Aims. The question of the different oscillation periods for global modes of quiescent prominences is discussed.
Methods. Simple 1D prominence configurations are used to describe the magnetohydrostatic equilibrium and their oscillations for small amplitudes.
Results. Three basic modes of oscillations were found and their periods as a function of the magnetic field configuration and the assumed geometry are given.
Key words: Sun: prominences
