It is just conceivable that the Viceroy would have thought it impolitic to attribute his sudden cure to a native remedy rather than to the Mass and the alms. Was it, in fact, a native remedy, or was it discovered by the Jesuits? The evidence is ...”

Increasingly large societies of unrelated individuals who are entirely unknown to one another are now held together not only by innate predispositions to co-operation, channelled by imitation and learning into different cultural forms, but also by social institutions that give small numbers of individuals power to control the ...”

Leo’s dying father bequeaths him a potsherd on which is written in Greek a family history showing that Leo is descended from the royal house of pharaohs, and an instruction that he seek out a beautiful white sorceress ...”

Maybe even the famous Unknown Shooter who – according to the conspiracy theorists – had been lurking on the grassy knoll near Dealey Plaza when Kennedy’s motorcade approached? I told myself that was crazy, but it was impossible to know for sure. Worse still is the sight of de ...”

Not only do we not know what the general political-economic climate will be four years from now, we do not know in particular where the Lib Dems will ...”

He retired from league football in 1994, and his name, ‘for reasons that remain unknown’, was informally adopted and shared by hundreds of artists and social activists all over Europe … In Italy, between 1994 and 1999, the so-called Luther Blissett Project (an organised network within the open community sharing the ‘Luther ...”

The folktale doesn’t survive from primeval times but is a living, continuously adapting historical artefact. In 18th-century Russia, the struggle against the Old Believers, who ...”

As a kind of confraternity that straddles the ages and the globe, such merchants can be castigated as greedy or lionised as adventurers. By virtue of their cross-pollination of cultures ...”
