This paper looks at certain Greek laws mentioned by Plutarch, in order to examine whether
they were interpreted with complete juridical rigour. Thus, the following laws are analysed: the
nomoi agamiou, Solon’s law concerning to the exemption of the filial duty of feeding the father,
the illegitimacy of children of mixed marriages and the law of damages due to animals. This
study reveals that Plutarch committed certain mistakes because of chronological errors or lack
of juridical accuracy.
