The Etymological Method in Alphonsine Chronicle
The etymological method was an important tool for medieval historians. Their main source was Isidore of Seville’s Etymologiae sive origines, which outlined the principles and methods of how to derive etymologies. This tradition was taken up by many medieval authors, who used these principles in their historical writing. My thesis examines instances of etymologia in the General Estoria, written in the 13th century under Alfonso X of Castile. What is especially interesting is how the compilers adapted and revised etymologies they encountered in their predecessors' works, and whether the treatment of the sources varied based on the language of the source text.
