It is sown that the electromagnetic field can be described within a quotient representation of the proper orthochronous Lorentz group. The relation of such a description with Majorana-Oppenheimer quantum electrodynamics and de Broglie-Jordan neutrino theory of light is discussed.10 pages, LaTeX2e, corrected version, to appear in Annales de la Fondation Louis de BroglieMathematical Physics15A66, 15A90text
