Abstract:

AbstractIn 360/359 BC, Kotys, king of the Odrysian Thracians, was killed by two brothers of Ainos. Confusion, however, soon arose around their identity. The aim of this article is to reconstruct and analyze the various traditions that spread in Antiquity about their identification. Demosthenes was the first to call the murderers Python and Herakleides of Ainos. His version of the facts was later followed by Philodemos, Plutarchos, and Philostratos. Aristoteles, however, called them Πύρρων (or Πάρρων) and Herakleides of Ainos. Diokles of Magnesia, probably following the same tradition as Aristoteles, confused Pyrrhon of Ainos with Pyrrhon of Elis. Similarly, Demetrios of Magnesia confused Herakleides of Ainos with Herakleides Pontikos. Finally, the figures of Kotys, Herakleides, and Python were perhaps reused by the author of the spurious Letters of Chion of Herakleia and recontextualized as symbols of the conflict between philosophy and tyranny.

Abstract:

O objetivo deste artigo é examinar a temática das paixões no interior do Pirronismo antigo, especialmente nas figuras de Pirro e Sexto Empírico. Tal questão é controversa em um debate sobre o ceticismo antigo, em especial, porque essa corrente não pode dispor de uma teoria das paixões, dado que elas nada afirmam sobre o mundo. Entretanto, é possível falar que o cético manifesta sentimentos, ainda que de uma maneira não teórica? Para investigarmos essa nuance, passaremos pela vida de Pirro – conforme descrita por Diógenes Laércio – e pelo Esboços do Pirronismo de Sexto Empírico, em busca de uma reflexão acerca das paixões no interior do ceticismo pirrônico.PALAVRAS-CHAVES: Pirro. Sexto Empírico. Paixões. Ceticismo. Diógenes Laércio. ABSTRACTThe purpose of this paper is to examine the passions within the ancient Pyrrhonism, especially in the figures of Pyrrho and Sextus Empiricus. This question is controversial in a debate about ancient skepticism, especially because the skeptics cannot have a theory of passions, since they claim nothing about the world. However, is it possible to speak that the skeptic expresses feelings, albeit in a non-theoretical way? To examine this question, we will go through the life of Pyrrhus - as described by Diogenes Laertius – and we will examine the Outlines of Scepticism by Sextus Empiricus in search of a reflection on the passions within the Pyrrhonic skepticism.KEY-WORDS: Pyrrho. Sixth Empiricus. Passions. Skepticism. Diogenes Laertius.

Abstract:

It has been generally agreed for some time that the best piece of extant evidence for Pyrrho's thought is contained in a section of Eusebius' Praeparatio evangelica (14.18.1–4 = T53 Decleva Caizzi) where Eusebius cites Aristocles of Messene's πεϱὶ ϕιλοσοϕίας book eight, where Aristocles in turn cites Timon on Pyrrho. But there the agreement stops. The wealth of recent writing on this very short passage provides evidence of its difficulty. Ausland, Bett, Brennan, Brunschwig, and Stopper have all within the last ten years or so offered their own various interpretations of these dozen lines of Greek text.

Abstract:

AbstractI offer reasons against reading Hume as a Pyrrhonian sceptic. I argue that Hume's scepticism is motivated differently, that his sceptical strategies are not analogous to Pyrrhonism's, and that it is profitable to read Hume as a critic of Pyrrhonism. I hold that the most informative point of comparison between Hume and Sextus Empiricus is a point of difference, namely, their stands on the connection between suspension of judgement (epochê) and tranquillity (ataraxia). For Sextus, tranquillity flows naturally from suspending judgement on all opinions. Hume, by contrast, consistently treats radical suspension of judgement as resulting in despair and social detachment. I take a firmer stance than past commentators on this issue by affirming that Hume and Sextus do not merely disagree on this issue, but that Hume's view is more plausible. Reading Hume's sceptical crisis, I propose, reveals an insightful criticism of Pyrrhonism, one that sheds light on human nature's response to radical doubt.

Abstract:

Heterocyclic chalcones are a recently explored subgroup of chalcones that have sparked interest due to their significant antibacterial and antifungal capabilities. Herein, the structure and solubility of two such compounds, (E)-1-(1H-pyrrol-2-yl)-3-(thiophen-2-yl)prop-2-en-1-one and (E)-3-phenyl-1-(1H-pyrrol-2-yl)prop-2-en-1-one, are assessed. Single crystals of (E)-1-(1H-pyrrol-2-yl)-3-(thiophen-2-yl)prop-2-en-1-one were grown, allowing structural comparisons between the heterocyclic chalcones and (2E)-1,3-diphenylprop-2-en-1-one, trivially known as trans-chalcone. The two heterocyclic chalcones were found to be less soluble in all solvents tested and to have higher melting points than trans-chalcone, probably due to their stronger intermolecular interactions arising from the functionalized rings. Interestingly, however, it was found that the addition of the thiophene ring in (E)-1-(1H-pyrrol-2-yl)-3-(thiophen-2-yl)prop-2-en-1-one increased both the melting point and solubility of the sample compared with (E)-3-phenyl-1-(1H-pyrrol-2-yl)prop-2-en-1-one. This observation may be key for the future crystal engineering of heterocyclic chalcones for pharmaceutical applications.

