Aristobulus, more than a biographer

Aristobulus of Cassandreia has been listed among the many biographers of Alexander the Great (see: Eyewitness accounts of Alexander’s life), but he was far more than that. He did not hold any military function in Alexander’s army. Consequently, not being involved allowed him to approach the events as an onlooker. 

He must have been a tough guy since he survived the hardships of Alexander’s campaigns, including the march through the Gedrosian Desert. He seems to have lived to be over ninety years old. 

When he was 83, he began writing his book about the exploits of Alexander from the early days of his kinship to his death. He was blessed with an excellent memory, being able to recall so many events, novelties, and details! Apparently, his book was finished at about the same time as Ptolemy and Cleitarchus published theirs, 285-283 BC. Unfortunately, most of his work is lost. We only have a few scraps together with his observations recorded and used later by Arrian and Strabo. 

We may assume that Aristobulus’ accounts were exact and reliable. He had a wide field of interest and investigated the land, the animals, the many peoples he encountered, the public buildings, and other construction works. Alexander’s military campaign was not his priority. 

He is best known as the engineer/ architect in charge of restoring Cyrus’ Tomb in Pasargadae, a serious responsibility that clearly shows how much Alexander trusted his capabilities. 

Aristobulus, however, was mainly a geographer. He spent much time analyzing and describing the fauna and flora he encountered, the rainfall and the Indian monsoon (whose arrival he recorded in Taxila), the rivers, and the different climates. He drew an in-depth comparison between India and Egypt, including their environment. He analyzed the river courses, placing them in a broader context as trade routes throughout Central Asia and Punjab. 

The Oxus (see: Crossing the Oxus River), for instance, was the longest river, he said, that was navigable and used to transport goods from India to the Caspian Sea. Another river that caught his attention was the Polytimetus (see: Alexander's march to Maracanda) in Sogdiana, which did not flow into another river or a sea, but petered out in the desert. 

On the other hand, fragments of Aristobulus’ text on plants have been preserved. He tells us how rice was cultivated in beds in the backwaters and that the plants were 1.75 meters tall. He said that since each plant had several ears, the harvests were plentiful, adding that the grains had to be hulled. 

The geographer also spent ink on the importance of Alexander’s visit to Siwah. Unlike fellow biographers of the king, Aristobulus detailed Alexander’s route. Ptolemy stated that Alexander headed directly for Memphis. Aristobulus, instead, wrote that the king left from Paraetonium and followed the Mediterranean for about 290 kilometers before turning south to Siwah. On the way back, Alexander founded the city of Alexandria. This implies that he returned over the same route as the one used on his outward journey. Again, this is the version of events as copied by Arrian.

We know very little about Aristobulus’ fascinating personality, but he is one of the rare authors who draws an overwhelmingly positive picture of Alexander. He depicts him as a righteous king, concerned about justice and not making hasty decisions. Another of his remarkable declarations is that Alexander was not a heavy drinker but liked to spend time with his companions, toying with his drink. That is a far cry from the many statements or hearsay statements depicting Alexander as a heavy drinker and even that the wine led to his premature death in Babylon! 

Aristobulus rightfully declares that Alexander was under the protection of the gods. Nowadays, we would say that he was born under a lucky star. Why not?
