Marcus Octavius was at the bidding
of Gracchus removed by the lictors from the tribunes' bench; and then,
amidst universal rejoicing, the agrarian law was carried and the
first allotment-commissioners were nominated. The votes fell on the
author of the law along with his brother Gaius, who was only twenty
years of age, and his father-in-law Appius Claudius.
Such a family-
selection augmented the exasperation of the aristocracy. When the
new magistrates applied as usual to the senate to obtain the moneys
for their equipment and for their daily allowance, the former was
refused, and a daily allowance was assigned to them of 24 -asses-
(1 shilling).
The feud spread daily more and more, and became
more envenomed and more personal. The difficult and intricate task
of defining, resuming, and distributing the domains carried strife
into every burgess-community, and even into the allied Italian towns.
