The paper consists of two parts: an interpretative commentary of carm. 9, 15 and a short sketch of a modell for ‘The decoding of poems as a sphere of resonance’. In the commentary of the poem the different intertexts, all leading back to one major hypotext, define the significance of the poem. In the modell I have tried to describe decoding poetry as a social practice on the basis of Michael Riffaterre’s modell of decoding poetry and Hartmut Rosa’s modell of the sphere of resonance.
