The marriage at which the fateful apple is produced is unusual, being between a mortal man and a goddess. The failure to invite Eris, Strife (echoed in the fairytale of Sleeping Beauty), represents a dishonouring comparable with Tyndareus’ treatment of Aphrodite. The implication is that even destructive deities are essential to the psyche and to society, and will make their presence felt if denied. Similarly, strife is a necessary part of marriage. Eris is associated with Ares, god of war, who in turn is amorously connected to Aphrodite.
