The titles of all their works show an exuberance which is really singular. I possess one of eighteen lines, not counting a note included in the title-page itself, and intended to explain it. A socialistic work published in Australia, by an Italian, and in pure Italian, has a title arranged in the shape of a triumphal arch. It is precisely in the title-page that nearly all of them at once betray the taint of madness. This example--from the work of the mattoid Démons--will suffice: “The demonstration of the fourth part of nothing is something; everything is the quintessence extracted from the quarter of nothing and that which depends on it, containing the precepts of the holy, magic, and devout invocations of Démons, to discover the origin of the evils which afflict France.” Many have the crotchet of mixing up with their sentences accumulated series of numbers, which is also sometimes done by paralytics. In a mad production of Sovbira’s, entitled “666,” all the verses are accompanied by the number 666. The strange thing is that, at the same time, a certain Porter, in England, had published a work on the number 666, declaring it the most exquisite and perfect of numbers.[345] Lazzaretti, too, had a singular partiality for this number. Spandri, Levron, and C---- have a similar preference for the number 3. A special characteristic found in mattoids, and also, as we have already seen, in the insane, is that of repeating some words or phrases hundreds of times in the same page. Thus, in one of Passanante’s chapters, the word _riprovate_ occurs about 143 times. Some have had special paper manufactured for their works, like Wirgman, who had it made with different colours on the same sheet, at an enormous increase of expense, so that a volume of four hundred pages cost him over £2,200 sterling. Filon had every page of his book of a different colour. Another characteristic is that of employing an orthography and caligraphy peculiar to themselves, with words in large type or underlined. They will sometimes write even private letters in double column, or with vertical lines traversed by horizontal and sometimes by diagonal ones. They sometimes underline one letter in preference to others in the same word (Passanante), or they write in detached verses like those of the Bible, or introduce points after every two or three words, as in the MS. (in my possession) of a certain Bellone, or parentheses, even one within the other, as Madrolle used to do, or notes upon notes, even in the title-page, as in the case of Cas---- and of La----. The latter (a University professor) in a work of twelve pages has nine consisting of notes alone. Hepain invented a _physiological_ language, which consists in the main of our own letters reversed, and of numbers used in their places. Many have a caligraphy quite peculiar to themselves, close, continuous, with lengthened letters, and always extremely legible.
