Eric Hobsbawm's long journey through history shows clear signs of a particular inner consistency. Since the beginning of the fifties until his last papers of 2011, Hobsbawm has ridden, as a main character, the long vicissitude of half century of historiography. A very long time, a time in which there were lots of epistemological changes, which seemingly led to deep divisions. In this essay we study the analytical tools Hobsbawm used. We point out the reasons why those tools manage to keep an high value of knowledge, regardless of any historiographical trend.
