The Astrolabe

An ancient instrument for solving problems of location and distance, as well as time

Astrolábon órganon is the word used in Ptolemaeus Syntaxis 5.1 to describe a form of armillary sphere consisting of both fixed and rotating rings for determining the ecliptic co-ordinates of stars. Also called astrolabe were two-dimensional representations of the celestial sphere: over fixed disks with a representation of the horizon of the earth (in each case for a specific geographic latitude) and its parallels up to the zenith lies a rotating representation of the heavens (called ‘spider’ or ‘net’) with zodiac and indicators for some of the brightest stars. On the back is an indicator (‘alidade’) with visor plates for calculating the height of the stars. The astrolabe allows its user to determine the hours of day and night, the positions of stars, and the height and depth of objects on earth (mountains, buildings, wells). The oldest extant descriptions of the flat, planispheric astrolabe come from Iohannes Philoponus, 6th century AD, and (in Syrian) from Severus Sebokht, c. 660 AD. Indirect references may date back as early as Theon (4th cent.). Between the 8th and the 9th centuries the Arabs appropriated the knowledge of the astrolabe. At the end of the 10th century and again in the 12th century, they passed it on to Western Europe, where astrolabes were constructed up until the 17th cent. Today, one Byzantine astrolabe (from 1062) is extant, as are some 750 Arabic-Islamic astrolabes and approximately the same number of European astrolabes.

'Including this book as an available resource will enhance any library and the ability to point to practical resources in the field' - Newsletter American Society of International Law

‘excellent contributions and a high standard of quality’ - Journal of International Law of Peace and Armed Conflict

International Peacekeeping is devoted to reporting upon and analyzing international peacekeeping with an emphasis upon legal and policy issues, but is not limited to these issues. It is recognized that in today's world there is a wealth of information available from the internet and through other sources. It is therefore the goal of this Yearbook to make this information available in one publication which both organizes and records events over the course of a year through analytical articles, a chronicle, primary documents, and a bibliography. Topics include inter alia peacekeeping, peace, war, conflict resolution, diplomacy, international law, international security, humanitarian relief, humanitarian law, and terrorism. The Yearbook is of scholarly quality but is not narrowly theoretical. It provides the interested public -- diplomats, civil servants, politicians, the military, academics, journalists, NGO employees, and serious citizens -- with a document of record, comment, and a starting point for further research on peacekeeping and related topics. This is achieved not only by the provision of 'basic documents' (on CD ROM), such as Security Council Resolutions and Reports of the UN Secretary- General, but also by expert commentaries on world events. Peacekeeping is treated in a pragmatic light, seen as a form of international military cooperation for the preservation or restoration of international peace and security. Attention is focused not only on UN peacekeeping operations, but other missions as well. This Yearbook is the continuation of the journal International Peacekeeping.
