The use of simile or analogy is frequently adopted by mathematicians in their attempt to explain features of mathematical knowledge to the general public. For example, mathematics looks like a tree or mathematics can be tour-guided by a scenic map. These, among others, are favorite descriptions appearing in popular mathematics writing. However, a comparison of mathematics with narrative, as suggested in the paper under review, is more to the point if one wants to explore in depth the status of mathematical knowledge. Indeed, Thomas's argument reminds us that the story of mathematics can be told in an axiomatic manner. As such, the very axiomatic-deductive aspect of the knowledge may be boring and tedious on an abstract level. This may well explain why mathematics is not attractive to nonspecialists. If ``proof and narrative are different ways of working out the consequences of relational hypotheses'', then various mathematical structures as ``stories engage the attention and fire the imagination of a reader''. In short, what Thomas says as a storyteller about mathematics and narrative is attractive and illuminating, especially to those teachers who like to explain to their students, math majors or not, what mathematics is.
