            "description": " Icelandic scholars copied and translated manuscripts, but fictional literature was present as well: 'But whatever advantages the union with Norway might bring, it produced no new era of development. Intellectual life continuted to flourish, and numerous literary works were written, but but a distinct decline in the quality of literary production becomes noticeable, especially towards the close of the thirteenth century. The old vigor and originality was dwindling, as the growing Christian medieval-time spirit, which was only strengthened throught a closer relation with Norway, was fostering a love for legends and chivalric romances which encouraged copying and translation rather than creative production and original scholarship.' §REF§Gjerset, Knut [1924]. \"History of Iceland\", 208p§REF§ Legal codes and royal letters also became an important tool in the exercise of government, as evidenced in the conflicts between laity and clergy and the associated involvement of the Norwegian crown: 'Upon his return to Iceland Bishop Arni, assisted by Bishop Jörund of Hólar, summoned the people of his diocese to a general council at Skálholt, where he proposed several measures of reform, among others that the churches should be made ecclesiastical property under the control of the bishops. As nearly all churches in Iceland were privately owned, this would involve a change in property rights to which the people would not readily consent. [...] the king's assistance could be invoked. [...] With threats of ban and excommunication he so intimidated the lesser landowners that they suffered to let the smaller churches to pass under ecclesiastical control. But the chieftains who owned the larger churches resolutely resisted. This was especially the case with the churches of Oddi and Hitardal, two of the largest in Iceland. Their owners refused to surrender them; but the bishop caused a decree of transfer to be promulgated at the Althing, threatening the owners with the ban if they resisted. [...] In 1273 King Magnus summoned a council to meet in Bergen to consider a new code of church laws to be proposed by Archbishop Jon of Nidaros, and to deal with other questions touching the relation between church and state. At this council, Bishop Arni, Hrafn Oddsson and the Icelandic chieftains also appeared. In the trial of their case the king as inclined to favor the chieftains, but the archbishop rendered a decision in Arni's favor. His victory was so complete that upon his return home he began to prepare a new code of church laws for Iceland, based on principles suggested to him by Archbishop Jon. The code was adopted at the Althing in 1275 with the understanding that it was later to be ratified by the king and the archbishop.' §REF§Gjerset, Knut [1924]. \"History of Iceland\", 217p§REF§"

While before the war, only a small minority had school education, the Anglican Mission spread its operations to several new stations, including Sasembata, after the war. After the eruption, the scope of education was again greatly extended and it could be said that the eruption marked the beginning of universal school education in the majority of Orokaiva villages. The Sasembata station began to draw virtually the entire child population of the surrounding villages, and most students now follow a five or six year course. While this development had been planned ever since the war, it may be significant that regular school attendance of all the villages in the district was experienced for the first time at Ilimo, where a school was conducted for the whole evacuee child population, and adult classes as well. It is the objective of present school programmes, as far as I can see, to make the population literate and the increase of literacy is a major aspect of acculturation over the period. Literacy has certainly progressed to a point where letters written in Orokaiva to any family in Sivepe can be read and understood with the help of at least a junior member of the family; and can be replied to. While I could see no evidence that people have acquired mathematical knowledge of any sophistication, I was struck by a strong quantitative orientation. In the Orokaiva language, there are no numerals higher than 2; hence, it is the invariable practise to use English numerals when speaking the Orokaiva language. The numerals are, in fact, among the main English linquistic features that have been borrowed. They are used with remarkable frequency; the number of coffee trees, the value in pounds of trade goods included in a bride price, the calculation of money prices, even the number of brothers or men who together played some role in a mythological tale (a distinctly contemporary touch, this)-all these phenomena show that “numbers” have become an integral part of Orokaiva culture. The Orokaiva use the English word “number” for a variety of quantitative concepts, including price. Finally, one must regard as an aspect of acculturation, the introduction of many [Page 80] concepts drawn from the scene of world affairs. While among the Orokaiva, I heard talk about Vietnam, Indonesia, Africa, India. The political orientation displayed was a mild kind of nationalism, and a sense of closeness to newly independent non-white states. But the information, derived from radio broadcasts and speeches by councillors, introduced an acculturative kind of perspective. Its dissemination is being actively encouraged by the Australian authorities.' §REF§Schwimmer, Eric G. 1969. “Cultural Consequences Of A Volcanic Eruption Experienced By The Mount Lamington Orokaiva”, 79§REF§"

            "description": " The Indo-Greeks straddled a crossroads of writing systems and written language traditions. Inscriptions written with the Greek alphabet, use of cuneiform in legal documents and exposure to records in Prakrit are all recorded. Further evidence is found in the Kharosthi inscriptions and the Asokan edicts. Further evidence exist of a transmissions of writing systems to other groups in the North Indian area. §REF§Neelis, Jason.
