What were poets invited to bring the first tragedies in fifth century BC Greece there they performed as part of festivals honoring dionysus greek god vegetarian and wine?

You're close! The god being honored is Dionysus, the god of wine, theater, and fertility, not vegetarianism. While Dionysus was associated with wine, it's important to note that ancient Greek beliefs about vegetarianism were not as strict or widespread as in some modern cultures.

Here's what poets brought to the tragic performances:

* Dithyrambs: These were choral hymns originally dedicated to Dionysus. Over time, they evolved into the format of tragedy.

* Stories: The tragedies themselves were stories, often featuring mythical heroes, their struggles, and their fates.

* Actors: The poets themselves would typically be the ones who wrote the plays, directed them, and even acted in them.

* Costumes: Elaborate costumes were used to represent the characters and their roles.

* Masks: Masks were essential for conveying emotion and for allowing actors to play multiple roles.

The festivals honoring Dionysus were called "City Dionysia." These festivals were held in Athens and other Greek cities, and they were a major event in the civic calendar. Tragedy competitions were a key part of these festivals, and poets competed for prizes and recognition.
