The first 50 dialogues of Corderius' colloquia are now on Latinum.
These have been formulated for students, so each line of dialogue is given alternately in Latin, then English, then again in Latin.
This lets the student listen, check their understanding immediately, then listen again to pick up new vocabulary/grammar.
100 dialogues will be recorded from this author, giving a useful resource.
Corderius was a standard textbook from 1564, until the late 1700's in grammar schools across protestant Europe. Much idiomatic Latin can be learned from his dialogues.
