[ULPIANUS libro primo institutionum. ] §1.6.4.prNam ciuium Romanorum quidam sunt patres familiarum, alii filii familiarum, quaedam matres familiarum, quaedam filiae familiarum.
[ULPIAN in the first book of the Institutes.] For of Roman citizens, some are fathers of families, others sons of families, some mothers of families, others daughters of families.
patres familiarum sunt, qui sunt suae potestatis siue puberes siue impuberes: simili modo matres familiarum: filii familiarum et filiae, quae sunt in aliena potestate.
Fathers of families are those who are of their own right, whether of pubertal age or below pubertal age; in like manner, mothers of families. Sons and daughters of families are those who are under the power of another.
nam qui ex me et uxore mea nascitur, in mea potestate est: item qui ex filio meo et uxore eius nascitur, id est nepos meus et neptis, aeque in mea sunt potestate, et pronepos et proneptis et deinceps ceteri.
For whoever is born from me and my wife is in my power; likewise, whoever is born from my son and his wife, that is, my grandson and granddaughter, are equally in my power, as well as a great-grandson and a great-granddaughter, and so on in succession.
