Cyclopean horizontal, and the Cyclopean polygonal, architecture of the thirteenth century. And as Hubert of Lucca was the master of the new buildings at Florence, I have chosen the Cyclopean horizontal from his native city of Lucca; and as our Nicholas and John brought their new Gothic style into practice at Orvieto, I have chosen the Cyclopean polygonal from their adopted city of Orvieto.
