Okay, so it looks like VS13 does NOT have a red capital letter starting it and comes right after VS12 in the manuscript. In fact the 2nd half of VS13 DOES have a red capital starting it!
VS13 = PD27 and PD27 typically runs:
ὧν ἡ σοφία παρασκευάζεται εἰς τὴν τοῦ ὅλου βίου μακαριότητα πολὺ μέγιστόν ἐστιν ἡ τῆς φιλίας κτῆσις.
VS13 in the Vatican manuscript reads:
https://digi.vatlib.it/view/MSS_Vat.gr.1950.pt.2/0255
So, the text in the manuscript reads:
ὧν ἡ σοφία παρασκευάζεται εἰς τὴν τοῦ ὅλου βίου μακαριότητα
Πολὺ μέγιστόν ἐστιν ἡ τῆς ?????? κτῆσις.
which means it breaks the sense of the saying as:
Of all the things that wisdom provides for the complete happiness of one's entire life
By far the greatest is the possession of ????... It looks like σοφιδο (or some version of σοφια????).
Are we to see these as two different sayings?? Something like:
Of all things, wisdom (sophia) provides for the complete happiness of one's entire life.
By far the greatest (thing) is the possession of wisdom.
This is curious and deserves some digging into.
And THIS is why I'm doing these one by one
