The trained archaeologist and present director of the Swiss Museum of Games has already published numerous articles in books and specialist journals, particularly in Board Game Studies (Yearbooks of the International Society for Board Game Studies) whose co-editor he is. His beautifully designed book Globusspiel und Himmelsschach - Brett- und Würfelspiele im Mittelalter was published only in a limited edition (Wissenschaftliche Buchgesellschaft, Darmstadt 1998. 64 pp. / Hardback, incl. mostly coloured illustrations.)
From the blurb (translated by R.B.): "In many respects the Middle Ages were an epoch full of the joys of life, an age of artistic creativity and innovation, an age of erudition but especially a playful age. Games served as a metaphor for the relations of man to the Creation, were the subjects of erudite discourses, educational instrument or more or less refined leisure activities – these aspects provide a backdrop for the medieval culture of play."
