Lawrence Durrell's The Alexandria Quartet is regarded as the central work in his fiction. It has provoked critical commentary ever since the appearance of its individual volumes - Justine (1957), Balthazar (1958), Mountolive and Clea (1959) and the publication in a one-volume edition in 1962. Scores of Master's and PhD dissertations have been written since the 1960s on this most compelling and provocative novel. Today, The Alexandria Quartet stimulates critical discussion in works addressing the city, Durrell's representation of Alexandria, the theory of relativity, the role of memory, the recurring feature of the doppelgänger and the presence of the Gothic uncanny; his frequent references to D.H. Lawrence; his treatment of women characters; his interest in Gnosticism; and his own description of the Quartet as "a strange mixture of sex and the secret service". This volume of essays addresses all these themes, and brings together the mature work of four scholars on this central work of Durrell's fiction, together with two essays on its sequels, Tunc-Nunquam (1968-70) and The Avignon Quintet (1974-85).
