Opening Acts, Opening Scenes

Jonson's Volpone, Acts I and II--Opening acts are useful to compare.  In Marlowe's Dr. Faustus, Act I, Scene 1 establishes the protagonist's glorious vision of powers and places that he thinks magic will make available to him.  Shakespeare's King Lear uses Act I to establish Kent's steadfast loyalty, Gloucester's gullibility, Cordelia's mute honesty, and the courtly sophistication of Edmund, Goneril and Regan.  Marlowe used his first act's first scene to let his protagonist fire off gorgeous soliloquies to reveal Faustus' value system, that megalomaniacal pursuit of power to the exclusion of all other studies.  What mnemonic spectacle is Jonson creating when he begins the play with Volpone's ironic "dawn song" and "hymn of praise" to his hoarded gold?  What "reader-rules" does Jonson establish with the speeches in this scene, and what do they predict will happen in Acts II-V?
