Our perception of the Holy Grail is, for the most part, the result of orthodox views that have dominated literary interpretation. However, the first appearance of the Holy Grail in literature does not conform to the orthodox rules and traditions. In fact, the narrative of Perceval is filled with evidence that points to a very different form of Christianity, one that would have been considered heretical at the time that Chrétien de Troyes was writing it. The twelfth century in France is often called the "Golden Age" of heresies. As Manichaeism and Bogolism swept through the country, they gave birth to a new heresy, that of Catharism. A defining factor shared by these three heresies is dualism, a belief in two gods, one being good and the other evil. These beliefs can all be traced to early Christianity and to groups who believed that they were the true followers of Christ. This study seeks to look at evidence of these beliefs in Perceval, while showing at the same time the implausibility of an orthodox interpretation. Research for this study extends to the beginnings of Christianity, more specifically to Gnostic beliefs. It also looks at other religious influences in France in the eleventh and twelfth centuries, and at the Cathars. It examines what little we know about Chrétien de Troyes and the likelihood that he was influenced by heretical beliefs. In conclusion, it offers a new perspective on the Grail narrative and the mystery that surrounds Chrétien's famously unfinished work. Through exploration of knowledge, the treatment of women, and the famous "grail" scene, we demonstrate the prevalence of Gnostic influences, and how these influences were likely to occur at the time. Although the true essence of the Grail may always remain a mystery, this study offers an "unorthodox" outlook on what has become a predominantly "orthodox" symbol.

GRAIL is a Java library for capturing and manipulating graphs. It is used in the VizzAnalyzer reengineering tool developed at Växjö University that allows quality analysis of software systems. GXL is a standard exchange format for software data in graph structure, mainly used within the field of software reengineering that is widely supported in other tools within the same field. It is important for VizzAnalyzer to support GXL as an exchange format to allow collaboration with other tools on this basis. As the goal of this thesis, a GXL graph serializer/deserialize architecture for GRAIL has been developed that allows data exchange between VizzAnalyzer and other tools that support the GXL format. VizzAnalyzer is capable of analyzing large software systems and therefore the task required special attention on high performance and low memory footprint even with large GXL graph structures.

In this thesis an approach to visualize internal behaviour of object oriented software is developed. The runtime information, which can be described as objects calling other objects, is displayed as a graph consisting of nodes and edges. The aim is to design an application in Java, which takes the runtime information in form of an object call graph and visualizes it as a tree and as a force directed view. Therefore, first a data model has to be designed, holding an object call sequence. Furthermore, a discussion about graph definition languages and according tools is made. After this different graph layout algorithms are examined as well as graph displaying tools. Finally, the implementation of this visualization program deals with the combination of these three components graph data extraction, graph layout calculation and graph visualization.
