When studying the origins and nature of the Antikythera mechanism, Paul Keyser cautions scholars to be mindful not to “retroject things seen or deduced from one era back into times well prior.”

Biton’s Construction of Machines of War and Catapults describes six machines by five engineers or inventors; the fourth machine is a rolling elevatable scaling ladder, named sambukē, designed by one Damis of Kolophōn. The first sambukē was invented by Herakleides of Taras, in 214 BCE, for the Roman siege of Syracuse. Biton is often dismissed as inc...

Evidence-gathering and model-development always reciprocally reinforce one another: every observation is theory-laden, and correlatively every theory is data-laden. Case studies are transitional, data being licked into model-shape. They may concern a singular event, apparently anomalous, or a repeated event, of an apparently anomalous kind. There i...

Aristotle exploited prior speculations about the kosmos—claims about the elements, the shape of the earth, the heavenly motions, and the causes of things—in order to support his own claims, which he considered the telos of those earlier works. But a mass of evidence exists that those earlier thinkers were speculating within, or on the margins of, a...

Everyone seeks to know their world, hence every culture practices science in some form. In antiquity, several cultures are known to have produced significant science: China, India, Mesopotamia, Egypt, and Greece. The disputatious character of Greek culture drove it to greater activity in science than most cultures; this entry focuses on Ancient Gre...

Ampelius 2.7 explains that Libra honors the inventor of the balance, the puzzling and much-emended personal name MOCHOS. Emendation is unnecessary: "Mochos" is attested as an early Phoenician sage of Sidon, by Poseidonios, and in a translation by the Platonist Ofellius Laetus (ca. 75 CE). Ampelius may have drawn Mochos and Libra from Ofellius, or l...

Callixenus describes a procession of Ptolemy II that was held at midwinter, when both morning and evening stars were visible. Most scholars reject both chronological indications, but they are valid, and securely date the procession to midwinter 279/8 b. c. e. Astronomical observations and discourse were prevalent in early Ptolemaic Alexandria, and...
Article
Le terme grec courant pour « sang », αἷμα, n'a pas d'étymologie reconnue ; les dictionnaires étymologiques de la langue grecque les plus récents rejettent les diverses suggestions-peu convaincantes-qui ont été avancées. Selon moi, une expression nord-ouest sémitique désignant la « vie » en son essence pourrait être à l'origine du nom grec αἷμα. Le...
Article
There are hints in Pliny that the grammarian Apion wrote a work of pharmacy, but the evidence in Pliny is tenuous and somewhat contradictory, and some has even been emended away. Apion is rarely considered a pharmacist, although there are parallels of grammarians—contemporary with Apion—who wrote on pharmacy. Moreover, three overlooked passages pro...

An examination of the word order in which Greek literary texts, up to circa 325 bce , record compound numbers (e.g., “twenty-four”) illuminates two problems: the transmission of numbers in those texts, and the expansion of “commercial” numeracy in Greek society. Compound numbers occur both in descending (“twenty-four”) and ascending (“four and twen...

Two quandaries confront those who study “science” – why do we call some things “science” and others not? and, how can we say, if we can, that “science” makes progress? I will argue that we can simultaneously address both those quandaries by considering under what circumstances science evolves. Science, with technology, exists in some form in every...

Flavian dating formulas and authors of Flavian date are largely absent from the Suda, which suggests a systematic suppression by one of its major sources, perhaps an epitome of Hesychius' Onomatologos.

Semi-structured business processes are emerging at a rapid pace in industries such as government, insurance, banking and healthcare. The workflows underlying these case-oriented processes are non-deterministic. They are mostly driven by human decision making and content status and they may change frequently depending on factors such as economic con...

It is most peculiar that there should be any such thing as Roman science, if by ancient science we mean the sort of thing Greeks did. The genius of Greek science is precisely its weak binding to specifically Greek tradition - making it more readily assimilated by other cultures. There is, however, almost no ancient analogue for assimilators of Gree...

We introduce a concept of multiple dynamic classification, a powerful generalization of single-inheritance OO, and a language Ferret which implements it. Multiple classification allows Male, Female, and Married to be subclasses of Person, arranged so that a single Person object may be both Male and Married, but may not be both Male and Female. Dyna...

Anatolios' Decade is rarely read despite its interest as a document of the transition from late paganism to early Christianity. Dating probably from his tenure as professor in Alexandria, it is the earliest extant work devoted to neo-pythagorean arithmology: the earlier Mathematics of Theon of Smurna only includes a little such material, while mere...

Collecting and organizing all of the architectural information for a system is a challenge faced by information technology (IT) architects. Transforming that information into models of a viable architecture and keeping associated work products consistent and up to date is an even greater challenge. Despite this, model-centric architectural methods...

It was Aristophanes who opened the debate on the reliability of Herodotos, with his spoof in Ach. 526–29 (so far as we can now know). Thucydides entered that arena apparently intending to transform, or possibly transcend, the debate, seeking to position his narrative as more trustworthy than the tales of his fabulous predecessor (1.22–4). Xenophon'...

Science, medicine, and technology seek knowledge to understand or control the natural world. This chapter draws together science and medicine, occupations primarily of the educated elite, with technology often practiced by slaves or foreigners.

We all want to understand the world around us, and the ancient Greeks were the first to try and do so in a way we can properly call scientific. Their thought and writings laid the essential foundations for the revivals of science in medieval Baghdad and renaissance Europe. Now their work is accessible to all, with this invaluable introduction to c....

Hellenistic cometary theory evolved as follows. First, ca. 145–135 B.C.E. Nechepso-Petosiris wrote a book of astrology including a passage on cometary prognosis based on heavenly region of appearance. That work simply assumed that comets were fiery (the standard theory of the era), and that they appear in, move toward, or pause in, any quadrant of...

The proposal for an artificial binary, in an enclosure satellite in geosynchronous orbit, to measure Newton's constant G by the methods of satellite geodesy is reviewed. Several error sources and design difficulties may make more remote the possibility of an improvement in the uncertainty on G (currently about a few parts in 104).

Gravity was measured at eight different heights on a 300-m meteorological tower, using electrostatically nulled LaCoste and Romberg gravimeters. The observed values were corrected for tides, temperature, and gravimeter screw errors, and tested for systematic effects due to (wind-induced) tower motion (no such effects were found). These corrected re...
