Choreographer Marie Sallé's Pigmalion of 1735 has long been recognised as one of the most seminal dance works of the period. Yet no choreography survives. This article draws on written, musical, and iconographical evidence of the period to illuminate this previously inaccessible production.

The better models of e-Gov posit high levels of informational communication between citizen and state. Unfortunately, in one area, that communication has traditionally been poor: that is, access to sources of law. There have been a number of reasons for this, but a primary one has been that law was historically mediated for the citizen by the legal profession. This situation is changing with ever increasing numbers of unrepresented litigants being involved at all levels of national court systems in each and every country as well as a generally higher level of intrusion of legislation into everyday home and business life. There have been attempts to improve access through internet based services, but these have improved communication (‘understanding of law’) to only a limited extent. It may be time, this article suggests, to consider re-engineering legal sources so that they better fit the needs of eGov.

This paper examines the marginal place of ‘medieval geography’ in contemporary geographical scholarship. Over the past two decades, geographers' studies of the subject’s historiography have tended to focus mainly on ‘modern’ and ‘early-modern’ rather than medieval geographies. This contrasts with the early 20th century when ‘medieval geography’ was seen by geographers to be part of the discipline’s long history. Set within the context of current discussion on writing geography’s histories, the paper examines how geographers, and latterly historians, have sought to characterize and represent medieval geographies. This reveals that the subject of geography in the Middle Ages shared in the same fluidities and ambivalences that characterize geography today. The paper thus helps to challenge orthodox views of geography’s history, and argues that the connections and continuities that have shaped geography for over two millennia cautions us against taking a compartmentalized approach to historiographies of geography.

Ambisonics and higher order ambisonics (HOA) technologies aim at reproducing sound field either synthesised or previously recorded with dedicated microphones. Based on a spherical harmonic decomposition, the sound field is more precisely described when higher-order components are used. The presented study evaluated the perceptual and objective localisation accuracy of the sound field encoded with four microphones of order one to four and decoded over a ring of loudspeakers. A perceptual test showed an improvement of the localisation with higher order ambisonic microphones. Reproduced localisation indices were estimated for the four microphones and the respective synthetic systems of order one to four. The perceptual and objective analysis revealed the same conclusions. The localisation accuracy depends on the ambisonic order as well as the source incidence. Furthermore, impairments linked to the microphones were highlighted.
