Our scientific discourse aims to rehabilitate the national literary heritage of the valuable work of Sergiu Matei Nica: a Romanian poet, prose writer and publicist from Bessarabia, one of the most talented and least known Bessarabian writers of the Romanian interwar period, part of the generationist movement of the mid-30s of the 20th century, who aimed to rehabilitate the literary prestige of the province of Bessarabia and to give new and special personality to the Bessarabian spirituality. The writer’s diary, left in seven handwritten notebooks, covering the period 1968-1973 and including diaristic notes (from his youth, from the front or from prison), essays, position papers, opinions on literary, social and political life, is a memoir of great historical and literary documentary value for its richness and uniqueness. At the beginning of our doctoral research, we chose to analyse unpublished pages from Sergiu Matei Nica’s last diary-notebook.
