![]() ![]() His song continues to resonate today, a testament to the enduring appeal of this bewitching brown bird. Its enchanting song has made it a powerful symbol of love, beauty, and the power of art. In John Keats’ famous poem, “Ode to a Nightingale,” the bird’s enchanting song transports the poet to a world of transcendent beauty, providing a temporary escape from the suffering and impermanence of human life.įrom ancient Greece to Chinese folklore, the nightingale has captured the imagination for thousands of years. The poem focuses on a speaker standing in a dark forest, listening to the beguiling and. At 80 lines, it is the longest of Keatss odes (which include poems like 'Ode on a Grecian Urn' and 'Ode on Melancholy'). From the Middle Ages to the Romantic era, the bird was often portrayed as a symbol of love, beauty, and poetic inspiration. 'Ode to a Nightingale' was written by the Romantic poet John Keats in the spring of 1819. The nightingale’s allure has not gone unnoticed in European literature. In appreciation, the grateful people declared the nightingale their protector and a symbol of hope, demonstrating the bird’s ability to inspire and heal through its voice. One famous tale tells of a nightingale that used its song to save a kingdom from destruction. In Chinese folklore the nightingale symbolises happiness, virtue, and the power of music. This metaphorical relationship between the nightingale and the rose is a recurring theme in Persian poetry, highlighting the pursuit of spiritual enlightenment and love. The bird’s passionate song is often directed towards the rose, symbolising both earthly beauty and the divine beloved. In his poems, the nightingale frequently represents a spiritual seeker, yearning for union with the divine. In Persian literature the nightingale holds a prominent place, most notably in the poetic works of the great poet Hafez. ![]() The bird’s nocturnal song was thought to inspire lovers and to provide comfort during the hours of darkness. In Roman culture the nightingale was associated with the goddess Venus, symbolising love, passion, and the renewal of life in springtime. The nightingale thus became a symbol of transformation, resilience, and the power of art to heal and communicate. Through her metamorphosis, Philomela found her voice again, expressing her pain and sorrow through song. In ancient Greece the bird was often linked to the tragic tale of Philomela, a princess who was transformed into a nightingale after a horrific act of violence. The nightingale’s association with Greek and Roman mythology is well-documented. In this blog post we’ll explore the nightingale’s place in cultural history, and how different cultures around the world have ascribed their own symbolism to this captivating avian. Its melodious voice and nocturnal habits have made it an enduring symbol of love, beauty, and transcendence. I am aware that I have many conflicting interpretations here, but that is the beauty of the song, it is so rich and multi-layered.30 March, 2023 The nightingale, a small bird renowned for its enchanting song, has captured the hearts and imaginations of countless people throughout history. I am aware that I have many conflicting interpretations here, but that is the beauty of the song, it is so rich and multi-layered. Memories of his love provide no real comfort - "All your songs of beauty fail". However I feel that Cohen is mourning the loss of his love who has died,whose once beautiful songs fail to comfort even him as he grieves, such is the intesnity of his love and greif. ![]() He is unable to access this and it leaves him feeling detached. His nightingale may have left him for another man - "I lived but to be near you, Though you are singing somewhere still, I can no longer hear you" - she may be singing, in other words sharing the gift of her love, with someone else. It could be that Cohen, once optimistic in his youth -"Love was all beginning" may have become disillusioned and even cynical about life as he grew older, but retains a faint note of hope that the goodness in life still exists somewhere - "Though you are singing somewhere still, I can no longer hear you". Or perhaps Cohen is saying that all good things must come to an end? "Now all your songs of beauty fail" - also suggesting a kind of disillusionment with romantic love as a whole. "Rest in peace.beneath your branch of holly" obviously describes the wreath placed on her grave, but the holly may be deliberate as it is an evergreen plant, symbolising the unending nature of his love. Or perhaps "I built my house beside the woods so I could hear you singing" shows that true love is found in nautre the world around him in all its beauty and wildness inspires greater love than any earthly being will.Ī family member also suggested this song may be about suicide - "The forest closes round you". "I built my house beside the woods, So I could hear you singing" suggests that he went out of his way to access this love, perhaps the woods are a symbol that he isolated himself for the sake of love? The symbolism of the nightingale is obvious the nightingale is the bird of love. ![]() ![]() ![]() ![]() Speaking of Woo Tak, he endears himself to us even more (did we even think that was possible?) in the finale when he forfeits his job as a police officer rather than perjure as a witness, and then reveals just how alone in the world he is, with parents that wouldn’t even care if they learned of his sacrifice. Remember all that talk in the first few episodes about time flowing like water, and the mystery of what would come of the characters altering the flow of time?