In the Roman world, lamps with replicated images of sex were in circulation from the late 1st c. BCE until the end of the 4th c. CE. This paper maps out key regional and chronological trends in the representation and consumption of these objects using data from 11 provincial sites. It demonstrates sustained sensitivity of replicated sexual disc-reliefs to distinctive regional styles of consumption and representation. It also shows that symplegmata disc-reliefs were interacting and changing over time, resulting in innovative imagery that produced new meanings in localized contexts. This is the first comparative systematic study of the styles of consumption and representation of replicated lamp iconography using statistical methods. As such, the paper contributes a novel methodological approach to Roman sexuality research and also advances our understanding of how Roman replicated sexual imagery came about, how it constructed meaning, and how it was consumed by different communities over time.

This article illustrates the use of an empirical method for examining the perceptual identification of gayness in male speakers. It demonstrates how, by digitally manipulating the speech of isolated individuals, it is possible to obtain reliable evidence that pitch range and sibilant duration may act as indexical of a gay male identity. Further scrutiny of this result, however, illustrates that linguistic indexicality is not as straightforward as it originally appears. Subsequent analyses of the data highlight the ways in which the perceptual evaluation of sexuality is a highly contingent process, dependent upon a variety of sociolinguistic factors. An envelope of variation in listeners' affective judgments of a speaker is shown to exist, and it is argued that research on the perception of identity must go beyond identification of salient features, and also consider when and why these features are not salient.I greatly benefited from the insight and assistance of the following people, whom I would like to thank: Renée Blake, Lisa Davidson, Penny Eckert, Rudi Gaudio, Ron Butters, Keith Walters, Barbara Johnstone, and three anonymous reviewers.
