376. From the same cause Red warms, but Blue on the contrary does not. The calefaction given out in prismatic spectra of colours is an impure work, in which refractions, diversions and convergences of light, as well as demi-foci, cooperate. 377. The sun in the firmament may be viewed as the bright opening in the darkened chamber. Colours are therefore nothing but images of the sun in darkness, self-manifestations of the sun in dark matter. A point of light thrown into darkness is colour. This is the case around the sun, which is therefore surrounded by a hollow globe of colours, by its own refulgence. The rainbow is a ring around the sun consisting of infinite positions of the solar spectra in darkness. 378. The symbolical doctrine of the colours is correct according to the philosophy of nature. _Red_ is fire, love--Father. _Blue_ is air, truth and belief--Son. _Green_ is water, formation, hope--Ghost. These are the three cardinal virtues. _Yellow_ is earth, the Immoveable, Inexorable, falsity the only vice--Satan. There are three virtues, but only one vice. A result obtained by Physio-philosophy, whereof Pneumato-philosophy as yet augurs nothing. COLOURS AND PLANETS. 379. Every condensation of æther by light is consequently a production of colour, and inversely, every production of colour is a condensation of the æther. The laws of coloration run parallel with those of materialization, or, what is more, are the same. The planets are thus produced according to the laws which light exercises in the production of colours. 380. There are as many productions of heavenly bodies as there are of colours, and thus there are four. 381. The sun is the incorporation of Red or fire, the planets are that of the three terrestrial colours. The comets belong to the kingdom of darkness. 382. The planets are only suns reflected in darkness as in a mirror; they have originally been hollow globes of colour, then orbitar rings of colour (solar rainbows), then points of colour. The planets are coagulated colours, for they are coagulated light. At that very distance from the sun, where light begins to grow dim, where, to speak in the Newtonian sense, it begins to refract, there planetary mass originates. The mass of the planet thus coagulates together around the sun, but not in an uniform manner like a mass of pulp, but in pauses of colours, exactly like a rainbow.
