CHAP. 79.—HISTORICAL FACTS CONNECTED WITH THE DURABILITY
OF WOOD.
Of all the woods, the ebony, the cypress, and the cedar are
considered to be the most durable, a good proof of which is to
be seen in the timber of which the Temple of Diana at Ephesus
is built: it being now four hundred years since it was erected,
at the joint expense of the whole of Asia;
1 and, what is a well-known fact, the roof is wholly constructed of planks of cedar.
As to the statue of the goddess, there is some doubt of what
wood it is made; all the writers say that it is ebony, with the
exception of Mucianus, who was three times consul, one of
the very latest among the writers that have seen it; he declares that it is made of the wood of the vine, and that it has
never been changed all the seven times that the temple has
been rebuilt. He says, too, that it was Endæus who made
choice of this wood, and even goes so far as to mention the
artist's name, a thing that really surprises me very much, seeing that he attributes to it an antiquity that dates before the
times of Father Liber, and of Minerva even. He states, also,
that, by the aid of numerous apertures, it is soaked with
nard, in order that the moist nature of that drug may preserve
the wood and keep the seams
2 close together: I am rather
surprised, however, that there should be any seams in the
statue, considering the very moderate size it is. He informs
us, also, that the doors are made of cypress, and that the
wood, which has now lasted very nearly four hundred years,
has all the appearance of new.
3 It is worthy of remark, too,
that the wood of these doors, after the pieces had been glued
together, was left to season four years before they were put
up: cypress was made choice of from the circumstance that it
is the only kind of wood that maintains its polish to all future
time.
And have we not the statue of Vejovis,
4 also, made of cypress,
still preserved in the Capitol, where it was consecrated in the
year of the City 661? The Temple of Apollo, too, at Utica,
is equally celebrated: there we may see beams of cedar still
in existence, and in just the same condition in which they
were when erected at the first building of that city, eleven
hundred and seventy-eight years ago. At Saguntum, too, in
Spain, there is a temple of Diana, which was brought thither
by the original founders of the place, from the island of Zacynthus, in the year 200 before the taking of Troy, Bocchus
says—It is preserved beneath the town, they say. Hannibal,
being induced thereto by feelings of religious veneration,
spared this temple, and its beams, made of juniper, are still
in existence at this very day. But the most memorable instance of all is that of the temple which was dedicated to the
same goddess at Aulis, several ages before the Trojan War: of
what wood, however, it was originally built is a fact that has
been long lost in oblivion. Speaking in general terms, we
may say that those woods are of the greatest durability which
are the most odoriferous.
5
Next to those woods of which we have just spoken, that of
the mulberry is held in the highest degree of esteem, and it
will even turn black when old. There are some trees, again,
that are more durable than others, when employed for certain
purposes. The wood of the elm lasts the best in the open air,
that of the robur when buried in the ground, and that of the
quercus when exposed to the action of water: indeed, the
wood of this last, if employed in works above ground, is apt
to split and warp. The wood of the larch thrives best in the
midst of moisture; the same is the case, too, with that of the
black alder. The wood of the robur spoils by exposure to the
action of sea-water. The beech and the walnut are far from
disapproved of for constructions under water, and, in fact,
these are the principal woods, too, that are used for works
under ground: the same is the case, also, with the juniper;
which is equally serviceable when exposed to the atmosphere.
The woods of the beech and the cirrus
6 very quickly deteriorate, and that of the æsculus will not withstand the action
of water. On the other hand, the alder, when driven into the
ground in marshy localities, is of everlasting duration, and
able to support the very heaviest weights. The wood of the
cherry is strong, while those of the elm and the ash are pliable, though apt to warp: these last will still retain their
flexibility, and be less liable to warp, if the wood is left to
stand and dry upon the trunk after the pith has been cut
around.
7 It is said that the larch, when used for sea-going
ships, is liable to the attacks
8 of the teredo, as, in fact, all the
woods are, with the exception of the wild and cultivated olive.
It is a fact, too, that there are some woods that are more liable
to spoil in the sea, and others in the ground.
