Abstract: During the Renaissance there was a growing interest for the use of diagrams within conceptual studies. This paper investigates the historical and philosophical foundation
of this renewed use of diagrams in ontology as well as the modern relevance of this foundation. We discuss the historical and philosophical background for Jacob Lorhard's invention of the word
"ontology" as well as the scientific status of ontology in the 16th and 17th century. We also consider the use of Ramean style diagrams and diagrammatic ontology in general. A modern implementation
of Lorhard's ontology is discussed and this classical ontology is compared to some modern ontologies.
Abstract: Jacob Lorhard published his ontology in 1606. In this work the term ontologia ‘ontology’ was used for the first time ever. In this paper, it is argued that
Lorhard's ontology provides a useful key to the understanding of the early 17th-century world view in Protestant Europe. Among other things, Lorhard's ontology reflects how the relations between
scientific investigation and religious belief were seen. It is also argued that several of the conceptual choices which Lorhard made in order to establish his ontology may still be relevant for
modern makers of ontological systems. In particular, Lorhard's considerations on the notions of reality and time deserve modern reflections. Also his assumption of the educational value of
diagrammatical ontology deserves a modern discussion. Along with this paper an online hypertext version of Lorhard's ontology has been presented in order to create a useful tool for historical
research in early 17th-century thought and in order to illustrate the problems, which characterized the early attempt at establishing a diagrammatical approach to ontology.
