Moral Letters to Lucilius Section 3

In Lycia regio notissima est, Hephaestion incolae vocant, foratum pluribus locis solum, quod sine ullo nascentium damno ignis innoxius circumit. Laeta itaque regio est et herbida nihil flammis adurentibus, sed tantum vi remissa ac languida refulgentibus.

Il y a en Lycie une contrée bien connue, que les habitants nomment Héphestion : c’est un sol percé en plusieurs endroits et entouré d’une ceinture de feux inoffensifs qui n’endommagent nullement ses productions : pays fertile, couvert d’herbages, où rien ne souffre de cette flamme amortie et languissante comme la lueur qu’elle donne.

There is a well-known place in Lycia - called by the inhabitants “Hephaestion” - where the ground is full of holes in many places and is surrounded by a harmless fire, which does no injury to the plants that grow there. Hence the place is fertile and luxuriant with growth, because the flames do not scorch but merely shine with a force that is mild and feeble.
