He took Rabirius with him, and, in order to secure the repayment, the latter was made superintendent (dioikaetaes) of the Egyptian revenues[147].

Unluckily for him, his wily debtor did after all turn against him, and he escaped from Egypt with difficulty and with the loss of all his wealth.

When Gabinius was accused de repetundis and found guilty of accepting enormous sums from Ptolemy, Rabirius was involved in the same prosecution as having received part of the money; Cicero defended him, and as it seems with success, on the plea that equites were not liable to prosecution under the lex Julia.

Towards the end of his speech he drew a clever picture of his unlucky client's misfortunes, and declared that he would have had to quit the Forum, i.e.to leave the Stock Exchange in disgrace, if Caesar had not come to his rescue by placing large sums at his disposal.
What Rabirius did was simply to gamble on a gigantic scale, and get others to gamble with him.

The luck turned against him, and he came utterly to grief.
