|Depiction of the eventual Pope and son|
The story begins with a father whose son has been away studying at school for the past ten years, when he received a letter from the son's teacher claiming that he needed to take his son back as he could not teach him any more. Upon the son's return, his father set up a large feast to celebrate him even inviting many different powerful noble men from all across Italy. The noble men all gave speeches like in most ancient feasts, but once they were done on of them asked the son to tell him one thing that he had learned in his ten years of schooling. The son claimed to have learned the language of various animals including: dogs, frogs, and even birds. The whole crowd erupted in laughter at the answer and all left almost immediately. The father was mocked for being so proud while the son was made fun of for being a fool. The father became so enraged at this that he ordered two of his servants to go out and kill the son. After they did this they were supposed to bring back his heart, but they could not do it and instead decided to bring back a random dog's heart instead. After this the boy flees for a long time until he came across a rich treasurer's castle and asked to stay inside as he had been on the move for some time. Upon his arrival though a group of dogs came to gather outside the castle and as the son understood them he found out that a large group of assassins were coming to attack the castle that very night. The treasurer set up the guards to eliminate the assassins and was so grateful to the son that he offered his daughter's hand in marriage to him on the condition that he couldn't come back until a year and three days had passed. Next, the boy met the king's daughter and was able to help her finally sleep by calming the frogs in the nearby pond as she had thrown a cross into the fountain, so after removing she was saved and also offered to the son in marriage. The son finally left and went to Rome where he made three new friends along the road only to be followed by a flock of singing birds. The son finally interpreted what they were saying as they were trying to pick the new Pope and suddenly it landed on the son who shortly after became Pope. The newly-ordained Pope summoned all the people he had helped as well as his father, who instantly wept as he realized he was wrong, and they lived together in peace.
