Claudius Ptolemy (second century A.D.) was one of the pioneers of trigonometry as well as a major contributor to astronomy, geography, and even astrology. His principal work. Mathematical Syntaxis, known generally as Almagest*, contained an extensive table of lengths of chords in a circle in terms of the angles subtended by the chords.

Configural processing has been considered the major contributor to the face inversion effect (FIE) in face recognition. However, most researchers have only obtained the FIE with one specific ratio of configural alteration. It remains unclear whether the ratio of configural alteration itself can mediate the occurrence of the FIE. We aimed to clarify this issue by manipulating the configural information parametrically using six different ratios, ranging from 4% to 24%. Participants were asked to judge whether a pair of faces were entirely identical or different. The paired faces that were to be compared were presented either simultaneously (Experiment 1) or sequentially (Experiment 2). Both experiments revealed that the FIE was observed only when the ratio of configural alteration was in the intermediate range. These results indicate that even though the FIE has been frequently adopted as an index to examine the underlying mechanism of face processing, the emergence of the FIE is not robust with any configural alteration but dependent on the ratio of configural alteration.

Qiyas (analogy) is one of several methods which had been used by Arabic linguist since the first generation until those who lived in the second century of Hijriyah in formulating Arabic grammars next to Sama' (orally transmitted material). The formulation of the grammars was aimed at conservating Arabic from any kinds of inference, considering that it was not only a mere treasure of the Arab, but also language of Islam after the revelation of Alqur'an. As an ephistemological basis of Arabic synthax, Qiyas serves as an analogy to some eloquent saying of the ancient Arabs. In so doing, Qiyas consists of four components: 1) maqis 'alaih (the source to which one thing is comparred), 2) maqis (the respected object to be comparred), 3) 'illah (the similar aspectls the both share), and 4) hukm (the verdict in search). In terms of it's kind, linguists devide it into three kinds: 1) qiyas al' illah, 2) qiyas at-tard, and qiyas as-syibhi. Even though some linguists argue against the using of Qiyas in formulating grammars, particularly for it is not in line with sima', also for it is considered to be built on subjective rationalisation, Qiyas is of great significance in language theorizing. The significance of Qiyas is not limited to the products demonstrated by traditional linguists. It also applies to our time too, particularly in developing Arabic language in all of it's aspects.

The recent publication of the facsimile edition of MS Paris, Bibliothèque Nationale, Arabe 328a has allowed general access to what is probably one of the oldest, and most important, Qur'an fragments in Europe. The text is unvocalised, but the large number of folios (fifty-six) means that there are enough consonantal variants present to enable a positive identification of the reading represented, which turns out to be that of the Syrian Ibn cĀmir (d. 118/736). This, in combination with the early “Ḥijāzī” script, suggests (a) that this muṣḥaf was copied in Syria, and (b) that this was done some time during the first or early second century AH. In other words, what we have here is almost definitely a muṣḥaf according to the Syrian reading, copied in Syria, at the time when the caliphate had its seat in Syria, i.e. during the Umayyad period. Thus the identification of this particular reading helps in ascertaining the date and provenance of this particular manuscript, as it also fleshes out with documentary evidence the information given in the qirāↄāt literature about this reading.

In the second century, the Roman Emperor Hadrian deified his male lover, Antinous, after the latter drowned in the Nile. Antinous’ worship was revived in the late twentieth century, primarily by gay men and other queer-identified individuals, with Antinous himself being recast as “the Gay God.”

I propose that the notion of possession adds an important ideological nuance to the analyses of iconic books set forth by Martin Marty (1980) and, more recently, by James Watts (2006). Using the early second century BCE book of Sirach as a case study, I tease out some of the symbolic dynamics through which the Bible achieved iconic status in the first place, that is, the conditions in which significance was attached to its material, finite shape. For Ben Sira, this symbolism was deeply tied to his honor-shame ethos in which women posed a threat to the honor of his eternal name, a threat resolved through his possession of Torah figured as the Woman Wisdom. What my analysis suggests is that the conflicted perceptions of gender in Ben Sira’s text is fundamental to his appropriation of, and attempt to produce, authoritative religious literature, and thus essential for understanding his relationship to this emerging canon. Torah, conceived as female, was the core of this canon, but Ben Sira adds his own literary production to this female “body” (or feminized corpus, if you will), becoming the voice of both through the experience of perfect possession.

Resumo: O presente texto objetiva uma abordagem, no interior do pensamento de Ernst Bloch (1885/1977), acerca da relação entre marxismo e utopia: um vínculo incomum no interior do marxismo, comumente tido numa oposição inconciliável. Daí a apropriação do termo “herético” em referência ao marxismo do autor alemão: a expressão é usada não em sentido pejorativo, mas apenas para situar seu distanciamento do marxismo vulgar, bem como sua intenção de crítica radical dessa tradição. Aqui entendemos que é, em particular, por meio da relação entre marxismo e utopia que o pensamento de Ernst Bloch aparece como um projeto inelutavelmente político com vistas a uma filosofia da práxis concreta na principal obra do autor: O Princípio esperança (Das Prinzip Hoffnung) [1954/1959]. Neste livro encontramos, com efeito, a tentativa de pensar a atualidade do marxismo para o contexto do século XX, a era das catástrofes, conforme definição do historiador Eric Hobsbawm. Palavras-chave: Marxismo. Utopia. Dialética. Crítica social. Cultura.  Abstract: This paper presents an approach within the thinking of Ernst Bloch (1885/1977) about the relation between Marxism and Utopia: an unusual link within Marxism, commonly held in an irreconcilable opposition. Hence the appropriation of the term "heretical" in reference to the German author's Marxism: the expression is used not in a pejorative sense, but only to situate its distancing from vulgar Marxism, as well as its intention of a radical critique of this tradition. Here we understand that it is particularly through the relationship between Marxism and Utopia that Ernst Bloch's thought appears as an ineluctably political project with a view to a philosophy of concrete praxis in the principal work of the author: The Principle Hope (Das Prinzip Hoffnung) [1954/1959]. In this book we find, in effect, the attempt to think the actuality of Marxism in the context of the age of catastrophe - as defined by Eric Hobsbawm - that is, the long twentieth century that experienced the extreme barbarism of the concentration camp, of which the thinker in question, Jewish and Communist, managed to escape.  Keywords: Marxism.
