De fago

De fago. 

Fagus, ut dicit Ysidorus, arbor est glandifera, cuius fructus dulcis est, sed nocivus pectori. Oleum vero clarissimum lampadibus amministrat. Satis admodum durum, sed vermibus penetrabile lignum eius, nisi fumo pene sit continue delibutum. Dicitur autem fagus a comestione: fage enim comedere dicitur. [Hoc lignum viride per longa tempora in aquis positum in lapidem durescere dicitur.]

Of the beech tree,

 

The beech tree, as Isidore says, is an acorn-bearing tree, the fruit of it is sweet, but it is harmful to the chest. Truly it administers the clearest oil for lamps. The wood of it is sufficiently fully hard, but is penetrable by worms, unless almost continually steeped with smoke. It is however called “beech” from “consuming”: for “fage” in fact means “to eat”. This green wood is said to harden into stone when placed for long periods in water.

Ysidorus: Isidore of Seville. Wrote the Etymologies which included sections upon various types of trees. 

Dicitur autem… comedere dicitur: Isidore wrote that the Latin fagus came from the Greek φαγεĩν, meaning “to eat,” as the acorns born by the tree were consumed by the Romans. There is not a proven connection between the two words.
