The development of a scientific understanding of synesthesia from early case studies (1849-1873)

The first case of synesthesia was reported in 1812 ( Jewanski, Day, & Ward, 2009 ). However, it took almost seven decades before the idea of synesthesia entered the mainstream of science and, subsequently, art. There are no known new cases described between 1812 and 1848, but in the following three decades there are at least 11 reported cases of synesthesia and many reviews of these cases. This comes at an important period in the history of the neurosciences, and for sensory physiology in particular. However, the literature that describes synesthesia during this period is largely unknown to contemporary researchers and historians. The aim of this review is to discuss the reports of synesthesia during this period, providing translations of some key passages, and to place these reports within the contextual framework of nineteenth-century neuroscience.     

An ongoing Austronesian expansion in Island Southeast Asia

The Austronesian expansion into Island Southeast Asia and the Pacific was the last and most far-reaching prehistoric human migration. Austronesian languages replaced indigenous languages over nearly half the globe, yet the absolute number of Austronesian colonists was small. Recently, geneticists have identified large geographic disparities in the relative proportions of Asian ancestry across different genetic systems (NRY, mitochondrial DNA, autosomes and X chromosomes) in Austronesian-speaking societies of Island Southeast Asia and the Pacific. Surprisingly, a substantial genetic discontinuity occurs in the middle of a continuous chain of islands that form the southern arc of the Indonesian archipelago, near the geographic center of the Austronesian world. In the absence of geographic barriers to migration, this genetic boundary and swathe of Austronesian language replacement must have emerged from social behavior. Drawing on decades of comparative ethnological research inspired by F.A.E. van Wouden’s structural model of Austronesian social organization, later codified by Claude Lévi-Strauss as “House societies” (“sociétés à maison”), we propose a two-stage ethnographic model in which the appearance of matrilocal “House societies” during the initial phase of the Austronesian expansion, and the subsequent disappearance of “House societies” in lowland rice-growing regions, accounts for the observed linguistic, genetic and cultural patterns.     

The Master and Marguerite: Godfrey of Fontaines' praise of The Mirror of Simple Souls*

This article examines the evidence for the intellectual and practical relationship between Marguerite Porete and the secular master of theology Godfrey of Fontaines. It analyses the nature, timing, and importance of Godfrey's response to The Mirror of Simple Souls, and argues that considering the interaction between these two figures has important consequences for our understanding of both of their careers.