Īre we meant to think that Choi’s death by car crash is time’s way of making up for the fact that they saved Woo Tak from dying via car crash at the very beginning? Does this mean that somehow the direction to which they redirected time has taken root, and our main trio will no longer face constant mortal peril? It would be nice if the drama offered a clear explanation of this, instead of leaving us scrambling to fill in the gaps. Investigator Choi’s death also makes us wonder if this is the drama’s way, however ambiguous, of resolving some questions that it posed and then largely ignored. Jae Chan talking to a dying Investigator Choi in the present, knowing that the Choi of 13 years ago is/was listening to his words in a dream and has/will live with them in his heart for so many years – and still make the same choices that will ultimately lead to his death, just to watch over Jae Chan – gives a new level of poignancy to the entire arc of the drama. The death of Choi Dam Dong ( Kim Won Hae), so shortly after the revelation that he was the police officer that Hong Joo and Jae Chan saved when they were children, was heart-wrenching in the best of ways. “While You Were Sleeping” really finished strong with its bittersweet yet feel-good finale. ![]() Warning: the remainder of the review contains spoilers for Episodes 13-16 What we got was a lot more straightforward, but also more focused on the comedy and the relationships, which I’m not complaining about, because it helped furnish the characters with so many layers, both in the present and in their shared past. In general, this was one of the biggest disappointments in “While You Were Sleeping” – it bestows its characters with this remarkable and interesting power… but then does little to explore the how and why of this power. To break up this pattern, the drama might have benefitted from delving further into the dream abilities. But because this cycle became so familiar, each hazard that the characters faced felt less urgent, so that by the time the drama reached Hong Joo’s big scene with the green umbrella, the situation had lost much of its gravity because we were so used to Jae Chan, Hong Joo, and Woo Tak bailing each other out. Perhaps it’s inevitable that a show in which the characters can see the future is bound to be predictable. ![]() The criminals that Yoo Beom defends are more standard villains, and the drama became a bit repetitive when it cycled through one of these bad guys after another, falling into a familiar pattern of our characters dealing with the latest case, dreaming about some related danger, and then saving each other from this danger. The Three Flying Dragons, on the other hand, choose to always diligently to stick to what they know to be right, at times even putting their careers at risk, in their desire to do good. But he’s a good foil for our main characters, and through this contrast the drama shows how the choices people make impact those around them. Self-centered Yoo Beom never cares about how his decisions affect others, and ends up having to lie and fabricate, digging himself a hole that eventually becomes way too deep to climb out of. Yoo Beom is admittedly confusing as a villain it would be a stretch to say he’s full-blown evil, because we do see signs of his self-loathing for defending some truly vile people. Little details can make drama characters come to life, and it’s a credit to the show’s writers that “While You Were Sleeping” is rife with these humanizing elements, like Lee Yoo Beom’s ( Lee Sang Yeob) nervous habit of rolling up bits of paper when he’s thinking. And while none of the characters presented particularly challenging roles to play, the actors were well-suited to their parts in a way that really made them shine. Each and every character added an extra dimension to the drama that made the storyline that much richer. ![]() ![]() Any bird flying around your area will surely notice your feeding stations and visit it.Ĥ.

![]() ![]() Tuhiwai Smith describes this as "research through imperial eyes". Their stories became accepted as universal truths, marginalising the stories of the Other. Tuhiwai Smith draws on Edward Said's Orientalism to describe how travellers' and observers' representations (formal and informal) of indigenous peoples were encoded as the authoritative representation of the Other, thereby framing the wider discourse and attitudes towards indigenous peoples. ![]() ![]() Under this Western paradigm, colonisers, adventurers and travellers researched the indigenous Other through their "objective" and "neutral" gaze. She deconstructs the assumptions, motivations and values that inform Western research practices (the methodologies, the theories and the writing styles) through exploring the Enlightenment and Positivist traditions in which Western research is viewed as a scientific, "objective" process. In the first part of the book, Tuhiwai Smith adopts a feminist and critical theory framework. The second part focuses on setting a new agenda for indigenous research. The first part discusses the history of Western research and critiques the cultural assumptions behind research by the dominant colonial culture. Tuhiwai Smith's book is divided into two parts. However, this review is not intended to negate the views and perspectives of indigenous peoples and offer the "real" review, but rather to offer another reading of Tuhiwai Smith's book from the perspective of a non-indigenous researcher. A review that focuses specifically on whether this book is useful for a non-indigenous researcher could be read as continuing to (re)inscribe a Western "ethnocentric" view: that any work by indigenous peoples can only be identified as "legitimate" and "real" knowledge if it fits within a Western framework and has value for the dominant non-indigenous culture. ![]() An important audience for the book would be indigenous academics and researchers who may be developing indigenous research agendas, methodologies and protocols. In a sense this review has a very "ethnocentric" focus. In particular, what a non-indigenous researcher needs to be aware of when researching with indigenous peoples how non-indigenous researchers can improve their practices with indigenous peoples and, most fundamentally, whether it is appropriate for non-indigenous researchers to be involved in research with indigenous peoples. This review focuses on how Tuhiwai Smith's book can inform non-indigenous researchers who may be involved in research initiatives with indigenous communities. According to Tuhiwai Smith, "decolonization" is concerned with having "a more critical understanding of the underlying assumptions, motivations and values that inform research practices". Tuhiwai Smith's book challenges traditional Western ways of knowing and researching and calls for the "decolonization" of methodologies, and for a new agenda of indigenous research. This line, from the introduction to Linda Tuhiwai Smith's book Decolonizing Methodologies, sets the scene for an extensive critique of Western paradigms of research and knowledge from the position of an indigenous and "colonised" Maori woman. "Research" is probably one of the dirtiest words in the indigenous world's vocabulary.
