Panathenaia is a really big party that happened every year in ancient Athens, Greece. The party was held to celebrate the goddess Athena's birthday. Athena was really important to the people of Athens because they believed she was the goddess of wisdom, art, and war.
The Panathenaia party lasted for a whole week and was full of fun things to do. People from all over Greece came to celebrate with music, dancing, and sports competitions. There were chariot races, foot races, and even a wrestling competition.
The most important part of the Panathenaia celebration was when the people of Athens took a special cloth robe and put it on a statue of Athena. This robe was called a "peplos". They also offered the goddess a big cake called a "pogata". This was how they showed Athena how much they loved and respected her.
Overall, the Panathenaia party was a really fun and happy time for the people of Athens to celebrate their gods and show their pride in their city.
