We propose spectroscopy and imaging of the four components of the candidate gravitational lens 1422+231. This is the brightest of the few known examples of subarcsecond multiply imaged quasars. It was selected from a survey of 1750 flat spectrum radio sources which should be particularly effective at finding subarcsecond lenses. With V = 16.5 (all components) and z = 3.62, this is one of the most apparently luminous objects in the universe. Spectroscopy of optical counterparts to the four radio components will clearly establish whether or not the system is a gravitational lens, and imaging with the FOC is very likely to identify the lens, even if it is a highly subluminous galaxy. Contamination due to spilled light is not a problem for the brightest three components, and for the faintest component, we will measure contamination due to the other three components with an offset sky exposure. A system with four components offers the prospect of a large number of constraints on the lensing model. Moreover, the radio sources are compact and highly polarized, and so very likely to be variable. 1422+231 could therefore be used in a VLA or VLBA monitoring campaign to derive a new estimate of the Hubble constant using up to three time delays. Confirmation of the lens can only be done from space.
