Stable carbon and oxygen isotopic compositions of wood ash: an experimental study with archaeological implications

Wood ash, composed mainly of the mineral calcite, is an important component in many archaeological sites. Identification of wood ash in the archaeological record is often difficult due to mixing of ash with other calcitic components of geogenic origin and/or due to diagenetic changes. A recent empirical study using the stable isotope compositions of carbon (δ¹³C) and oxygen (δ¹⁸O) in wood ash enabled the identification of mixtures of wood ash with geogenic calcite and to follow diagenetic changes due to partial dissolution and re-precipitation of ash in two prehistoric cave sites in Israel. Little however is known about the processes responsible for the isotopic compositions of wood ash in relation to formation at various temperatures and the influence on isotopic composition of ash from a variety of plant species. Here we present an experimental study of wood ash formed by burning three C3 tree species and one C4 desert bush at different temperatures. The results indicate that there are significant differences in the isotopic compositions of carbon and oxygen between wood ash that forms by combustion at a relatively low temperature (500 °C) and at a higher temperature (900 °C). In addition, we show that the isotopic composition of carbon and oxygen in high temperature wood ash approaches equilibrium over a period of several months and that the carbon isotopic composition of low temperature wood ash may reflect the photosynthetic pathway of the burnt woody species. Lastly, we show that the isotopic compositions obtained from wood ash prepared at different temperatures do not reflect a temperature dependent fractionation process, but a mixing line between calcite that formed by low temperature combustion and calcite formed by high temperature combustion which later underwent re-carbonation with atmospheric CO₂. In addition, we suggest that exchange processes may possibly occur during combustion between decomposing calcium-oxalate and atmospheric O₂, CO₂ and CO. The archaeological implications of this study are discussed in relation to identification of wood ash in the archaeological record, identification of fuel sources and burning temperatures, and diagenetic changes expected in karstic cave environments. The method presented here can be applied at any archaeological site.     

The Italian colonial cinema: Agendas and audiences

In 1997, Italy's leading politicians began the overdue process of revising the existing constitution. The bicameral commission of parliament charged with this task has proposed significant alterations to the country's institutional structure. Innovations include a directly elected presidency, an end to bicameralism and a greater role for sub‐national tiers of administration. However, this article argues that the suggested changes are in fact less sweeping than they seem, and do not address the country's urgent need to move towards a more competitive form of democracy.     

Editorial

For John Stuart Mill, Matthew Arnold, and their later Victorian respondents, the Stoic writer and second-century CE Roman emperor Marcus Aurelius represented a test-case for the sufficiency of the ostensibly masculine practices of askesis and detachment as ethical ideals, specifically in the context of Christianity. A brief passage in Mill's On Liberty (1859) comparing Stoic ethics with Christian ethical practice provoked an extended response from Arnold in an 1863 review essay. Mill and Arnold both used comparisons with Christianity to trace the contours and to explore the limits of Marcus Aurelius's ‘lovable’ nature; in doing so, Arnold in particular enacted a peculiar kind of historical sympathy for both the Marcus Aurelius that was and for a missed rapprochement between classical and Christian ethics. For a series of later writers, including freethinkers, religious conservatives and liberal Christians, Marcus Aurelius either promised or threatened to reconcile Stoicism with Christianity. Assessing the emperor in the light of Christianity became a means both for producing or denying a link to the classical past and for describing the condition of Christianity in England. A key point of contention for these writers and a landmark in the broader debate over Victorian secularization was the question of Marcus Aurelius' role in the torture and killing of 48 Christians at Lugdunum (Lyons) in 177 CE.
