This paper examines the use of direct citation in the correspondence between the Egyptian Pharaoh and his officials and his Syro-Canaan vassals in the El-Amarna archive. A frequent phenomenon in the modern and ancient world alike, direct citation serves to support the writer’s claims, lay the blame on or absolve others, demonstrate loyalty, and depict distress. The examples adduced fall into four categories: authoritative, third-party, confirmative, and fabricated/ imaginary speech. Raising the question of the validity of applying modern linguistic theories to ancient sources, these types are analysed in the light of the international diplomacy that flourished in the Fertile Crescent during the 14th-century BCE.

Summary  

Comparing properties of citing and cited source items opens a wide variety of analytical possibilities. In a study of citations among papers in the journal Scientometrics a number of analytical themes are identified. The analysis shows: the way in which a citation graph can be decomposed into different subparts; country specific citation patterns; the effects of self-citations and domestic citations; the mapping of cited author relationships using direct citation and co-citation links; and time slicing effects on impact ranking of countries and papers.
