An excerpt from chapter 3 (New Lands, New Opportunities) of On Eirehann...
Alsandair of the Blue Sea was one of the most eccentric things ever produced by the Emerald Isle. The sometimes brilliant, often mad son of a druid is well known for his incredible variety and bewildering success. The youngest person to ever successfully run for Mayor (at age 22), Alsandair's numerous oddities included suggesting that hollow poles made of iron be laid in his village to deliver water to the people (the idea was rejected as a fanciful waste of the small town's resources), his belief in a single deity (for which he was charged with heresy, but the Temple's increasing monotheistic leanings combined with his powerful oratory ability lead to the charges being dropped - see chapter 4, The Temple of Dagda, for more information about his affect on religious doctrine), and his numerous pseudo-scientific/philosophical writings (including the belief that veins, nerves, and arteries carried blood, nervous spirits, and animal spirits, respectively). However, one of his least celebrated achievements is arguably one of his most important (for more on his other achievements, the author suggests Madman and Monarch: Alsandair of the Blue Sea).
In 705 BC, Alsandair was struck with a powerful urge to explore. He had built up a sizeable fortune through public service and had, through some experiments with agriculture, made his village on of the most productive in the kingdom. He petitioned the King, who was then concerned with his new cities on the Iberian peninsula, for diplomatic status for a voyage through the Mediterranean. Believing little would come of it, the King was not terribly eager to send away one of his best minds, but Alsandair would not be dissuaded. And so the king granted Alsandair status as Ambassador of the High King and a small contigent of bodyguards.
Accordingly, Alsandair set out in 704 BC leading a small fleet commissioned entirely from his own pocket. His first stop was in Tartessos, where he saw firsthand the pro's and con's of a merchant oligarchy. He noted the freedom of their markets, writing down what worked and what he thought could use improvement. From there he sailed to the various lesser ports of Carthage before making his way to the capitol itself. He made his diplomatic embassage, as well as some connections with merchants he would reserve for later use, and moved on the Syracuse for resupply (and networking), before putting in at one of the ports servicing Rome.
Alsandair was marvelled by the Great City. He made notes on everything from Roman architecture, to literature, to social class distinctions. He met with the merchant elite, the artisans of the city, he was even granted a singular treat of a short tour of the Imperial Library itself. His experiences in Rome would influence his thinking for the rest of his life.
After making valuable connections with the merchant elite of Rome, the locals pointed him in the direction of Greece and the Spartan lands. These fierce warrior peoples also fascinated him and he documented their lifestyles and was privy to as many customs as he could talk his way into. He noted how their training was a way of life and supreme importance of the state over the individual life.
His next stop was the lands of the Sea Peoples, a vast conquering federation of tribes that nonetheless bred shrewd traders. His interest here ranked second only to Rome. He took copious notes on the history of the Sea Peoples and their conquests and traveled up and down the Levant noting the peculiar style of the buildings, among many other things.
His final stop would be perhaps his most important, for it was in Egypt that Alsandair used his diplomatic and mercantile skills to obtain an offer by the Egyptian Pharaoh to sell the new weaponry the Tartessos employed for a very reasonable price. He made a great many friends and set up trade connections that would prove very profitable for him personally.
Subsequent years would find Alsandair traveling to far away Atyrian and Byzantine ports, but these longer distances took more time to develop and Alsandair himself, while very interested in Atyrian merchant culture and wrote a number of things about them, was already heavily invested in other areas and had far less free time to spend in these nations.
