This dissertation approaches the work of mourning - which follows one`s anguish of losing love or ideal - as a possible via to prepare the end of an analysis. Such work implies making the subject available to the transitoriness of the object and to the contingency of the phallus. We will attempt to highlight how this task is processed and which object it happens to involve. We will study how the melancholy solution carries this subject`s difficulty in the face of this object. In order to reach our goals, we will adopt the Freudian perspective about the object, and Lacan`s contributions, mainly the ones related to his formulations on the theme.
