Magnetic properties of ancient coins

The almost ubiquitous presence of small amounts of iron in ancient coins gives them remanent magnetic properties which can be measured easily on commercial magnetometers. The stability of the remanence suggests that ancient coins might retain information about the geomagnetic field at the time and location of manufacture and so be valuable in setting up archaeomagnetic dating curves. However, measurements show that the remanence directions tend to be too scattered for this purpose, although it is quite possible to distinguish magnetically the obverse and reverse faces of struck coins.Saturation remanence studies of coins and coin analogues indicate that the main carrier of the remanence in struck coins is precipitated fine-grained iron (rather than the oxides of iron) which is produced during the minting process. The intensity of the remanence generated depends upon the thermo-mechanical history of the flan prior to striking, which suggests that the magnetic properties of such coins are not simply related to the provenance of the ores used.

Warts and the kings of Parthia: an ancient representation of hereditary Neurofibromatosis depicted in coins

Parthian coins depict a nodule on the face of many of their kings over succeeding generations. Loosely described as a wart in the literature, the nature of these lesions has been the subject of speculation. The accepted view is that they were unlikely to be simply a cosmetic or symbolic feature. Evidence suggests that they may represent the cutaneous tumors of Neurofibromatosis. The hereditary nature and physical appearance of these round nodules are consistent with this diagnosis. Although final proof may be lacking, these prominent facial features are worthy of discussion even though the matter may not be settled with certainty.     

Sir Charles Grandison,Natural Law and the Fictionalised English Gentleman

This article enquires into the relation between enlightened humanist conceptions of natural law and the period novel's fictionalization of the English gentleman in the context of its marriage plot. Marriage played a key role in enlightened theorisations of natural law precisely as an institution capable of grounding familial and civil life in an emerging concept of human nature. Yet public debate about the state's role in the regulation of marriage in mid-eighteenth-century England demonstrates that natural law lent itself to very different models of sovereignty and governance. The antinomies that characterized natural law's circulation in the English context are uniquely fictionalized in Samuel Richardson's last novel, Sir Charles Grandison (1753–54), a lengthy parallel narrative of failed courtship and matrimonial felicity that draws upon Pufendorf's model of natural law, yet is only partly implicated in its secular humanism. The novel's eponymous gentleman hero – a ‘Man of Religion and Virtue’ – exemplifies a mix of Anglican piety, civic virtue and disinterested sympathy that is sanctioned by natural law and sealed by the English marriage plot.     

从嫁妆制度的变化看古罗马社会妇女的经济地位

古罗马实行的是嫁妆婚姻."女儿出嫁给予嫁妆"从一种习俗变成法律的硬性规定;嫁妆的数额经历了由少到多的变化;妻子对嫁妆的权利则经历着从无到有的演变.这是一个逐渐对妇女有利的发展过程,也是罗马财产让渡的一个发展过程,它对于妇女而言不仅仅是获取陪嫁物,更重要的是通过嫁妆参与了社会财产的分配.罗马妇女通过嫁妆制度参与社会财产分配与让渡,在罗马社会发展进程中起到重要作用,从而显示出自己独特的经济地位.     

Anatomists and entrepreneurs in early eighteenth-century London

Anatomical demonstration in the eighteenth century took place in many formats. In this essay I discuss public anatomical demonstration as performed by entrepreneurial anatomists in London between 1700 and 1740. These anatomists offered courses, advertised in newspapers, to anyone who was willing to pay. In contrast to courses offered in official settings to prospective physicians and surgeons, these courses emphasized natural philosophy and natural theology rather than practical knowledge. Entrepreneurial lecturers also aimed to entertain. In this article I examine the lectures of James Douglas, William Cheselden, and Frank Nicholls, each of whom differed significantly from the others in style and content but were all anatomical entrepreneurs. All of them, moreover, employed not only human cadavers but also living and dead animals in their lessons. I examine the content of the lectures and the motivations of the lecturers' audiences. I also argue that the prevailing historiographical representation of eighteenth-century science as "polite" requires considerable revision to accommodate as impolite an activity as public anatomy.     

The history of the book and publishing in eighteenth-century Italy

Based on published and untapped sources, the article sets out to explore the cultural and material conditions of the book trade in Italy during the eighteenth century. Special concern is given to the import of French printed works and pamphlets as a means to diffuse the Enlightenment south of the Alps. The text does not address problems of authorial status, but provides a general assessment of the literary market and its impact on the reading habits of the elites. Critical and bibliographical information is also provided about the renewal of interest for the history of the book and reading in Italy since the 1980s.     

Assessment of material characteristics of ancient concretes,Grande Aula,Markets of Trajan,Rome

The Grande Aula, or Great Hall, of the Markets of Trajan (AD 96 to 115) is an intact example of the domed, concrete architecture of imperial Rome. Petrographic, x-ray diffraction, chemical, and SEM analyses demonstrate that wall mortars contain Pozzolane Rosse volcanic ash aggregate (harenae fossiciae) and strätlingite, a complex calcium aluminate cement hydrate (C₂ ASH₈) that gives modern cements good durability and compressive strength. Specific gravity tests and a new petrographic method for assessing bulk densities indicate unit weights of about 1750 kg/m³ for the wall mortars and 1430–1640 kg/m³ for the pumice bearing, vaulted ceiling mortars. Innovative point load source tests record the tensile strengths (f_t) of the aggregate and interfacial elements of the conglomeratic concrete fabric. These suggest f_t of about 2.7 MPa for brick, 1.2 MPa for Tufo Lionato tuff, and 0.9 MPa for Tufo Giallo della Via Tiberina tuff coarse aggregate (caementa), based on a tentative, approximate correlation with splitting (Brazilian) tests. The pozzolanic mortar and interfacial zones have lower f_t in the range of 0.8 MPa to 0.5 MPa. The relatively low mortar strength and its somewhat tenuous adhesion to the coarse aggregate suggests that the caementa may have arrested the propagation of tensile microcracks that formed in the mortar, thereby increasing the composite tensile strength of the concrete. Roman builders selected the complex aggregate mixes to optimize the performance of the wall and vault concretes.     

The Netherlands in the constellation of the eighteenth-century Western revolutions

In the constellation of the eighteenth-century revolutions, the French events have always occupied a dominant position. Consequently the other European upheavals have been considered as being provoked or strongly influenced by France. Yet, the Dutch revolutions in the 1780s and 1790s provide some important nuances to this interpretation. Before the French took over the Bastille, there was already a Dutch revolution with devoted Patriots, speaking about rights of man and constitutions. The Patriots had to flee abroad in 1787. In 1795, thanks to the French Army, they were able to return to their drawing boards, eager to think anew their government and society. This paper investigates how they did it and whether the American and French precedents were so influential after all in the construction of the Batavian Republic.
