Plutarch De fraterno amore 1

[1] THE ancient statues of Castor and Pollux are called by the Spartans Docana; and they are two pieces of wood one over against the other joined with two other cross ends, and the community and undividedness of this consecrated representation seems to resemble the fraternal love of these two Gods. In like manner do I devote this discourse of Brotherly Love to you, Nigrinus and Quintus, as a gift in common betwixt you both, who well deserve it. For as to the things it advises to, you will, while you already practise them, seem rather to give your testimonies to them than to be exhorted by them. And the satisfaction you have from well-doing will give the more firm durance to your judgment, when you shall find yourselves approved by wise and judicious spectators. Aristarchus the father of Theodectes said indeed once, by way of flout of the Sophists, that formerly there were scarce seven Sophists to be found, but that in his time there could hardly be found so many who were not Sophists. But I see brotherly love is as scarce in our days as brotherly hatred was in ancient times, the instances of which have been publicly exposed in tragedies and public shows for their strangeness. But all in our times, when they have fortuned to have good brothers, do no less admire them than the famed Molionidae, that are supposed to have been born with their bodies joined with each other. And to enjoy in common their fathers’ wealth, friends, and slaves is looked upon as incredible and prodigious, as if one soul should make use of the hands, feet, and eyes of two bodies.
