"Aaron the Orthodox" aka Harun al-Rashid was known for his vast treasures amassed from trading with European Royalty and Nobility
“A Frankish mission came to offer Harun friendship in 799.
Harun sent various presents with the emissaries on their return to Charlemagne's court, including a clock that Charlemagne and his retinue deemed to be a conjuration because of the sounds it emanated and the tricks it displayed every time an hour ticked “
“………….the envoys travelling between Harun's and Charlemagne's courts, amicable discussions concerning Christian access to the Holy Land and the exchange of gifts.
Notker mentions Charlemagne sent Harun Spanish horses, colorful Frisian cloaks and impressive hunting dogs. In 802 Harun sent Charlemagne a present consisting of silks, brass candelabra, perfume, balsam, ivory chessmen, a colossal tent with many-colored curtains, an elephant named Abul-Abbas, and a water clock that marked the hours by dropping bronze balls into a bowl, as mechanical knights—one for each hour—emerged from little doors which shut behind them. The presents were unprecedented in Western Europe and may have influenced Carolingian art.”
They also had the most advanced technologies of their time. (…including art and building trades, ship building, cartography and trading routes, etc, etc)
