Mythlok Perspective

In Mythlok’s Perspective, Bakunawa represents humanity’s ancient fear of losing the natural order. Like Fenrir in Norse mythology, whose actions threaten cosmic stability, or Rahu in Indian mythology, who swallows the sun or moon during eclipses, Bakunawa transforms celestial darkness into a struggle between chaos and restoration. Yet Bakunawa’s legend carries a distinctly communal dimension, as people unite through noise and ritual to protect the remaining moon. Where Fenrir embodies an approaching cosmic catastrophe and Rahu reflects the cyclical tension between celestial forces, Bakunawa reveals how collective action becomes a response to the incomprehensible.

Bakunawa

Introduction

Bakunawa is a legendary serpent or dragon in Philippine folklore, best known for its association with lunar eclipses. Particularly prominent in Visayan traditions, this formidable creature is believed to emerge from the depths of the sea to swallow the moon, plunging the night sky into darkness. The legend offers a traditional explanation for an extraordinary celestial event, connecting the movements of the heavens with the powerful beings believed to inhabit the natural world.

One of the best-known accounts of Bakunawa appears in Bakunawa and the Seven Moons, a narrative recorded by Cebuano writer Fernando A. Buyser in 1913. In this story, the sky once had seven moons, but Bakunawa swallowed six of them before attempting to consume the last. The tale reflects the enduring place of oral storytelling in Philippine culture, where celestial phenomena became part of narratives about supernatural creatures, divine forces and human responses to the unknown.

Physical Traits

Bakunawa is generally described as an enormous serpent or dragon associated with the sea and the night sky. Its defining characteristic is its ability to swallow the moon, making its immense size and fearsome mouth central to its identity. The creature’s serpentine form connects it to the ocean’s depths, while its ability to reach the heavens gives it a place in stories that bridge the earthly and celestial realms.

Descriptions of Bakunawa vary across retellings and artistic interpretations. Some modern depictions portray it with elaborate dragon-like features, dramatic scales or other supernatural characteristics. These visual representations contribute to its striking appearance in contemporary art, although such details should not be treated as universal features of the traditional legend. At the heart of the mythology, Bakunawa remains a powerful moon-swallowing serpent whose appearance reinforces its extraordinary role in explaining eclipses.

Family

Bakunawa’s family relationships are not consistently established in surviving accounts of Philippine folklore. Rather than having a clearly documented genealogy, the creature is primarily remembered through stories about its attempts to swallow the moon and the efforts made to prevent it from plunging the world into darkness.

In Fernando A. Buyser’s Bakunawa and the Seven Moons, the narrative includes Bathala, a prominent divine figure, in the wider story of the moons and the serpent. The account provides a connection between Bakunawa and the divine realm, but it does not establish a detailed family tree involving parents, siblings, a mate or offspring. Different retellings may develop the relationships between supernatural beings in their own ways, making it important to distinguish individual narrative versions from a shared mythological tradition.

Other names

Bakunawa appears under variant spellings in historical and regional sources. One historically documented form is Bacunaua, recorded in Alonso de Mentrida’s seventeenth-century Hiligaynon dictionary in connection with a serpent believed to swallow the moon. The spelling Bakonawa also appears in discussions of the legend, illustrating how names can vary across historical records and linguistic traditions.

The precise origin of the name remains a subject for cautious interpretation. Some scholarly discussions connect it with sawa, a term for a python, alongside a proposed interpretation involving a curved or bent serpent. The name should not be assigned a definitive linguistic origin without stronger evidence. Likewise, alternative names sometimes circulated in modern accounts require individual verification before they can be confidently attributed to particular Philippine communities. These variations reflect the importance of regional languages and oral transmission in preserving folklore across the archipelago.

Powers and Abilities

Bakunawa’s defining supernatural ability is its power to swallow the moon, an act associated with lunar eclipses. In the seven-moons narrative, the creature consumes six moons and subsequently threatens the last one. Its ability to reach a celestial body from the earthly world establishes it as an extraordinary being whose actions can transform the appearance of the night sky.

Traditional eclipse beliefs also describe people making loud noises to drive the creature away. In accounts associated with the Bakunawa legend, communities would bang pots, pans and other objects in an effort to frighten the serpent and restore the moon. This response reflects the belief that human actions could influence the outcome of a supernatural encounter. Related eclipse traditions recorded elsewhere in the Philippines also involve making noise to repel a moon-threatening creature, although the being and details vary between accounts.

Bakunawa’s power lies primarily in its role as a force capable of disrupting the celestial order. Its association with the sea and its ability to consume the moon connect two seemingly distant realms: the ocean below and the heavens above. Although modern interpretations sometimes attribute additional abilities to the creature, such as controlling storms or changing its form, these should be linked to specific stories rather than assumed to be universal characteristics of Bakunawa.

Modern Day Influence

Bakunawa continues to inspire contemporary Philippine literature, visual art and popular culture. Writers and artists reinterpret the moon-eating serpent through new narratives, using its striking imagery to explore themes of identity, transformation, conflict and the relationship between humanity and the natural world. One example is The Last Bakunawa, a contemporary literary work by Allan N. Derain that demonstrates how the legendary creature can inspire new forms of storytelling.

The creature has also become a symbol of creative expression in contemporary cultural events. Bakunawa Fest, a Philippine fantastic-film festival, draws its name from the legendary serpent and connects the creature’s place in folklore with modern filmmaking. Such uses demonstrate how traditional stories can move beyond their original narrative settings and acquire new meanings through contemporary artistic expression.

Bakunawa’s enduring appeal lies in its ability to connect the natural world with the imagination. The legend once offered a traditional explanation for the disappearance of the moon during an eclipse; today, it also provides artists and storytellers with a powerful image drawn from Philippine cultural heritage. Through literature, film and visual reinterpretation, Bakunawa remains a recognisable figure in the country’s folklore, illustrating how traditional narratives can continue to evolve while retaining their cultural significance.

    Il fait penser au Jörmungandr ou Midgardsorm des Norrois. Fils de Loki et de la géante Angrboda, ce serpent est le frère du loup Fenrir qui mange la lune et de Hel, la déesse du monde des morts. Il est possible que dans les croyance Philippines, Bakunawa soit plus proche d’une authenticité mythologique ayant été moins travaillé par des générations de copieur et de mythographes qui se succèdent depuis le IXème siècle.
