A second phase of Charles V's program for Granada began in 1526. An ambitious plan was developed to make Granada the centre of an empire; Gothic was rejected in favour of a new vocabulary based on Greco-Roman antiquity. This was the justification for abandoning Enrique Egas's Gothic-style plan for Granada Cathedral and adopting a Renaissance-style one (1528) by Diego de Siloé: the cathedral's new imperial status required a style recalling that of Imperial Rome. After Siloé's death (1563) Juan de Maeda ( fl 1563-1582) continued the work.
