Relatively unknown in the English-speaking world, but widely admired in Europe and the Hispanic Americas, King Alfonso X is remarkable subject and, in Professor Simon Doubleday, has found an erudite and learned biographer. This is an excellent history of Alfonso the man, illuminated by the writer's comprehensive understanding of medieval Spain and its place in Europe. We meet the young Alfonso, precocious kinglet; the martial Alfonso, some of a warrior King, learning warfare, mounted, by his father's side, besieging the beautiful city of Ishbila (Seville); and the 'philosopher king' Alfonso, astronomer and ever curious intellectual, admirer of Islamic and European culture, ancient and modern. A practising poet, musician and writer, Alfonso has a claim to be history's first 'renaissance man' his story, from early years to a sad demise, resonates across the centuries.
