Having provided an academic and historical context, the Alphonsine Tables are studied, this being the project on which both authors collaborated for over a decade. Undoubtedly, the Alphonsine Tables are the most influential scientific production that came out of Alfonso X the Wise's Court due to its diffusion throughout Europe. Afterwards, the text provides an analysis of each author's work, independently, by studying one of each ones' production.
