Stupid question I'm sure:
is a title of a book always in the ablative absolute, because there is no further connection to the sentence (in the obvious absence of a sentence)? or is it just that because a lot of titles start with 'de' that they are in the ablative?
“Cum ego verbo utar,” Humpty Dumpty dixit voce contempta, “indicat illud quod optem – nec plus nec minus.”
“Est tamen rogatio” dixit Alice, “an efficere verba tot res indicare possis.”
“Rogatio est, “Humpty Dumpty responsit, “quae fiat magister – id cunctum est.”
