Malay swivel gun
The Lantaka (Baybayin: pre virama: "ᜎᜆᜃ": post virama: "ᜎᜈ᜔ᜆᜃ") also known as rentaka (in Malay, jawi script: رنتاک) was a type of bronze portable cannon or swivel gun, sometimes mounted on merchant vessels and warships in Maritime Southeast Asia. It was commonly equipped by native seafaring vessels from the Philippines, Indonesia, Brunei, and Malaysia. Lela and rentaka are known by the Malays as "meriam kecil" (lit. "small cannon"), the difference is that rentaka is smaller in length and bore than a lela. and Lantakas are often called "Kanyon" in Filipino (literal meaning cannon).
The "lantaka" was cited by the National Commission for Culture and the Arts of the Philippines as an intangible cultural heritage of the country under the 'Traditional Craftsmanship' category that the government may nominate in the UNESCO Intangible Cultural Heritage Lists. The documentation of the craft was aided by ICHCAP of UNESCO.
Etymology.
The name may stem from the Malay word "lantak", which means "hammering down" or "ramming down", referencing its loading process (muzzle-loading). Ramrod in Malay is called "pelantak". The Malay word "rentak" means "stamping the feet in anger", "pounding the feet together".
Description.
The lantaka is the "younger sibling" of the lela; they are smaller, with a length of less than 100 cm. Typically, the bore diameters of these cannons were in the range of about 10–50 mm. Many of these guns were mounted on swivels (called "cagak" in Malay) and were known as swivel guns. The smaller ones could be mounted almost anywhere including in the rigging. Medium-sized cannons were frequently used in reinforced sockets on the vessel's rails and were sometimes referred to as rail guns. The heaviest swivel guns were mounted on modified gun carriages to make them more portable.
History.
The origin of gunpowder-based weaponry in the Nusantara archipelago can be traced from the late 13th century. The Mongol invasion of Java brought gunpowder technology to Java in the form of a cannon (Chinese: 炮—"Pào"). This resulted in eastern-style cetbang which is similar to Chinese cannon. Swivel guns, however only developed in the archipelago because of the close maritime relations of the Nusantara archipelago with the territory of west India after 1460 CE, which brought new types of gunpowder weapons to the archipelago, likely through Arab intermediaries. This weapon seems to be cannon and gun of Ottoman tradition, for example the prangi, which is a breech-loading swivel gun. A new type of cetbang, called the western-style cetbang, was derived from the Turkish prangi. Just like prangi, this cetbang is a breech-loading swivel gun made of bronze or iron, firing single rounds or scatter shots (a large number of small bullets).
In Malaya.
When the Portuguese first came to the Malacca Sultanate, they found a large colony of Javanese merchants under their own headmen; they were manufacturing their own cannon, which is deemed as important as sails in a ship.
Most lantakas were made of bronze and the earliest ones were breechloaders. Michael Charney (2004) pointed out that early Malay swivel guns were breech-loaded. There is a trend toward muzzle-loading weapons during colonial times. Nevertheless, when Malacca fell to the Portuguese in 1511, both breech-loading and muzzle-loading swivel guns were found and captured by the Portuguese.
De Barros mentions that with the fall of the Malacca Sultanate, Albuquerque captured 3000 out of 8000 artillery. Among those, 2000 were made from brass and the rest from iron, in the style of Portuguese "berço" (breech-loading swivel gun). All of the artillery had its proper complement of carriages which could not be rivaled even by Portugal. Afonso de Albuquerque compared Malaccan gun founders as being on the same level as those of Germany. However, he did not state what ethnicity the Malaccan gun founder was. Duarte Barbosa stated that the arquebus-maker of Malacca was Javanese. The Javanese also manufactured their own cannon in Malacca. Anthony Reid argued that the Javanese handled much of the productive work in Malacca before 1511 and in 17th century Pattani.
