I've been reading Mark Wiley's Arnis: Reflections on the History and Development of the Filipino Martial Arts (say that 3 times fast).
The book ia a collection of essays and articles dealing with the FMA. The first part of the book deals with the origins of eskrima and arnis.
The second essay I found particularly interesting. It was written by a Dr. Ned Nepangue and it basically questions the theory that eskrima and arnis descended from an earlier system called kali. In the essay, the author states known objective facts and offers his opinions on them, relating to the connection of eskrima and arnis to kali. I'll just list his listed facts to open up a discussion on them. For his opinions and conclusions, get the book
There was no 'Fact 7' in the book, apparently a misprint or some other mistake. The listed facts containing geographic and/or anthropologic material are beyond me, since I'm not very familiar with the Philippines. I find Fact 13 to be particularly interesting, and I'll try to see if I can scare up any info on this garrote larense.

All quoted material is authored by Dr. Ned Nepangue and has not been altered from its presentation given in Wiley's book, the title of which is at the top of this post. Any spelling errors are my own.

Fact 1
There are no available written records that describe what the allegedly pre-Hispanic martial art of kali really was, nor is there evidence to prove that eskrima is even related to "the art of kali".
Fact 2
Research indicates that the natives in the Philippines before the arrival of the Europeans used shields and spears, weapons that are no longer visible in the majority of the contemporary eskrima schools.
Fact 3
The claims that historical personalities such as Lapulapu, Tupas, and others practiced kali or eskrima remain unproven.
Fact 4
All eskrima systems share more common traits than differences.
Fact 5
Practically all eskrima systems are practiced only in the Christianized groups (or those who were under the direct influence of the Spanish conquistadors for 333 years). Moreover, no known eskrima system is found among the peoples in the hinterlands of Luzon, among the Lumad, or the Muslims in Mindanao.
Fact 6
While many posit that eskrima comes from kali, and kali from silat, the link between kali and silat is yet to be proven. In fact, both arts are quite different in form and substance.
Fact 8
About 65 percent of technical terms used in all eskrima systems, although developed and propagated by many linguistically diverse ethnic groups, are of Spanish origin.
Fact 9
The connection between kali and the Indonesian martial art of tjakalele (its supposed predecessor) is not yet proven.
Fact 10
The suggestion that kali is the root word of some terms found in different Filipino languages and dialects is not based on linguistics. In fact, a study of this claim has yet to be made.
Fact 11
The earliest technical description of eskrima has become available only lately. In fact, the first known book available to the public was Placido Yambao's Mga Karunungan sa Larong Arnis, published in 1957. Thus, there are no truly historical documents on the history of these arts.
Fact 12
Many fighting modalities in eskrima, such as espada y daga (sword and dagger), are also found in European fencing arts.
Fact 13
The once-Spanish colony of Venezuela in faraway South America also has its own form of stick fighting, known as garrote larense. This Venezuelan art reminds one of eskrima. There must be a connection between these two martial arts somewhere, and further research is needed.
Fact 14
It is without basis to say that eskrima is just a phase of natural evolution of kali--that is, kali being the original form, while eskrima is the modern and diluted equivalent.
Fact 15
The proposed theories on the origins of eskrima are actually not corroborated in the works of the experts on Philippine history, anthropology, and sociology.
There was no 'Fact 7' in the book, apparently a misprint or some other mistake. The listed facts containing geographic and/or anthropologic material are beyond me, since I'm not very familiar with the Philippines. I find Fact 13 to be particularly interesting, and I'll try to see if I can scare up any info on this garrote larense.
