Ideas of how love is lived and how it should be lived vary depending on the different periods.

An ideal existed according to which friendships of childhood days should be the basis for erotic relationships and marriages. These studies explore which concepts of love, sexuality, and also of life, society and homeland were behind this conception and what followed from this as a consequence.
