One of the many ethnological vignettes in Alfred Russel Wallace’s The Malay Archipelago (1869):
Macassar is the most celebrated place in the East for “running a muck.” There are said to be one or two a month on the average, and five, ten, or twenty persons are sometimes killed or wounded at one of them. It is the national, and therefore the honourable, mode of committing suicide among the natives of Celebes, and is the fashionable way of escaping from their difficulties. A Roman fell upon his sword, a Japanese rips up his stomach, and an Englishman blows out his brains with a pistol. The Bugis mode has many advantages to one suicidally inclined. A man thinks himself wronged by society–he is in debt and cannot pay–he is taken for a slave or has gambled away his wife or child into slavery–he sees no way of recovering what he has lost, and becomes desperate. He will not put up with such cruel wrongs, but will be revenged on mankind and die like a hero. He grasps his kris-handle, and the next moment draws out the weapon and stabs a man to the heart. He runs on, with bloody kris in his hand, stabbing at everyone he meets. “Amok! amok!” then resounds through the streets. Spears, krisses, knives, and guns are brought out against him. He rushes madly forward, kills all he can–men, women, and children–and dies overwhelmed by numbers amid all the excitement of a battle. And what that excitement is those who have been in one best know, but all who have ever given way to violent passions, or even indulged in violent and exciting exercises, may form a very good idea.
