The spring,the seed and the tree: Gregory of Tours on the wonders of nature

In the preface to his liturgical calendar The reckoning of the course of the stars Bishop Gregory of Tours (538–594) — author also of Ten books of histories and Eight books of miracles as well as of a Commentary on the understanding of the Psalter (of which, however, only fragments are preserved) — declares God's “wonders” of the natural world to be superior to the seven ancient wonders of the world. The reason for this is that the latter, being works of men, are subject to decay and destruction, while the former, as miraculous works of God, are divinely sustained and renewed daily or annually, thereby becoming imperishable. An examination of the associative contexts in which two of these wonders — the sea (enlarged to include water in its various forms) and plant life — occur in the rest of Gregory's works reveals several essential themes of his thinking not only about nature, but also about God, man and society. Thought, for him, nature as a (divinely sustained) system of regularities does exist as a kind of backdrop, sudden unpredictable divine — and sometimes diabolic — action in and through phenomena occupies the center of the stage. Gregory tends to see this action in the shape of what he regards as pre-existing images or patterns of invisible spiritual truth, to which the visible, even material, structure of events must necessarily conform. He shows, too, how this action could reflect as well as meet various needs of the individual and of society as a whole. An association which recurs almost constantly in his treatment of divine action in these natural phenomena, which he sometimes describes as analogous to that in man, is precisely that with the cluster of closely related concepts of renewal, rebirth and creation ex nihilo. Together with what appears as an extreme, as it were ‘poetical’, sensitivity to sudden perceptions and intuitions, something like a longing for and surrender to what he describes as “astonished admiration” may have helped to make possible his recognition of that which he designated as divine creative power in the world of visible reality as well as in man's inner experience. His seeing this as an essential dynamic of the holy may mean that he felt it to be a fundamental need and concern not only of the individual personality but also, more obscurely, of the society in which he found himself.     

HETEROGENEOUS TASTES AND RESIDENTIAL LOCATION*

ABSTRACT. In a simple urban model, where the only spatial distinction made is between center and suburb, we introduce a uniform distribution of preferences for land. Under a logarithmic utility function, we examine how the location and consumption decisions of individuals differ in consequence of their different preferences for land. Comparative statics indicate that the qualitative response of the city at equilibrium to changes in per capita income and transportation cost is not affected by the introduction of such heterogeneity. Possible extensions are also briefly discussed.     

Mapping population data from zone centroid locations

The author describes the difficulties associated with the use of maps to represent census data. "A review of the problems associated with population mapping is followed by a discussion of [an alternative method known as] a raster method for handling census data, based on population-weighted centroids, and its implications for GIS "[geographic information systems]." The geographical scope is worldwide, with an example provided using data for Wales.     

SPATIAL EQUILIBRIUM WITH FOOTLOOSE FIRMS*

ABSTRACT. We determine the location equilibria in a duopoly model under a novel solution concept. Typically, spatial equilibrium is described as either a simultaneous price and location game, or else as a two-stage location-then-price game. We introduce a new alternative, a two-stage price-then-location game. It is well known that no (pure strategy) equilibrium usually exists under the two standard solution concepts when products are homogeneous. We show this is also true for the new concept. We then provide numerical results for a specific functional form (the logit model) which introduces product heterogeneity into the standard framework, restoring equilibrium when the degree of substitutability between products is not too small.     

The Ngovo Group: an industry with polished stone tools and pottery in Lower Zaïre

Summary Now, for the first time, it is possible to place in an exact archaeological context the polished tools which have been collected for many years on the surface in the savanna immediately to the south of the equatorial forest. In Lower Zaïre, in an area of 6000 km², polished tools have been found systematically associated with a particular type of pottery. This pottery, which was previously known as Groupvi pottery and which we propose calling Ngovo group pottery is very distinctive.Although faunal remains associated in one case were of wild animals, someElaeïs andCanarium nuts could indicate the beginnings of agriculture. A series of dates in good agreement place these polished tools and this pottery within the last two centuries bc.At the present time, iron-working in Lower Zaïre has not been dated prior to the second century ad. This Early Iron Age is associated with the Kay Ladio group pottery which is possibly derived from the Ngovo group.

Résumé Pour la première fois, il est possible de préciser le contexte archéologique des outils polis que depuis longtemps on recueillait en surface dans les savanes immédiatement au sud de la forêt équatoriale.Au Bas-Zaïre, dans une zone de plus de 6000 km², des outils polis ont été trouvés systématiquement en association avec une céramique d'un type particulier. Cette céramique, connue précédemment sous le nom de céramique du groupevi et que l'on propose d'appeler dorénavant groupe de Ngovo, est très caractéristique.Bien que les restes de faune qui y sont associés dans une grotte soient ceux d'animaux sauvages, des noix d'Elaeïs et deCanarium indiquent peut-être un début d'agriculture.Une série de datations remarquablement convergentes placent ces outils polis et cette céramique durant les deux derniers siècles bc.La métallurgie n'est jusqu'à présent pas datée au Bas-Zaïre avant le 2e siècle ad. Cet âge du fer ancien est associé à la céramique du groupe Kay Ladio qui dérive peut-être du groupe de Ngovo.

     

GAS LIQUID CHROMATOGRAPHIC ANALYSIS OF FATTY ACIDS IN FOOD RESIDUES FROM CERAMICS FOUND IN THE SOUTHWESTERN CAPE,SOUTH AFRICA

Gas liquid chromatography was used to analyse residues adhering to the inside of excavated potsherds from dated South African sites. The results suggested marine animal fat, possibly seal, had been cooked in the vessels. Fat of modern seals was baked and also analysed as a control sample. This gave similar results. The importance of seals in the prehistoric diet of the Southwestern Cape is supported by a large number of seal bones in the associated faunal material.
