[GAIUS libro quarto ad legem duodecim tabularum. ] §47.22.4.prSodales sunt, qui eiusdem collegii sunt: quam Graeci ἑταιρείαν uocant.
[GAIUS in the fourth book on the Law of the Twelve Tables.] are those who belong to the same collegium; which the Greeks call ἑταιρεία.
his autem potestatem facit lex pactionem quam uelint sibi ferre, dum ne quid ex publica lege corrumpant.
Moreover, the law gives them the power to make for themselves any agreement they wish, provided that they do not violate any part of the public law.
sed haec lex uidetur ex lege Solonis tralata esse.
But this law seems to have been translated from the law of Solon.
nam illuc ita est: ἐὰν δὲ δῆμος ἢ φράτορες ἢ ἱερῶν ὀργίων ἢ ναῦται ἢ σύσσιτοι ἢ ὁμόταφοι ἢ θιασῶται ἢ ἐπὶ λείαν οἰχόμενοι ἢ εἰς ἐμπορίαν, ὅτι ἂν τούτων διαθῶνται πρὸς ἀλλήλους, κύριον εἶναι, ἐὰν μὴ ἀπαγορεύσῃ δημόσια γράμματα.
For there it is written as follows: "And if a deme, or members of a phratry, or those associated for sacred rites, or sailors, or messmates, or those sharing a common tomb, or members of a religious guild, or those setting out for booty or for trade, make any agreement among themselves, it shall be valid, unless public written laws forbid it."
