At this point, Nicolaus of Damascus argued to Caesar that Archelaus acted appropriately and that Herod's will, supposedly written a few weeks prior (yielding the kingship to Archelaus and against Antipater), should be seen as valid. The change of this will in favor of Archelaus is given as Herod's true choice and, it is argued, occurred with Herod being in his right mind since he left the final decision to Caesar. The change of the will appears as one of Herod's last acts and it is attested from Jericho by one "Ptolemy", keeper of Herod's Seal. Nicholaus of Damascus had been Herod's confidant for years. He was loyal to Rome. Ptolemy was Nicholaus of Damascus' brother.
