Explaining the Epigraphic Habit in the Roman Empire: The Evidence of Epitaphs

It is now notorious that the production of inscriptions in the Roman Empire was not constant over time, but rose over the first and second centuries A.D. and fell in the third. Ramsay MacMullen pointed this out more than five years ago, with conclusions more cautionary than explanatory: ‘history is not being written in the right way’, he said, for historians have deduced Romes decline from evidence that–since it appears only epigraphically–has merely disappeared for its own reasons, or have sought general explanations of decline in theories political, economic, or even demographic in nature, none of which can, in turn, explain the disappearance of epigraphy itself. Why this epigraphic habit rose and fell MacMullen left open to question, although he did postulate control by a ‘sense of audience’. The purpose of this paper is to propose that this ‘sense of audience’ was not generalized or generic, but depended on a belief in the value of romanization, of which (as noted but not explained by MacMullens article) the epigraphic habit is also a rough indicator. Epitaphs constitute the bulk of all provincial inscriptions and in form and number are (generally speaking) the consequence of a provincial imitation of characteristically Roman practices, an imitation that depended on the belief that Roman legal status and style were important, and that may indeed have ultimately depended, at least in North Africa, on the acquisition or prior possession of that status. Such status-based motivations for erecting an epitaph help to explain not only the chronological distribution of epitaphs but also the differences in the type and distribution of epitaphs in the western and eastern halves of the empire. They will be used here moreover to suggest an explanation for the epigraphic habit as a whole.

Differences in chemo‐ and cytoarchitectural features within pars principalis of the rat anterior olfactory nucleus suggest functional specialization

The anterior olfactory nucleus (AON) lies between the olfactory bulb and piriform cortex and is the first bilaterally innervated structure in the olfactory system. It is typically divided into two subregions: pars externa and pars principalis. We examined the cytoarchitecture of pars principalis, the largest cellular area of the region, to determine whether it is homogeneously organized. Quantitative Nissl studies indicated that large cells (cell body area >2 standard deviations (SD) larger than the mean cell size) are densest in lateral and dorsolateral regions, while small cells (>1 SD smaller than the mean) are more numerous in medial and ventral areas. Further evidence for regional differences in the organization of the AON were obtained with immunohistochemistry for calbindin (CALB), parvalbumin (PARV), glutamic acid decarboxylase (GAD), and choline transporter (CHT). Cells immunopositive for CALB (CALB+) were denser in the deep portion of Layer II, although homogeneously dispersed throughout the circumference of the AON. PARV+ cells were located in the superficial half of Layer II and were sparse in ventral and medial regions. CHT+ and GAD+ fibers were denser in lateral versus medial regions. No regional differences were found in GAD+ somata, or in norepinephrine transporter or serotonin transporter immunoreactivity. The observed regional differences in cyto‐ and chemoarchitectural features may reflect functional heterogeneity within the AON. J. Comp. Neurol. 498:786–795, 2006.

Spatial distribution of neural activity in the anterior olfactory nucleus evoked by odor and electrical stimulation

Several lines of evidence indicate that complex odorant stimuli are parsed into separate data streams in the glomeruli of the olfactory bulb, yielding a combinatorial “odotopic map.” However, this pattern does not appear to be maintained in the piriform cortex, where stimuli appear to be coded in a distributed fashion. The anterior olfactory nucleus (AON) is intermediate and reciprocally interconnected between these two structures, and also provides a route for the interhemispheric transfer of olfactory information. The present study examined potential coding strategies used by the AON. Rats were exposed to either caproic acid, butyric acid, limonene, or purified air and the spatial distribution of Fos‐immunolabeled cells was quantified. The two major subregions of the AON exhibited different results. Distinct odor‐specific spatial patterns of activity were observed in pars externa, suggesting that it employs a topographic strategy for odor representation similar to the olfactory bulb. A spatially distributed pattern that did not appear to depend on odor identity was observed in pars principalis, suggesting that it employs a distributed representation of odors more similar to that seen in the piriform cortex.
