To carry out this commission, he set up a large workshop in which many artists trained, including Donatello, Masolino, Michelozzo, Uccello, and Antonio Pollaiuolo. When his first set of twenty-eight panels was complete, Ghiberti was commissioned to produce a second set for another doorway in the church, this time with scenes from the Old Testament, as originally intended for his first set. Instead of twenty-eight scenes, he produced ten rectangular scenes in a completely different style. These were more naturalistic, with perspective and a greater idealization of the subject. Dubbed "The Gates of Paradise" by Michelangelo, this second set remains a major monument of the age of Renaissance humanism.
