obscured from view. The development of the laryngoscope in the late 1850s provided the potential to see the action of the vocal folds during speaking for the first time. This new instrument materially contributed to the understanding of vocal fold neuroanatomy, neurophysiology, and neuropathology. The laryngoscope led to elaborated understanding of disorders that previously were determined by changes in sound. The objective of this paper is to detail the consequences of this novel visualization of the larynx, and to trace how it aided in the development of understanding of the movements of the vocal folds. This is demonstrated through an examination of the activities and practices of a group of London clinicians in the second half of the nineteenth century.     

Spatial and temporal dynamics of the urban heat island effect in a small Brazilian city

This study examined the spatial and temporal patterns of the canopy layer urban heat islands (UHI_UCL) in a small city in southeastern Brazil using the local climate zone (LCZ) system. We analysed the influence of weather conditions, LCZs characteristics, and local surface relief on the UHI_UCL magnitudes. Mobile traverses were used to measure air temperatures during representative nights of wet and dry seasons. Daily maximum magnitudes were observed in compact classes (LCZs 3 and 7) under ideal weather conditions (dry, clear skies, and calm) and higher anthropogenic heat release (weekdays). Seasonal effects on LCZ thermal differences were negligible. The peripheral landscapes were warmer than the city centre in both seasons. Among the warmer areas in the city, magnitudes in compact LCZs 3 and 7 were consistently higher than in LCZ 6. In general, representative sites of the main ‘built’ LCZs in the study area exhibit similar inter-zone temperature patterns to those reported for cities of different sizes from tropical and midlatitude regions. Thermal contrasts of ΔT_{LCZ 3 − D} in the study area reveal significant evidence that small cities can have as strong heat islands as bigger cities. These findings highlight the importance of the LCZ system to identify the main controlling factors driving such thermal differences and the need to extend the application of this approach in other South American cities to yield systematic data of UHI_UCL for urban planning given the coming challenges of climate change over the region.
