Events are ontologically dependent entities in the sense that they existentially depend on their participants in order to exist. Take for instance the event e: the stabbing of Caesar by Brutus. In this event we have the participation of Caesar himself, of Brutus and of the knife. In this case, e is composed of the individual participation of each of these entities. Each of these participations is itself an event that can be complex or atomic but which existentially depends on a single substantial. It is important to emphasize that being atomic and being instantaneous are orthogonal notions in this framework, i.e., atomic participations can be time-extended as well as an instantaneous event can be composed of multiple (instantaneous) participations.
