Abstract
In recent times there has been a strong revival of interest in spectropolarimetric observations of solar prominences. This is due to the fact that new instruments, with unprecedented spectral resolution and polarimetric accuracy, are now available to solar physicists. These instruments open for the first time the possibility of unveiling the fine structure of magnetic fields and its correlation with velocity fields and density inhomogeneities in these fascinating objects. The interpretation of spectropolarimetric observations of solar prominences still stands, however, as one of the most challenging problems of what is nowadays known as atomic astrophysics, or, in other words, modern atomic physics applied to the diagnostic of astronomical objects. In this brief review, a hystorical account of the measurements of magnetic fields in prominences is given, and the present status of the theory, which stands at the basis of the interpretation of the observations, is dicussed. Some perspectives for future investigations are also presented.
