from book IX, chapter 6
quantum flevi in hymnis et canticis tuis, suave sonantis ecclesiae tuae vocibus conmotus acriter! voces illae influebant auribus meis, et eliquabatur veritas in cor meum, et exaestuabat inde affectus pietatis, et currebant lacrimae, et bene mihi erat cum eis.
How abundantly did I weep to hear those hymns and canticles of thine, being touched to the very quick by the voices of thy sweet church song! Those voices flowed into mine ears, and thy truth pleasingly distilled into my heart, which caused the affections of my devotion to overflow, and my tears to run over, and happy did I find myself therein.
from book X, chapter 20
res ipsa nec graeca nec latina est.
The thing itself is neither Greek nor Latin.
