“I see that you are beginning to compose latin themes, but not without bad mistakes. Learn something every day. Exercise your memory diligently. If Terence is one of the books you read at school, I desire that you will commit it to memory from beginning to end. No one will ever speak latin well who has not thumbed Terence.”
-Isaac Casaubon in a letter to his son Meric, quoted/translated in Mark Pattison, Isaac Casaubon (Oxford: Clarendon Press 1892) p.229
