And this race was the Race of David, from which was born the glory and honour of the Human Race, that is to say, Mary.

And therefore it is written in Isaiah: "A virgin shall be born of the stem of Jesse, and a branch shall grow out of his roots." And Jesse was the father of the aforesaid David.

And it happened at one period of time that when David was born, Rome was born, that is to say, AEneas then came from Troy to Italy, which was the origin of the most noble Roman City, even as the written word bears witness.

Evident enough, therefore, is the Divine election of the Roman Empire by the birth of the Holy City, which was contemporaneous with the root of the race from which Mary sprang.
And incidentally it is to be mentioned that, since this Heaven began to revolve, it never was in a better disposition than when He descended from on high, He who had made it and who is its Ruler, even as again by virtue of their arts the Mathematicians may be able to discover.

The World never was nor ever will be so perfectly prepared as then, when it was governed by the voice of one man alone, Prince and Commander of the Roman people, even as Luke the Evangelist bears witness.
