The Letters of Cicero are thoroughly natural - colloquia absentium amicorum, to use his own phrase.
And his popular works, the Adagia, and the Colloquia (1524), had established themselves as standard books in the more easy going age, when power, secure in its unchallenged strength, could afford to laugh with the laughers at itself.
For the same purpose his Colloquia may be consulted.
These have included regular work-in-progress seminars, weekly post-graduate seminars, and over twenty colloquia and symposia.
Archbishop Trench (Study of Words) supposed that when " religion " became equivalent to the monastic life, and " religious " to a monk, the words lost their original meaning, but the Ancren Riwle, ante 1225, and the Cursor Mundi use the words both in the general and the more particular sense (see quotations in the New English Dictionary), and both meanings can be found in the Imitatio Christi and in Erasmus's Colloquia.
