The E3GLOBAL project proposes to write the first global history of the 1919 total solar eclipse — perhaps the most famous solar eclipse ever. This eclipse was exceptional for a variety of scientific, political, social, and even religious reasons and from its observation the most spectacular of Einstein’s general relativity theory predictions was confirmed, the bending of light passing through a gravitation field.

The project shifts the focus from Einstein and the effects of British travels to the travels per se, analysing them jointly in a comparative and interrelated way, with as much detail as possible, while giving prominence to a myriad of participants, professionals and lay people, known and unknown, in the convoluted process that let to the observation of totality, both in Sobral as well as in Príncipe.
