Laudator Temporis Acti

Apropos of grammars and syntaxes Krueger's Greek Grammar is a mirror of his life. The quarrel with his wife, his wrangle with the world, made themselves felt in the examples which he gathered from his Greek authors, and when the examples did not fit, he altered them to suit his mood—and fooled the men who copied him blindly. This was made known to me when I was a student in Berlin sixty odd years ago and it lent a new interest to a book, which gave me my first interest in syntax, and I sometimes wonder how many suspect that there is a human document in a schoolbook that came into the world shortly after the great conflict of the Civil War, out of which the author, who was not a mere compiler, emerged, crippled in body, shattered in fortune, with teeth set hard to meet the stress of fate, his eyes wet with tears for his fallen comrades; and yet with the gleam of a new love reflected in their depths. In the examples of my Latin Grammar of 1867 lies perdu the history of that period of my life. The first page of the Syntax shows my attitude towards the Civil War by a quotation from Ovid, <Non> tam | turpe fuit vinci quam contendisse decorum est (A.J.P. XXXV 234), and the poet of love is accountable for many examples of a different kind. The book is a breviary of love. My friend, Professor March, used to say that Hamlet belonged to Shakespeare's earlier period by reason of the large part that love plays in the drama, and anyone interested in the story of my life might recognize my state of mind in the many quotations from Ovid and Propertius. If the period of disillusionment should ever come, I said to myself, Krueger is at hand.
