17 According to Scognamiglio (loc. cit. p. 49) reference is made to this episode in an obscure and even variously interpreted passage of the Codex Atlanticus:" Quando io feci Domened-dio putto voi mi nietteste in prigione, ora s 'io lo fo grande, vol mi farete peggio. "

22 "Such transfiguration of science and of nature into emotions, or one might say, religion, is one of the characteristic traits of da Vinci's manuscripts, which one finds expressed hundreds of times." Solmi: "La resurrezione, etc.", p. 11.
23 "La resurrezione, etc.", p. 8: "Leonardo placed the study of nature as a precept to painting . . . later the passion for study became dominating, he no longer wished to acquire science for art, but science for science's sake."
24 For an enumeration of his scientific attainments see Marie Herz-feld's interesting introduction (Jena, 1906) to the essays of the Confer cnze Florentine, 1910, and elsewhere.
25 For a corroboration of this improbable sounding assertion see the "Analysis of the phobia of a five-year-old boy," Jahrbuch fur psychoanalytische und psychopadiologische Forschungen, Bd. I, 1909, and the similar observation in Bd. II, 1910. In an essay concerning "Infantile Theories of Sex" (Sammlungen kleiner Schriften zur Neurosenlehre, p. 167, Second Series, 1909), I wrote: "But this reasoning and doubting serves as a model for all later intellectual work in problems, and the first failure acts as a paralyzer for all times."
26 Scognamigiio Joe. eit, p. 15.
27 Cited by Scognamigiio from the Codex Adantieus, p. 65: "Questo scriver si distintamente del nibio par ehe sia mio destino, perche nella mia prima ricordatione della mia in-fantia e mi pare a ehe essendo io in eulla, ehe un nibio venissi a me e mi aprissi la bocca eolla sua eoda e molte volte mi per-euotesse eon tal eoda dentro alle labbra.
