Indonesian spear with brass blade

[A. G. Maisey]

I tend to disagree that that this is a matter for any kind of argument, but it is a matter which needs to be understood and which deserves to have statements that deal with the characteristics of these two materials expressed in specific terms.

When we are specific there can be no argument, because in the presence of clear evidence there can be no variation in opinion.

EDIT

I've just noticed, that last google link is to van Heekeren, I did not know this book was online, its worth a read.
