"The just are two, and are not understood there"

(Canto 6, line 73)

Dante does not specify who these two "just" people are. It might be that "two" is an unspecific number here, used to convey how few the just are. Some people believe it refers to Dante himself and the historian Compagni, or Dante and the poet Guido Cavalcanti. Sapegno says of the idea that Dante includes himself among these "two" here that it certainly would be outrageous, but far from impossible. Modern commentator Mazzoni proposes, after his reading of St. Thomas' Aristoteles commentary, that these "two" are not people, but two modes of "justness", one natural, unwritten justice, and one specified in law, none of which were obeyed in Florence.
