The current volume comprises eighteen chapters dealing in depth with Martin Codax's work and the Vindel Parchment from five basic perspectives: literature, linguistics, codicology and ecdotics, music and history.

The medieval Castilian King Alfonso X «the Learned» (ruled 1252 - 1284) and his grandson, King Dinis of Portugal (ruled 1279 - 1325), not only were the two most prolific poets of the Galician-Portuguese Cancioneiros but also figured prominently as patrons of culture and the arts. This book examines the influence of Alfonso X and his court on Dinis in the fields of translation, law, higher learning, historiography, and poetry.
