Art History questions about Giotto article history homework help

I am having trouble with these three questions for my Art History class. I have an article to help answer them as well and I will attach it. The answers have to be 125 minimum for each answer. These are the questions.

1. This article discusses Giotto’s use of illusion and “things not seen” to support the religious narrative in his paintings. Explain how the 15th century writer Cennino Cenninidefines the art of painting and the crucial use of illusion in painting.

2. Discuss the importance of Giotto’s “Joachim Among the Shepherds,” [Fig. 4] as an example of his “skill in manipulating the devices of pictorial illusion…to suggest realities beyond the threshhold of representation….”

3. What does the word ingegno mean? How may it be applied to Giotto, and perhaps his painting “Kiss of Judas,” [Fig. 7]?

I will attach two documents one containing the article to help with the questions and another is an abstract about them as well. If you have any questions please ask me, don’t worry about the font style or size. And if you use any outside sources please cite them as well.

Thank you in advance.
