A fantastically rich, vertiginous landscape formed in Impressionist and Fauvist tones, Wayne Thiebaud’s Night River from 1995 memorialises the artist’s deep connection with California’s Sacramento River Delta. His home of several decades, the California country gleans in tranquil light, the winding river flowing through the vast agricultural valleys, situating Thiebaud within the rich lineage of contemporary painters who found their muse in America’s Golden State. A particularly warm and sensual example of his Delta Paintings, a series which he began in the 1990s, the present work captures on an intimate scale the simultaneous familiarity and grandeur of the vast landscape of the artist’s home. Testifying to the significance of the series within the artist’s oeuvre, other examples reside in important museum collects ions including The San Francisco Museum of Art and The Smithsonian American Art Museum.

As in all of Thiebaud’s work, the present work has a unique way of infusing feelings of memory and nostalgia, drawing from Thiebaud’s fond childhood memories of his grandfather’s California farm: “I ploughed, harrowed, dug, and hitched up teams […] and planted and harvested alfalfa, potatoes, corn [...] It was a great way to grow up. These paintings have something to do with the love of that and in some ways the idea of replicating that experience” (Wayne Thiebaud quoted in in Steven A. Nash, Ed., Wayne Thiebaud: A Paintings Retrospective, San Francisco 2000, p. 33). Much like the artist’s paintings of cakes and confections from the 1960s and beyond, the Delta Paintings take on a distinctive hazy quality, like half remembered images from adverts or cinema.

Lucious and melodic, Night River exhibits the full range of brushstroke in Thiebaud’s oeuvre. Describings the breadth of movement in the artist’s work, Adam Gopnik writes, “This range of tempi, this variety of brushstrokes not put entirely at the service of description but intended to create a visible rhythm of its own, this jumpy unevenness in the much more concentrated, chamber-music format of Thiebaud’s own work became one of its most distinctive features” (Adam Gopnik, "An American Painter", in Steven A. Nash, Ed., Wayne Thiebaud: A Paintings Retrospective, San Francisco 2000, p. 50). The present work is rich with thick long strokes, which striate the surface into organised rows of crops, and staccato moments of brushwork, which fill the canvas with leafy vegetation. Demonstrating an exceptional mastery of colour, Thiebaud employs his signature “halation” technique; he juxtaposes warm and cool tones to produce a resounding prismatic synergy that contours and electrifies each form off the surface of the canvas. In Night River, a sweeping and seemingly infinite landscape fills the picture plane like a tapestry, with no horizon to orient a viewer or to comprehend the extent of depth in the picture. With its bird’s-eye view, Night River places the drama of the deep blue light of the night against the unexpected combinations of cool indigo and deep red, deep orange and midnight blue.

The harmonious aura of Night River marks a departure from the impossibly elongated and vertiginous proportions of Thiebaud’s San Francisco cityscapes. As Thiebaud explains, “The idea of taking on the later delta pictures had quite a different idea...The San Francisco pictures being a kind of composite of several different things at once. I thought: I wonder if we can do that with landscapes, in a sense. I'd been going to the Metropolitan, looking at Chinese painting, the way in which that perspective is so different.” (Wayne Thiebaud, quoted in Susan Larsen, “Oral History Interview with Wayne Thiebaud,” transcript, Archives of American Art, Smithsonian Institution, Washington, D.C., May 17, 2001.) His keen attention to light and atmosphere in the present work calls to mind Claude Monet’s Haystacks, as he attempts “to express various seasons, various t.mes s of the day, various vantage points” (the artist cited in: Hilarie M. Sheets, “A Riverscape, From Higher Ground,” The New York t.mes s, 30 September 2010, online). The Delta Paintings take on the storied tradition of American landscape painting, with Night River drawing the viewer’s attention to the man-made taming of the great American terrain, much as Thomas Cole did a century and a half before. In addition to its art historical resonance, Night River conveys a modern sensibility with recognizable California roots. Thiebaud’s demonstrable tension between abstraction, realism and colour calls to mind the evocative Northern California landscapes of David Hockney.

With its invocation of the sublime beauty of the American West, viewers luxuriate in the sensual pleasure of Night River. The sweeping landscape and gleaming river is resplendent in its reflection of colour, not unlike Thiebaud's cake frosting. The river glistens in Thiebaud’s impressionistic sunlight with a blue and violet glow, offering the viewer a patchwork of tantalising colour. Revealing an American master at the height of his abilities, the evocative tableau of Night River epitomises the masterful handling of pigment and idiosyncratic world view which has seen Thiebaud become one of the most renowned painters of the last century.

