The timeline is a multilingual platform to allow users to visualise milestones and key examples of historical practices, artefacts, technologies and buildings. The online version is based on an open communication platform usable across Europe, mapping the contexts and influences of specific phenomenon of theatre practices and technologies as cultural heritage.

An extensive filtering system makes it possible to view the entries from different perspectives. The filtering can be based on a country, a technology, a discipline, people, relations, and so on. This innovative approach makes it possible to discover new relations, tracking the interconnecting relationships and influences of practices and technologies through time and space.