Wan Mohd Dasuki Wan Hasbullah explained several facts about the existence of gunpowder weapons in Malacca and other Malay states before the arrival of the Portuguese:
The cannons found in Malacca were of various types: "esmeril" (1/4 to 1/2-pounder swivel gun, probably refers to "cetbang" or "lantaka"), "falconet" (cast bronze swivel gun larger than the "esmeril", 1 to 2-pounder, probably refers to "lela"), medium "saker" (long cannon or "culverin" between a six and a ten-pounder, probably refers to "meriam") and "bombard" (fat, heavy and short cannon). The Malays also have one beautiful large cannon sent by the king of Calicut.
Despite having a lot of artillery and firearms, the weapons of Malacca were mostly and mainly purchased from the Javanese and Gujarati, where the Javanese and Gujarati were the operators of the weapons. In the early 16th century, before the Portuguese arrival, the Malays were a people who lacked firearms. The Malay chronicle, "Sejarah Melayu", mentioned that in 1509 they do not understand “why bullets killed”, indicating their unfamiliarity with using firearms in battle, if not in ceremony. As recorded in "Sejarah Melayu":"Setelah datang ke Melaka, maka bertemu, ditembaknya dengan meriam. Maka segala orang Melaka pun hairan, terkejut mendengar bunyi meriam itu. Katanya, "Bunyi apa ini, seperti guruh ini?". Maka meriam itu pun datanglah mengenai orang Melaka, ada yang putus lehernya, ada yang putus tangannya, ada yang panggal pahanya. Maka bertambahlah hairannya orang Melaka melihat fi'il bedil itu. Katanya: "Apa namanya senjata yang bulat itu maka dengan tajamnya maka ia membunuh?"" ;br ;
After (the Portuguese) coming to Malacca, then met (each other), they shot (the city) with cannon. So all the people of Malacca were surprised, shocked to hear the sound of the cannon. They said, "What is this sound, like thunder?". Then the cannon came about the people of Malacca, some lost their necks, some lost their arms, some lost their thighs. The people of Malacca were even more astonished to see the effect of the gun. They said: "What is this weapon called that is round, yet is sharp enough to kill?" 
"Lendas da India" by Gaspar Correia and "Asia Portuguesa" by Manuel de Faria y Sousa confirmed "Sejarah Melayu"'s account. Both recorded a similar story, although not as spectacular as described in "Sejarah Melayu". The "Epic of Hang Tuah" narrates a Malaccan expedition to the country of Rum (the Ottoman Empire) to buy "bedil" (guns) and large "meriam" (cannons) after their first encounter with the Portuguese in 1509 CE, indicating their shortage of firearms and gunpowder weapons. Malaccan expedition to Rum (Ottoman Turks) to buy cannons never actually happened, it was only mentioned in the fictitious literature "Hikayat Hang Tuah", which in reality based on the sending of a series of Acehnese embassies to the Ottoman Empire in the 16th century.
The Dutch and Portuguese quickly learned that they could trade cannons not only for spices and porcelain, but also for safe passage through pirate-infested waters. Local foundries continued to produce guns, using local patterns and designs from local brass and bronze objects. Stylized crocodiles, dolphins, birds, and dragons were common motifs.
In the Philippines.
The ancient walled city of Cainta located in the opposite banks of the Pasig River, is recorded as a fortified city with bamboo thickets and lantaka guns on its walls witnessed by the Spanish conquistadors on the Siege of Cainta in 1571.
As described in an anonymous 1572 account documented in Volume 3 of Blair and Robertson's compiled translations:
This said village had about a thousand inhabitants, and was surrounded by very tall and very dense bamboo thickets, and fortified with a wall and a few small culverins. The same river as that of Manilla circles around the village and a branch of it passes through the middle dividing it in two sections.
