However, Petrarch did use number symbolism, and was very much influenced by Augustine's use of such (of which we have already given an example in the division of the City of God (one of the books it is said for Petrarch to possess) into 22 books) :

Petrarca had two books, he couldn't have arranged a 3rd for the short introduction (in the case, it was in his intention the first chapter of book Nr. 1, which governs this part), or for a combining chapter in the middle of the book (in this case it would be chapter 122, book 1) . Here are the titles:
Book 1, chapter 1 : De aetate florida
Book 1, chapter 122: De spe vita aeternae
Both titles might fulfill the "specific function", it eben might be thought, that 1 plus 122 are regarded by the author as one chapter (begin and end of book 1 - book 1 is the better part of life).
Interesting is the feature, that spes enters as speaker after chapter 108, having 14 chapters still to do ... the negative book 2 ends with the meta chapter death, and this meta chapter also has 14 chapters.
Your information about Augustine is interesting ... as I take from the decription at ...
http://www.newadvent.org/fathers/1201.htm
.., Augustine had in chapter Nr. 13 a reference to death (as it is also Tarot):
Some other chapters might be also "somehow Tarot-related" ... he seems to have a basic partition 1-10 and 11-22 (book1 and book 2), and the web page tells in chapter 11 the mystery of it with ..Book 13 In this book it is taught that death is penal, and had its origin in Adam's sin.
... looking through the further description, we find in chapter 20 ...Here begins the second part of this work, which treats of the origin, history, and destinies of the two cities, the earthly and the heavenly. In the first place, Augustine shows in this book how the two cities were formed originally, by the separation of the good and bad angels; and takes occasion to treat of the creation of the world, as it is described in Holy Scripture in the beginning of the book of Genesis.
Book 20 Concerning the last judgment, and the declarations regarding it in the old and new testaments. [Last judgment, as in Tarot]
... in 21 the city of the devil ...
.. and in 22 the city of godBook 21 Of the end reserved for the city of the devil, namely, the eternal punishment of the damned; and of the arguments which unbelief brings against it.
So maybe it's a chapter ordering like ...Book 22 This book treats of the end of the city of God, that is to say, of the eternal happiness of the saints; the faith of the resurrection of the body is established and explained; and the work concludes by showing how the saints, clothed in immortal and spiritual bodies, shall be employed.
1-10 (...)
11-20 about the both cities
21 about the city of devil
22 about the city of god
... whereby the explanation of the web page indicates this sorting:
1-10 (...)Book 15 Having treated in the four preceding books of the origin of the two cities, the earthly and the heavenly, Augustine explains their growth and progress in the four books which follow; and, in order to do so, he explains the chief passages of the sacred history which bear upon this subject. In this fifteenth book he opens this part of his work by explaining the events recorded in Genesis from the time of Cain and Abel to the deluge.
11-14 (... origin of cities)
(15 ... sacred history)
16-19 (... )
20 Last judgment
21 city of devil
22 city of god.
It's not obvious to me, which structure the first 10 are following.
