Terence was a playwright of the Roman Republic. His comedies were performed for the first time around 170–160 BC. Luther frequently quoted from Terence's works and especially commended his comedies to children being taught in the schools. Terence also had a great influence on William Shakespeare. Here are some words of wisdom from Terence -- not necessarily quoted in Luther.
"Their silence is sufficient praise."
"There is a demand in these days for men who can make wrong appear right."
"There is nothing so easy but that it becomes difficult when you do it reluctantly."
"Too much liberty corrupts us all."
"What is done let us leave alone."
"Charity begins at home."
"Moderation in all things."
"I have everything, yet have nothing; and although I possess nothing, still of nothing am I in want." [cf. 2 Cor. 6:10]
