Pliny the Elder (23–79 AD) in his "Natural History" mentions a "port of the Achæi" and an "island of Achilles", famous for the tomb of that "man" (), situated somewhat nearby Olbia and the Dnieper-Bug Estuary; furthermore, at 125 Roman miles from this island, he places a peninsula "which stretches forth in the shape of a sword" obliquely, called "Dromos Achilleos" (Ἀχιλλέως δρόμος, "Achilléōs drómos" "the Race-course of Achilles") and considered the place of the hero's exercise or of games instituted by him. This last feature of Pliny's account is considered to be the iconic spit, called today "Tendra" (or "Kosa Tendra" and "Kosa Djarilgatch"), situated between the mouth of the Dnieper and Karkinit Bay, but which is hardly 125 Roman miles (c. 185 km) away from the Dnieper-Bug estuary, as Pliny states. (To the "Race-course" he gives a length of 80 miles, c. 120 km, whereas the spit measures c. 70 km today.)
