Aégis is the third studio album by Norwegian gothic metal band Theatre of Tragedy, and the last album of their musical period defined by gothic stylings and Early Modern English lyrics.
As with Theatre of Tragedy's previous albums, the lyrics are written in Early Modern English (except "Venus", in Latin) which sounds very different from modern English: Vaunt! - Devil tyne - Wadst thou wane fore'ermae? (from the song "Angélique"). The subject matter is drawn from a range of European folklore and history: Venus and Poppæa are from Roman sources; Aœde, Cassandra, Bacchante and Siren are drawn from Greek mythology; while Lorelei refers to a Nix from German stories, and Angélique is inspired by medieval poem Orlando Furioso.
From this period there were 2 releases.
