<head>VIII. Affairs of Asia</head><head>The River Oxus</head>The Apasiacae inhabit the district between the Oxus and Tanaïs, the former of which rivers falls into the Hyrcanian Sea, while the Tanaïs falls into the <a class="linkToPlace" target="_blank" href="/place?placename=Palus&groupId=830&placeId=1500">Palus</a> Maeotis. Both are large enough to be navigable,
and it is considered marvellous how the nomads passing the Oxus on foot with their horses reach <a class="linkToPlace" target="_blank" href="/place?placename=Hyrcania&groupId=640&placeId=1172">Hyrcania</a>.
There are two stories regarding this, one reasonably probable and the other very surprising, but yet not impossible.
The Oxus, I should say, rises in the Caucasus, but in traversing Bactria greatly increases in volume owing to the number of tributaries it receives, and henceforth runs through the plain with a strong and turbid current.
Reaching in the desert a certain precipice it projects its stream, owing to the volume of the current and the height of the fall, so far from the crest of the cataract that in falling it leaps to a distance of more than a stade from the bottom of the precipice.
It is in this place that they say the Apasiacae pass dry-shod with their horses to <a class="linkToPlace" target="_blank" href="/place?placename=Hyrcania&groupId=640&placeId=1172">Hyrcania</a>, skirting the precipice under the waterfall.
There is more reasonable probability in the second account than in the first. They say there are at the foot of the cataract large slabs of rock on which the river falls, and by the force of the current hollows out and pierces these rocks for some depth and flows underground for a short distance, after which it comes to the surface again.
The barbarians are acquainted with this and cross to <a class="linkToPlace" target="_blank" href="/place?placename=Hyrcania&groupId=640&placeId=1172">Hyrcania</a> with their horses at the place where the river thus interrupts its course.
