Upon the same slight ground, Guil. Grotius builds the supposition, that the Calvisius mentioned by Pliny was the author of the This action was introduced, probably in the time of the republic, by some praetor of the name Calvisius (Hugo, R. R. G. p. 335), to protect the patron's rights of succession to a portion of his freedman's property against fraudulent alienations made in the lifetime of the freedman.
