* Metalworking: He learned skills in working with gold, silver, and other metals, developing his hand-eye coordination, precision, and problem-solving abilities.
* Design and Modeling: Creating intricate metalwork required strong design skills and the ability to translate designs into three-dimensional objects.
* Mathematics and Geometry: Necessary for precise measurements and calculations in his craft.
* Engineering Principles: Although not explicitly taught in the guild, his work inherently involved understanding principles of structural stability and mechanics.
While he lacked a classical liberal arts education, his guild training and his innate talents provided a solid base for his later groundbreaking achievements in architecture and engineering. He was largely self-taught in the field of architecture, drawing on his knowledge from other fields and through observation and experimentation.
