The view that Gothic literature emerged as a reaction against the prominence of the Greek classics, and that, as a result, it bears no trace of their influence, is a commonplace in Gothic studies. This thesis re-examines this view, arguing that the Gothic and the Classical were not in opposition to one another, and that Greek tragic poetry and myth should be counted among the literary sources that inspired early Gothic writers. The discussion is organised in three parts. Part I focuses on evidence which suggests that the Gothic and the Hellenic were closely associated in the minds of several British literati both on a political and aesthetic level. As is shown, the coincidence of the Hellenic with the Gothic revival in the second half of the eighteenth century inspired them not only to trace common ground between the Greek and Gothic traditions, but also to look at Greek tragic poetry and myth through Gothic eyes, bringing to light an unruly, ‘Dionysian’ world that suited their taste. The particulars of this coincidence, which has not thus far been discussed in Gothic studies, as well as evidence which suggests that several early Gothic writers were influenced by Greek tragedy and myth, open up new avenues for research on the thematic and aesthetic heterogeneity of early Gothic literature. Parts II and III set out to explore this new ground and to support the main argument of this thesis by examining the influence of Greek tragic poetry and myth on the works of two early Gothic novelists and, in many ways, shapers of the genre, William Beckford and Matthew Gregory Lewis. Part II focuses on William Beckford’s Vathek and its indebtedness to Euripides’s Bacchae, and Part III on Matthew Gregory Lewis’s The Monk and its indebtedness to Sophocles’s Oedipus Tyrannus. As is discussed, Beckford and Lewis participated actively in both the Gothic and Hellenic revivals, producing highly imaginative works that blended material from the British and Greek literary traditions.

The life history of a population of Lutraria lutraria in a depth of 7m at Hunterston, Ayrshire is discussed. Much of the present population Is thought to have settled in 1967. The functional morphology of Lutraria is described and related to its life as a large, deep-burrowing bivalve. Lutraria spawned in late spring and continued to do so through the summer in 1979 and 1980. Animals became spent in August and September. Unsuccessful attempts were made to induce spawning in the laboratory. Artificial fertilization was successful but development did not proceed beyond the ciliated gastrula stage. Larvae of Lutraria were not identified in plankton samples and young stages were not encountered in sieved sediment samples. The biochemical cycle of the total animal and five component parts (gonad and visceral mass, digestive gland, adductor muscle, siphon and 'other' tissue) is investigated. A marked increase in weight, reflected in an increase in weight of the component parts, was recorded in Autumn 1979. This is thought to be related to an exceptional increase in the phytoplankton at this time. Although a relationship between the biochemical cycle and reproductive cycle remains uncertain, definite seasonal changes were recorded in the respiration rate of Lutraria. At 10°C, the maximum rate of a standard 20g animal was 0.1283m1s 02/g. dry wt./hr. in May 1980 and the minimum rate was 0.O59mls 02/g. dry wt./hr. in October 1980. The effect of temperature on respiration rate was also investigated. Significant differences were recorded for five experimental temperatures (10°C, 15°C, 20°C, 25°C and 30 °C) in August and October but only between two temperatures (10 C and 30 C) in April. There was a decrease in respiration rate at 30 C in August and October, but an increase in April. Respiration rate is affected by a reduction in oxygen tension. A variety of responses were recorded with a small degree of regulation shown. Individuals of Lutraria were able to survive 48 hours under anaerobic conditions. In fully oxygenated conditions heart rate ranged from 4-15 beats per minute with an average of 8 beats per minute. Heart beat was markedly affected by changes in temperature and oxygen tension, increasing to a maximum 22 beats per minute at 25 C, and decreasing to a minimum 2 beats per minute in anaerobic conditions. Heart rate is reduced (12 beats per minute to 5 beats per minute) on exposure to air. Lutraria exhibits an intermittent pattern of pumping activity. Under normal conditions 35% of the time is spent pumping and this Increases as oxygen is reduced (3.00mls 02/litre) to 65% of the time spent pumping. 15. Under normal conditions the respiratory flow varies between 0.382 litres per hour and 1.023 litres per hxir. Adult Lutraria maintain their ability to burrow, albeit slowly.
