A blast from the past, 1982 to be precise. Back when intros and outros were full-blown music productions and a contender for one of the greatest soundtracks of all time, this epic was also syndicated in French and later English. Something kids would rush home from school to watch!

The opening narration begins:

It is the 16th century. From all over Europe, great ships sail west to conquer the New World, the Americas. The men, eager to seek their fortune, to find new adventures in new lands. They long to cross uncharted seas and discover unknown countries, to find secret gold on a mountain trail high in the Andes. They dream of following the path of the setting sun that leads to El Dorado and the Mysterious Cities of Gold.

If you’re inclined, you can find full series ‘around’ the internet, but be warned, sadly, the original tapes were lost and were later re-dubbed!

Still, an epic worth watching, and was considered normal TV scheduling at the time rather than specialist anime content!
