Ceramic production in ancient Nasca: provenance analysis of pottery from the Early Nasca and Tiza cultures through INAA

We report the results of an instrumental neutron activation analysis (INAA) undertaken on a regional sample of pottery from the Southern Nasca Region. The samples included specimens primarily from the Early Nasca (ca. A.D. 1–450) and Tiza (ca. A.D. 1000–1476) cultures from a total of 16 different prehispanic sites. The results of the analysis demonstrate centralized production of Early Nasca polychromes and decentralized production of pottery from the Tiza culture. The results of this analysis confirm previous conclusions about the organization of these two indigenous cultures of the south coast of Peru and support the hypothesis of an excess production of polychromes at the ceremonial center Cahuachi for Early Nasca, and multiple centers of production for the Tiza culture.     

New insights regarding the Akko 1 shipwreck: a metallurgic and petrographic investigation of the cannonballs

The Akko 1 shipwreck constitutes the remains of a small Mediterranean naval vessel, discovered in Akko harbour, Israel, and excavated over three seasons between 2006 and 2008. Among the finds at the shipwreck site were eleven cannonballs. Two of them, a 9-pdr and a 24-pdr, were retrieved and studied using metallurgical and petrographic methods. The examination of the cast-iron was performed with optical microscopy, SEM–EDS, XRF and microhardness tests. The remains of the casting sand from within the voids in both cannonballs were studied by petrography. Combined with the archaeological evidence and the historical background, the metallurgical and petrographic testing may suggest that Akko 1 was a warship or an auxiliary naval vessel of similar size to, or slightly smaller than, sixth rate, and was in Akko harbour circa 1840.     

Balanced Bilingualism: Patterns of Contact Influence in L1 and L2 Turkic and Bakhtiari Speech in Juneqan,Iran

Most studies on language contact in Iran have focused on the effects of Persian on the country’s minority languages. There are also many cases where large regional languages such as Azeri, Kurdish, Balochi, Lori and Bakhtiari exert an influence on smaller regional languages, and a few studies have appeared on this topic. This paper examines the effects of language contact in the city of Juneqan in Chahar Mahal va Bakhtiari Province, Iran, where the position of two minority languages—Bakhtiari and Qashqai Turkic—appears to be evenly balanced. The analysis is based on a comparison of L1 and L2 speech from two bilingual individuals with a different L1, as found in responses to the Atlas of the Languages of Iran (ALI) questionnaire. Drawing on examples from lexicon, phonology and morphosyntax, the article argues that the equivalent influence of each language on the first- and second-language speech of members of the other language community is likely achieved not by simple equal status, but through the counterbalancing of regional Bakhtiari dominance with majority mother-tongue Turkic population in this city.     

Obsidian hydration dating on the South Coast of Peru

We compare over 230 obsidian hydration readings from 30 individual site components from the Southern Nasca Region (SNR) with independent age estimates based on radiocarbon dates and temporally diagnostic artifacts. Although there are problems with small sample sizes, and readings must be adjusted for elevation, a very strong relationship accounting for nearly 90% of the total variation in the data set is found. This suggests that obsidian hydration dating (OHD) works in the SNR and is a viable means of independently estimating age. Residual values from our regression suggest that hydration age estimates are usually within 15% of the radiocarbon estimates. Finally, we present an equation other scholars can use to estimate age for Quispisisa obsidian in the SNR.