In the walls of old Manila, a gunsmith named Panday Pira established a foundry on the northern bank of the Pasig River. Rajah Sulayman commissioned Panday Pira to cast the cannon that were mounted on the palisades surrounding his kingdom. In 1570, Castilian forces under the command of Martin de Goiti captured Manila and took these artillery pieces as war booty, presenting them to Miguel López de Legazpi, the first Spanish Governor-General of the Philippines.
Local tradition.
If a native vessel was unarmed, it was usually regarded by the local populace as improperly equipped and poorly decorated. Whether farmers, fishermen, or headhunters, the villagers who lived in the longhouses along Borneo's rivers lived in fear of being taken by pirates who used both vessel-mounted and hand-held cannons. Villages and tribesmen that were armed with mounted or handheld cannons had a distinct advantage over those who could only rely on bows and arrows, spears, blowguns and krises (swords).
Land transportation in the 17th and 18th century Java and Borneo was extremely difficult and cannons were fired for virtually all types of signaling. Whether they were fired in celebration of a birth or wedding, or to warn another hilltop fortress or riverbank fishing village of an impending attack, cannons were used to transmit messages telling of urgent or special events. Such events ranged from yellow fever and cholera epidemics to the start or finish of religious holidays such as Ramadan.
Distinguished visitors were ushered into longhouses with great ceremony, accompanied by the firing of the longhouse's cannon, much like today's 21-gun salute. These cannons were a display of the status and wealth of the extended family that controlled the longhouse.
All worked brass, bronze and copper had value and were used as trade items in early Borneo. Cannons were frequently part of the bride price demanded by the family of an exceptionally desirable bride or the dowry paid to the groom.
Many of the small cannons, often called personal cannons or hand cannons, had been received as honors and were kept and passed down in families, but in hard times they also served as a form of currency that could keep the family fed. As a recognized form of currency, cannons could be traded for rice, drums, canoes, tools, weapons, livestock, debts of honor, and even settlement of penalties for crimes ranging from the accidental death of a fellow villager to headhunting against another tribe.
Large cannons had the extra value of being used in both celebratory times and in warfare. The larger and/or more elaborate the cannon, the greater the trade value, and thus the greater the status of the owner.
Many of the finest cannons were given out by the Sultans of Brunei as part of ceremonies (such as birthdays or weddings) of the many princes and princesses of the extended Royal family. Cannons were frequently presented to guests along with awards and titles, and were meant to guarantee the recipients' allegiance to the Sultan. Mortars, cannon, and signal guns of all sizes were typically fired with colorful pyrotechnics on these occasions; the louder and more elaborate, the greater the honor.
Modern era.
In the 1840s England began suppressing piracy and headhunting and Rajah James Brooke (a wealthy Englishman who established the dynasty that ruled Sarawak from 1841 until 1946) distributed numerous Brunei cast hand cannons to guarantee the cooperation and allegiance of the local chiefs. "Lantaka" was used by Moro soldiers in the Moro Rebellion against U.S. troops in the Philippines. They were also used by the Filipinos during the Philippine Revolution, this time copied from European models and cast from church bells. One cannon founder was a Chinese Filipino named Jose Ignacio Pawa, a blacksmith also.
Today these guns can be found on virtually all of the islands of the Pacific Rim, but they are most commonly found in the Muslim areas of Indonesia and Malaysia. The largest collection is in Brunei, where it is now illegal to export them. Even in other countries, a museum export permit is usually required.
These cannons are now highly sought after by collectors, with some of the realized prices exceeding $50,000 USD for a single gun. The more common guns can be bought for under $1,000. Replicas and forgeries of "lantaka" are known to exist in considerable numbers.
Today most of the Christians in Mindanao and the Visayas refer the word "lantaka" to "bamboo cannons" (a noisemaker) or any improvised home-made noisemakers of the same firing mechanism usually made of bamboo tubes (Pula in Meranau or "Lapu"), segmented cans of condensed milk, or PVC pipes. They are usually used during New Year's Day celebrations as noisemakers, or often in medium-scale gang wars. The firing mechanism is the same as of the
