The three saints in the panels are carrying a book or pointing to a scroll, the meaning of which I am unsure. They also have halos around their head apparently indicating ascended beings. These tempra paintings are worthy in the sense of warmth and aspiration. Giotto is likely hiding important elements in these paintings that impart hidden truths as well. Each would likely take some time to properly interpret. (;>))
Maybe you're right)
I don't know rica but it's interesting to think about. I suppose Giotto had his intentions and reasons. With the secret knowledge and secret societies it's always possible that there is more in the paintings. It's just nice to reflect on things from time to time. (;>))
