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.

Technical standards are increasingly determining the development, production, trade in and marketing of goods and services. In order to ensure that technical regulations and product standards which vary from country to country do not create unnecessary obstacles to trade the Agreement on Technical Barriers to Trade was adopted during the Uruguay Round. It is paralleled by the Agreement on Sanitary and Phytosanitary Measures which sets out the basic rules on how governments can apply food safety as well as animal and plant health measures without, however, using them as an excuse for protecting domestic producers. Prominent decisions under the WTO Dispute Settlement have interpreted those provisions.
This volume gives a detailed account of the necessary parameters for technical standards and measures seeking to protect health and environment. Included are commentaries on Articles III, XI and XX of GATT 1994 which are equally relevant in this context. The article by article commentaries draw from a considerable body of case law, the work by the TBT and SPS Committee and the relevant legal literature. Attention is given to substantive requirements as well as the necessary standard setting procedures. Apart from a thorough analysis of the relevant and most recent jurisprudence including the Biotech Panel Report the commentary seeks to give answers to newly emerging issues, such as special needs of developing countries. It is an indispensable tool for practitioners and academics working in this field of WTO law.
