Though not the first to write this hybrid kind of nonsense, Edward Lear developed and popularized it in his many limericks (starting with "A Book of Nonsense", 1846) and other famous texts such as "The Owl and the Pussycat", "The Dong with a Luminous Nose," "" and "The Story of the Four Little Children Who Went Around the World".

Carroll's poem "Jabberwocky", which appears in the latter book, is often considered quintessential
Luminous intensity Luminous intensity In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit. Photometry deals with the measurement of visible light as perceived by human eyes. The human eye can only see light in the visible spectrum and has different sensitivities to light of different wavelengths within the spectrum. When adapted for bright conditions (photopic vision), the eye
