Note 1409 — Chapter II
W. (William) Falconer translation
The Garonne becomes navigable at Cazères near to Rieux, in the ancient Comté de Comminges. From this point to its mouth, following the sinuosities of the river, there are about 68 leagues of 20 to a degree, or 2030 Olympic stadia. The Loire is navigable as far as St. Rambert, about three leagues from St. Etienne-en-Forez, that is to say, double the distance assigned by Strabo. 2000 stadia measured from the mouth of the Loire would extend merely as far as Orleans.
