on Thasos as being similarly arranged around a courtyard. Only a minority of the houses had evidence of staircases survive, demonstrating that they definitely had upper storeys, while for the remainder of Olynthian houses the evidence is inconclusive. On the Murder of Eratosthenes demonstrates that at least some Athenian houses also had an upper storey. Entranceways at Olynthos were designed for privacy, preventing passers-by from seeing inside the house. Historians have identified a "hearth-room" in ancient Greek houses as a centre of female activity. However, Lin Foxhall has argued that Greek houses often had no permanent kitchens. For example, a house in Attica known as the Vari House had multiple possible places which may have been used for cooking, but no fixed fireplace, and no one place was used for the entire lifetime of the house. Lisa Nevett points out that houses frequently had a "complex pattern of spatial usage", with rooms being used for multiple purposes. Family Men A man was the head (kyrios, ) of the household.

However, when any legitimate sons reached adulthood the role of kyrios could, in many instances, be transferred from the father to the next male generation. When a son was given his portion of the inheritance, either before or after his father had died, he was said to have formed a new oikos. Therefore, new oikoi were formed every generation and would continue to be perpetuated through marriage and childbirth. The relationship between father and son was bound intrinsically to the transfer of family property: a legitimate son could expect to inherit the property of his father and, in return, was legally obligated to provide for his father in his old age. If a son failed to care for his parents he could be prosecuted and a conviction would result in the loss of his citizen rights. However, sons were not compelled to maintain their fathers in their old age if they had not provided them with a skill. Furthermore, the heir to an inheritance would also be required to perform burial rites at the deceased's funeral and continue to provide annual commemorative rites. This would have
