Note 9 — Scene II.
Reading edition
[Strabo (Rerum Geog., lib. iii. 1807, p. 235) throws some doubt on the existence of these columns, which he suggests were islands or "pillar" rocks. According to Plutarch (Langhorne's Translation, 1838, p. 490), Alexander built great altars on the banks of the Ganges, on which the native kings were wont to "offer sacrifices in the Grecian manner." Hence, perhaps, the legend of the columns erected by Dionysus.]