Abstract:

In this paper, we describe the solvent-free three-component synthesis of 2,4,5-trisubstituted-1H-pyrrol-3-ol-type compounds from L-tryptophan. The first step of the synthetic methodology involved the esterification of L-tryptophan in excellent yields (93–98%). Equimolar mixtures of alkyl 2-aminoesters, 1,3-dicarbonyl compounds, and potassium hydroxide (0.1 eq.) were heated under solvent-free conditions. The title compounds were obtained in moderate to good yields (45%–81%). Density functional theory using “Becke, 3-parameter, Lee–Yang–Parr” correlational functional (DFT-B3LYP) calculations were performed to understand the molecular stability of the synthesized compounds and the tautomeric equilibrium from 3H-pyrrol-3-one type intermediates to 1H-pyrrol-3-ol type aromatized rings.

The crystal structures offac-(acetonitrile-κN)(2-{[3,5-bis(4-methoxyphenyl)-2H-pyrrol-2-ylidene-κN1]amino}-3,5-bis(4-<!?tlsb=0.2pt>methoxyphenyl)-1H-pyrrol-1-ido-κN1)tricarbonylrhenium(I)–hexane–acetonitrile (2/1/2), [Re(C36H30N3O4)(CH3CN)(CO)3]·0.5C6H14·CH3CN, (2), andfac-(2-{[3,5-bis(4-methoxyphenyl)-2H-pyrrol-2-ylidene-κN1]amino}-3,5-bis(4-methoxyphenyl)-1H-pyrrol-1-ido-κN1)tricarbonyl(dimethyl sulfoxide-κO)rhenium(I), [Re(C36H30N3O4)(C2H6OS)(CO)3], (3), at 150 K are reported. Both complexes display a distorted octahedral geometry, with afac-Re(CO)3arrangement and one azadipyrromethene (ADPM) chelating ligand in the equatorial position. One solvent molecule completes the coordination sphere of the ReIcentre in the remaining axial position. The ADPM ligand shows high flexibility upon coordination, while retaining its π-delocalized nature. Bond length and angle analyses indicate that the differences in the geometry around the ReIcentre in (2) and (3), and those found in three reportedfac-Re(CO)3–ADPM complexes, are dictated mainly by steric factors and crystal packing. Both structures display intramolecular C—H...N hydrogen bonding. Intermolecular interactions of the Csp2—H...π and Csp2—H...O(carbonyl) types link the discrete monomers into extended chains.

Abstract:

This article examines two groups of motifs in Roman visual culture: females modelled on kalathiskos dancers, and males modelled on pyrrhic dancers. Eclecticism is emphasized as a strategy which was used to introduce novelties that were appropriate within a Roman cultural context. The figures representing kalathiskos dancers and pyrrhic dancers were both changed in an eclectic manner and this resulted in motifs representing the goddess Victoria, and the curetes respectively. Kalathiskos dancers and eclectic Victoriae occur on many different media at least from the Augustan era and into the 2nd century AD. It is argued here that the establishment of these two motifs in Roman visual culture is closely related to the aesthetics which came to the fore during the reign of Augustus. Thereafter, both kalathiskos dancers and eclectic Victoriae lingered on in the Roman cultural context until many of the material categories on which they were depicted ceased to be produced. Unlike the kalathiskos dancers, the male figures modelled on pyrrhic dancers are so rare within Roman visual culture that we can only assume they were, to some extent, perceived as an inappropriate motif. This can most likely be explained by the negative attitude, amongst the Roman elite, towards male dancing.

Abstract:

Substituted 5-methylene-1H-pyrrol-2(5H)-ones underwent a 1,3-dipolar cycloaddition reaction with nitrile oxides to give the corresponding spiro heterocycles. Critical to this reaction was the development of a biphasic system for base-induced dehydrohalogenation of hydroximoyl chlorides, to give nitrile oxides, in the presence of a base-sensitive dipolarophile. A substituted N-tolyl 5-methylene-1H-pyrrol-2(5H)-one exhibited atropisomerism, which in turn led to a 4:1 facial selectivity during cycloaddition.
