The present study analyzes Amitav Ghosh's work, In an Antique Land (1992), as an alternative form of historiography narrative which questions the existing demarcations between historical facts, literary fiction, and ethnographic knowledge. The paper seeks to fill the gap in the literature on the need for a comprehensive analysis of the interplay between archival fragments, narrative construction, subaltern representation, ethnographic reflexivity, temporal hybridity, and cultural mediation in the selected text. Qualitative textual analysis is used in the study, especially in the reconstruction of Bomma's history through archival fragments, construction of medieval and contemporary narratives, Ghosh's ethnographic engagements, and representation of linguistic and cultural differences. Through this analysis, one can understand how Ghosh utilizes fragmentary evidence and narrative construction to make known the mediated nature of historical knowledge. The portrayal of Bomma shows not only what is possible but also what is problematic in trying to retrieve marginalized histories, with ethnographic reflexivity bringing into question any notion of culturally distant observation. In addition, temporal change and translation indicate the instability of history and culture. In conclusion, one can understand how the hybrid form of narration in In an Antique Land serves as a historiographical strategy by which Ghosh problematizes historical authority and archival silences.
