Note 6 — LIFE OF CRASSUS.
George Long translation
Kaltwasser makes this passage mean that Crassus merely took his brother's wife and her children to live with him; which is contrary to the usual sense of the Greek words and readers the following sentence unmeaning.
Kaltwasser observes that we do not know that such marriages were in use among the Romans. I know no rule by which they were forbidden. (Gaius, i. 58, &c.)
