the date palm.
So far as is known, the ancients, though they made extensive use of fibre rope,
were apparently not much acquainted with wire ropes, which are, of course, an essential
feature in modern rope haulage. It is certain that the Assyrians practised the art of
beating metal into wire, but there is no evidence to show whether or not they twisted
it into ropes. It is said that the Chinese not only knew of, but actually used wire ropes
1,500 years ago, in the form of short ropeways for crossing rivers. The method is shown
in Fig. 344. A fine specimen of bronze rope was found in the buried city of Pompeii
and is now preserved in the Museo Borbonico at Naples. Unfortunately no information
seems to be available as to the purpose to which this wire rope was applied, but its
discovery in buried Pompeii is significant in view of the very modern date that has been
claimed for the introduction of wire ropes.
