Alfonso X

Alfonso X

Anecdote...

The most celebrated of the works undertaken under Alfonso’s sponsorship was the compilation of the “Alfonsine Tables,” which were published on the day of his accession to the throne and remained the most authoritative planetary tables in existence for the following three centuries. The preparation of the tables was very laborious and was based, of course, upon the Ptolemaic scheme of the universe. Alfonso remarked that if God had consulted him during the six days of creation, he would have recommended a less complicated design.

Biographical Note: 

Alfonso X was King of Castile and León (1252–84), known as Alfonso el Sabio (Alfonso the Wise). He is particularly famous for his patronage of the arts and sciences, his revision of the Castilian legal code, and his encouragement of translations of Arabic works.
