  (former New Hebrides) exists a practice of drawing symmetrical figures on
  the ground\, according to ‘rules’ that constrain the practice and that al
 low us to study its ‘mathematical dimension’. Based on a survey carried ou
 t between 2016 and 2019 on Pentecost Island within the Raga society\, and 
 a re-reading of the Marcia Ascher’s ethnomathematical work\, I have develo
 ped a new mathematical model and IT-tools to highlight the operative and a
 lgorithmic nature of this practice. The ethnographic data led me to introd
 uce several concepts—cycles in graphs\, topological operations\, algorithm
 s—that seem to be at the very core of the processes of creation and memori
 zation of these drawings. These modeling tools allow us to study the pract
 ice of sand-drawing among the Raga societies\, not as an isolated fact\, b
 ut as a revelation of their way of ‘experiencing and inhabiting the world’
  as many anthropologists\, like Philippe Descola\, are now used to talk ab
 out ‘culture’. From Veblen’s theorem to the ontologies of the Raga\, this 
 talk will present a case of mathematical otherness that might be of intere
 st to historians of mathematics as well as philosophers of mathematics and
  anthropologists.\n\nWebsite: http://www.cs.mcgill.ca/~dirk/workshop\n
