The church and sexuality in medieval Iceland

Although the Church's regulation of marriage and sex was felt by all Germanic tribes, this subject can be studied most closely in Iceland because of the richness of its source material. Four problems are examined here, from literary, legal, and historical sources, namely marriage, divorce, clerical celibacy and extramarital sex. All three categories of sources agree that marriage was a contractual arrangement between the families of the bride and the groom, as known elsewhere among Germanic tribes. They likewise concur that divorce was possible and easily obtainable. Clerical marriage, among both bishops and priests, was seen as acceptable in the legal and historical sources; the literary sagas do not deal with this issue. That extramarital sexual activities were common, is clear from the legal and historical sources but, in contrast, the literary materials depicts Icelandic couples as largely monogamous and faithful. This discrepancy between the historical and literary sagas, both products of the thirteenth century, can be explained by the growing influence of the Church, which by this time was attempting to introduce clerical celibacy and marital fidelity into Iceland. The thirteenth-century clerical authors of the literary sagas, set in ancient times, provided models intended to improve the sexual behavior of their audiences.     

Soils and palaeo-climate based evidence for irrigation requirements in Norse Greenland

Establishing and sustaining agricultural production was a key factor in the success of Norse settlements during the landnám colonisation across the North Atlantic. In light of the occurrence of channel features in several abandoned home-field areas of the Norse Eastern Settlement of Greenland, and the irrigation requirements of present-day Greenlandic sheep-farmers questions are raised: was irrigation used by the Norse settlers of Greenland on their home-field areas? and, if so, how frequently? Modelling of soil chemical, physical and soil-water hydraulic properties integrated with contemporary high-resolution climatic data demonstrate a frequent requirement for irrigation. Soil moisture deficits are related to the duration and intensity of winter temperature. Using the winter Dye 3 ice core δ¹⁸O record as a climatic proxy, the frequency of moisture deficits, based on comparing mean winter temperatures, indicates that there was a frequent irrigation requirement to maintain home-field productivity, increasing throughout the period of settlement until the 14th Century.     

Studies on amerindian dogs, 1: Carbon isotopes in relation to maize in the diet of domestic dogs from early Peru and Ecuador

Work initiated purely as a dating project in support of a craniometric and morphological investigation of domestic dogs from early Peru has proved to have much wider implications. The stable carbon isotoperatios (¹³C/¹²C) of hair samples from ten dogs show that maize formed a significant part of their diet. Radiocarbon dates for these remains have confirmed that they belong to the period well after the cultivation of maize was first established. Stable carbon isotope measurements can thus be used to test for the presence of maize as a dietary constituent at earlier sites even where there is otherwise only indirect evidence for its cultivation. Collagen from animal or human bone is a suitable alternative to hair for this purpose and the method has been successfully applied to collagen dating to c. 3000 BC from the Valdivia culture site of Real Alto, Ecuador, as well as to a series of early Peruvian dogs.
