OpenLearn timeline for the unit A219_1: Introducing the Classical world. This unit aims to get you started on exploring the Classical World by introducing you to the sources upon which you can build your knowledge and understanding. The unit also gets you started on an exploration of both time and space in the Classical world. In this unit we illustrate some of the issues that arise in connection with timelines, so you will be working with a 'general' timeline as an example. The following timeline should give you a flavour of working with timelines. This timeline is available for you to contribute to. As you work through it think about what sort of entries have been entered on the timeline.