韋 恩·蒂博（Wayne Thiebaud）於1995年創作的《夜河》以印象派和野獸派風格形成一片極為異想天開、叫人神迷目眩的風景，紀念了蒂博與加州沙加緬度河三角洲的深厚連結。加州的鄉郊是蒂博生活了數十年的故鄉，四處沐浴於和煦的陽光下，蜿蜒的河川流經廣闊的山丘農田，風格反映蒂博繼承了一眾以美國金州風景為靈感的當代畫家之豐富的派別傳統，並成為其中一員。《夜河》這幅作品來自他在1990年代開始創作的《三角洲》系列畫作，也是當中尤為溫暖且綺麗的一幅，畫作在其不張揚的小尺幅中捕捉蒂博家鄉廣闊無際的景貌，感覺既親近熟悉，又顯恢宏壯麗。《三角洲》系列的其他作品獲三藩市藝術博物館和史密森尼學會美國藝術博物館等重要博物館收藏，這點引證著這個系列在蒂博作品中的重要性。

本作貫徹著蒂博所有作品的特色，以一種獨特的方式將回憶和情懷融進畫中，其取材來自蒂博在祖父的加州農場所留下的美好童年回憶：「我犁地、耕耙、挖土和拴起馬匹拉犁耕田〔……〕種植和收割苜蓿草、馬鈴薯、粟米……這種成長經歷很美好。這些畫作都與我很愛惜這段成長回憶有關，而且在某程度也是為了想複製這種體驗而創作的。」（韋恩·蒂博，引述自史蒂芬·A·納殊編著，《韋恩·蒂博：作品回顧》，三藩市，2000年，頁33）與蒂博於1960年代及其後創作的蛋糕和甜點畫作一樣，《三角洲》系列的畫作帶有一種極具特色的朦朧質感，如同看過廣告或電影後在記憶中依稀留下的模糊影像。

《夜河》絢爛而如曲調般優美，畫中展現出各式各樣蒂博筆下的獨有筆觸。蒂博的作品有著極多元的筆觸運用，亞當·高普尼克（Adam Gopnik）在描述這種表現時寫道：「跨度如此寬廣的節奏表現，變化如此多端的筆觸，並不完全以描畫景象為目的，而是為了創造一種此畫作獨有的視覺節奏，這種節拍不平均的跳奏風格置於如室樂般緊密集中的形式中呈現，這成為了蒂博作品極為鮮明的特色之一。」（亞當·高普尼克，〈一位美國畫家〉，史蒂芬·A·納殊編著，《韋恩·蒂博：作品回顧》，三藩市，2000年，頁50）在本作中，豐富的厚塗長筆觸將畫面劃成一行行井然有序的莊稼，而一些分散的點塗筆觸則為畫布添上綠野密林。蒂博運用了其特色的「暈影」技巧（halation），展現出他對色彩的非凡掌控力；他又將暖色調和冷色調並置，創造出加倍強烈的五光十色的效果，讓畫作上的每種形狀的輪廓都完整浮現，顯得鮮亮豔麗。在《夜河》中，一片廣袤且看似無限的風景像花紋掛毯般填滿了畫布的表面，沒有任何的地平線來引導觀者視線，也沒有明顯地透露畫面的景深。在鳥瞰的視角下，《夜河》將晚色下變幻的深藍燈光與對岸的色彩對照，形成冷靛藍對深紅、深橙對午夜藍等效果意想不到的配色組合。

《夜河》所展現的安謐氛圍標誌著蒂博的畫風轉向，他不再停留於其三藩市城際畫中、比例異乎尋常地拉長、看得人有目眩感的風景。蒂博進一步解釋：「後來畫《三角洲》系列時是帶著完全不同的想法……三藩市的作品是同時結合了幾個不同方面的綜合體。我不時都會去逛大都會藝術博物館，看看中國山水畫，而畫中的視角竟是如此不同。我就有個念頭：我想知道是否也可以在風景畫中試驗一下。」（韋恩·蒂博，引述自蘇珊·拉森，〈韋恩·蒂博的口述歷史訪問〉，文字記錄，美國藝術檔案館，史密森尼學會，華盛頓，2001年5月17日。）他在本作中對光線和氛圍的細緻關注讓人不其然想到克勞德．莫奈的《乾草堆》，因為蒂博嘗試「表現不同的季節，一天中不同的時間，不同的觀測角度。」（韋恩·蒂博，引述自希拉蕊·M·席絲，〈從高地遠眺的河景〉，《紐約時報》，2010年9月30日，網上文章）《三角洲》系列畫作繼承了美國風景畫膾炙人口的傳統，而《夜河》則尤其讓觀者看見美國的荒野大地是如何馴服於人類的藝術手段下，也即是托馬斯·科爾（Thomas Cole）在一百五十年前所做的事。《夜河》除了與藝術史互相呼應外，還流露出一種很現代的美學感應，而且與加州的淵源也顯然易見。蒂博的作品在抽象表現、現實主義和燦爛色彩之間所展現的牽引和張力也展現於大衛·霍克尼作品中讓人浮想聯翩的北加州風光。

《夜河》喚起美國西部的遺世之美，其五彩斑斕的悅目畫面更讓觀者徹底沉醉其中。延綿無盡的風景和微光閃閃的河流在色彩的映射下光輝燦爛，與蒂博的蛋糕糖霜畫不無異曲同工之妙。河流在蒂博如印象派的筆法下微微閃耀著陽光，透出微藍帶紫的光芒，在觀者眼前拼湊出極其迷人的色彩。蒂博對顏料的精湛運用和異色的世界觀使他成為上世紀最聲名顯赫的畫家之一，《夜河》發人遐想的畫面也是體現這兩點精髓的代表之作，揭示出這位美國大師的巔峰畫技。
