Considering that Arrian was the only historian that was remotely close to Alexander and his era he will have to do. I can't help but hope that more sources will be revealed though. It would be great if historians had a cross reference and we might finally solve the mystery of Alexander's tomb.
As historians go regarding Alexander,I found that Arrian is one of the more credible. There are other sources who also have done as Arrian, and used information which had been preserved for safekeeping and posterity. All the so called sources are secondhand and therefore generally suspect. But Arrian explains himself well, explains his sources, and seems to try to be fair and impartial. I actually counted the number of times he mentions the altars that Alexander erects to make his religious duties. That has been a basis for my novel on Alexander as I believe that he is driven by a religious cause to achieve his goals.
That's of the earth, silly, actually ancient Greece. Wiseabove, literally/figuratively, to see wherest thou goest. Make the RITE choice, gorgeous. Meet me in Heaven, girl, where I shall kiss your wonderful, adorable feet for ‘aperitif’ (like an ‘appetizer’ for what’s come’n). This earth is just passing away, as our age shows: born one day, croak 88ish years later. What we do in this finite existence? Determines how our Divine Judgment goes, whether we achieve Heaven. If we make Heaven? Kick-some-ass. I’ll be having a BIG-ol, woohoo, party-hardy, too, celebrating our resurrection for eons and eons, fulla nekk’n and luvin, drinkin and dancing and nekk’dness - clothes will be optional. Wanna come? You’re most invited, babe --- The difficult part of our journey toward the Light? Ready or not, we ALL must succumb to death sometime somewhere someday. Pray for me, k? I pray for you everyday. God bless you.
