I need 2 traditions of Ancient Greek

Engagement which is a tradition when a man has to first ask a hand of a woman from her father before marriage, which was mostly common in smaller towns and villages.

Tradition of giving other person a knife. In Greece there is a belief that you should not directly give a knife to someone, but put it on the table so he/she can pick it up, because giving a knife directly might start a fight.

Umm, Lyric poetry history, tragedy and comedy I think
