Great point!
Posidonius of Rhodes was known as the greatest polymath of the age (according to the wiki, "He came near to mastering all the knowledge of his time"!), and was a pioneer in pretty much every field. While he's often classified as a Stoic, he rejected the Stoic view of emotion and embraced a view closer to that of Plato and Aristotle,
making him more of an Eclectic. When Cicero goes on his tour of Greece and Asia Minor, he will study with Posidonius during his stay in Rhodes.
I disagree -- a simple military tribune is more often an
equites, so it would be notable if we declined to run as a patrician. Also, the broad-striped tribune is second-in-command of a legion, so if the commander is ever indisposed, we will be able to gain direct command experience even from a young age.
Huh. According to
the wiki, Caesar was born in 100 BC and "was elected Quaestor for the year 69 BC", making him... 31 years of age? That might be due to the 10-year requirement for tribune -- the wiki says that Caesar was elected tribune "on his return to Rome" but that his intended return in 78 BC was delayed when his ship was attacked and he was taken captive by pirates. That captivity might have delayed him (and his political ambitions) by a year.
On the other hand, he was elected curule aedile in 65 BC (age: 35 years old), served as praetor in 62 BC (age: 38 years old), and sought election as consul for the year 59 BC -- each of these is one year below the usual minimum age, but one year
older than the minimum age for patricians. All that to say: I don't think Julius Caesar ascended the
cursus honorum 'in his year' at all.
