P.Cair.Arab III 167: A Discussion of the Akhmīm Declaration
Multilingual documents usually are of special historical interest. Their value for the study of the linguistic situation—multilingualism, linguistic inference and the process of arabicisation—in early Islamic Egypt has recently been considered in a number of studies.1 P.Cair.Arab iii 167, a trilingual declaration, written in Coptic, Greek and Arabic, is an exceptionally rich example of such documents. In the present paper, I shall bemainly concernedwith its administrative contents and what it reveals about how the new Arab administration reacted to complaints presented against certain irregularities committed in connection with the tax collection in Akhmīm and its surrounding area. Early Arab rule tended to be practical and keen to avoid any interruption in the smooth running of the administration. It was therefore consistent with the framework of their polity to allow—for at least a century—the perpetuation of two earlier practices: the Byzantine taxation system, and the use of the Greek and Coptic languages in local administration.With regard to taxation, Ibn ʿAbd al-Ḥakam states that “ʿAmr agreed to levy the same amount of taxes as the Rūm (i.e. Byzantines).”2 Consequently, the new Arab administration in Egypt had to deal with the same causes of discontent that had troubled the Romans and the Byzantines before them. Although fiscal pressure had often caused Egypt’s tax-payers to rise in revolt already in the pre-Islamic period, the end of the first/seventh and first half of the second/eighth centuries especially saw tension rising, with more conflicts
Chronological Systems of Byzantine Egypt
Egypt is the richest source of primary documents for the economy, society and everyday life of the late antique Mediterranean world. Its thousands of papyri provide insight into aspects and topics ignored by ancient authors. This handbook is an indispensable tool in navigating these documents, which use a host of complex systems to date legal transactions. Extensive tables and lists help the reader understand the use of consulates, the indiction cycle, eras, and dates by imperial reigns. Other formal aspects of the documents, including Christian invocations and sworn oaths, are also fully covered.
A technique for large-field, superficial electron therapy.
The application of electron beams to radiation therapy has received increased attention in recent years. This interest stems largely from the special characteristics of the electron depth-dose distribution; the fall-off in depth dose near the end of the range of the electrons is particularly rapid for electron beams having energies less than about 10 Mev. Such an electron beam is suitable for the treatment of widespread, superficial lesions, where it is desirable to minimize the dose to deep tissues. All the common sources of super-voltage x-rays, apart from radioactive substances, are inherently capable of producing an external beam of electrons, though with varying degrees of complexity. Electrons of about the energy suitable for superficial therapy (several Mev) may be used to produce an x-ray beam which is sufficiently penetrating for the treatment of even the deepest lesions. The Stanford medical linear accelerator was designed to provide both x-rays and electron beams. The accelerator and its applic...
