Note 1 — THE TRIALS OF GENIUS.
Reading edition
Arnolfo had proposed to raise the cupola immediately above the first cornice, from the model of the church in the chapel of the Spaniards, where the cupola is extremely small. Arnolfo was followed by Giotto in 1331. To Giotto succeeded Taddeo Gaddi, after whom, first Andrea Orgagna, next Lorenzo di Filippo, and lastly Brunelleschi were architects of the Cathedral.
