五種古舊顏料的多彩故事

The colors of art change not just with trends， but availability as well. For reasons of being incredibly toxic3）， expensive， or just involving way too many snails， here are five pigments that have disappeared from art.

藝術(shù)作品的用色不僅會(huì)隨著時(shí)尚潮流而改變，也會(huì)因是否有可用的顏料而改變。由于有劇毒或是過(guò)于昂貴，抑或僅僅是因?yàn)樵谥谱鬟^(guò)程中需要使用太多蝸牛，以下這五種顏料已經(jīng)從藝術(shù)作品中絕跡了。

On murals4）， pottery， even possibly painted on the unlucky bodies offered as human sacrifices， a sky-blue color has been found in artifacts of the Maya and Aztec5）. It disappeared around colonial times in Central America， just like the pre-Columbian civilizations themselves. Known as Maya Blue， it's long been recognized as a mix of a natural clay and a dye from the indigo6） plant. But how it was so durable in not being subject to fading or even the deterioration of solvents7） and acids has been a mystery. Earlier in 2013， however， some chemists announced they may have found the secret.

The most prized pigment of the ancient world was actually made from a predatory9） snail. Tyrian Purple got its name from the best of the marine shellfish used to make the pigment being found off the shore of Tyre， according to Pigment Compendium10）. Not only was it a properly11） royal color of rich， slightly red purple， it was said to get even more beautiful and brighter when exposed to the sun and the elements12）. Yet since you needed a whole pile of snails to make it， it was very expensive， and eventually disappeared.

在瑪雅人和阿茲特克人的古器物上可以看到一種天藍(lán)色，比如在壁畫(huà)和陶器上，甚至可能連用作人祭的那些可憐人的身體上也涂著這種顏色。和前哥倫布時(shí)期的那些美洲文明一樣，大約在殖民時(shí)期，這種顏色也從中美洲消失了。這種被稱(chēng)為“瑪雅藍(lán)”的顏料長(zhǎng)期以來(lái)一直被認(rèn)為是用天然黏土和從槐藍(lán)屬植物中提取的染料混合而成的，但是它為什么如此耐久（既不容易褪色，甚至也不容易被溶劑和酸腐蝕）則一直是個(gè)謎。不過(guò)在2013年初，幾位化學(xué)家宣稱(chēng)他們可能已經(jīng)發(fā)現(xiàn)了其中的秘密。

這種古代世界最為珍貴的顏料其實(shí)是用一種肉食性蝸牛制作而成的。據(jù)《顏料手冊(cè)》記載，推羅紫得名于一種上佳的海貝，它曾是制作這種顏料的原料，在推羅沿岸的海里可以覓得其蹤影。這種紫中稍微透點(diǎn)紅的濃郁色彩不僅非常高貴，而且據(jù)說(shuō)在經(jīng)過(guò)風(fēng)吹日曬之后會(huì)變得更加美麗鮮艷。不過(guò)，制作這種顏料需要使用成堆的蝸牛，因此它十分昂貴，最后就消失了。

The luminosity13） of classical European oil paintings was due in large part to White Lead， a pigment of lead carbonate14） and sulfate15）. Artists like Vermeer used it to create a special kind of light that radiated16） from the canvas， the traces of which we can see in its grainy17） texture. Unfortunately， its striking brightness was rather poisonous. Yet as Applied Polymer18） Science explains about the lead paint： "Toxicity was recognized， but accepted." It's since been largely replaced by Titanium19） White， a less harmful pigment， yet some artists still seek out the White Lead for its superior color and permanence， even if it is more difficult to find and still toxic.

歐洲古典油畫(huà)作品的那種光亮感在很大程度上都要?dú)w功于鉛白——一種由碳酸鉛和硫酸鹽制成的顏料。諸如維米爾（編注：荷蘭著名畫(huà)家）之類(lèi)的畫(huà)家利用這種顏料創(chuàng)作出了一種從畫(huà)布中發(fā)出的特殊亮光，我們可以從顏料粗糙的質(zhì)感中看到這種亮光的痕跡。遺憾的是，這種異常明亮的顏料毒性相當(dāng)大。不過(guò)，這種含鉛的顏料正如《應(yīng)用聚合物科學(xué)雜志》介紹的那樣：“當(dāng)時(shí)人們明知它有毒，但還是要用它?！焙髞?lái)，鉛白顏料基本上被毒性較小的鈦白顏料所取代了，但有些畫(huà)家為了追求它那出眾的色彩和永不褪色的效果，仍然在尋找鉛白來(lái)作畫(huà)，盡管它比從前更難尋覓，而且毒性依舊。

Widely believed to be the most expensive pigment ever created， more expensive than even its weight in gold， the Lapis Lazuli pigment was made from grinding up Lapis Lazuli semi-precious stones. Its use goes back to the 6th century in Afghanistan， but its popularity really took off with wealthy Renaissance patrons21） who wanted the stunning blue on the robes of Mary and Jesus in religious paintings. The color largely disappeared as it was so incredibly expensive and required quarries22） to collect the stones.

用磨碎的天青石（一種半寶石）制作的天青石顏料被普遍認(rèn)為是有史以來(lái)最為昂貴的顏料，甚至比同等重量的黃金還要貴重。這種顏料的使用歷史可以追溯到公元6世紀(jì)的阿富汗，但是直到文藝復(fù)興時(shí)期，隨著那些富有的藝術(shù)贊助人希望用這種美輪美奐的藍(lán)色為宗教畫(huà)上的圣母瑪利亞和耶穌的長(zhǎng)袍著色，它才真正流行起來(lái)。由于這種顏料實(shí)在貴得出奇，而且只有在采石場(chǎng)才能開(kāi)采到天青石，因此它已經(jīng)基本絕跡了。

The pigment known as Dragon's Blood had the most epic and ridiculous of origin stories， a legendary mix of actual dragon's blood and elephant's blood during the battles between them. The pigment was in actuality made from a Southeast Asian tree—though the story certainly helped hype23） it to outside buyers， and its blood red color was popular in the ancient world. It faded out of mainstream popularity around the 19th century， probably alongside the very much waning24） story with elephant vs. dragon battles.

這種顏料號(hào)稱(chēng)“龍血”，關(guān)于其來(lái)源有著最為傳奇和荒誕的傳說(shuō)，據(jù)說(shuō)它是在龍象交戰(zhàn)時(shí)由龍和象的血液交融而成的。但實(shí)際上這種顏料是從東南亞的一種樹(shù)木中提取出來(lái)的，不過(guò)這個(gè)傳說(shuō)的確幫助它在外來(lái)的客商中打響了知名度，它那血紅的顏色在古代很受歡迎。大約在19世紀(jì)，它逐漸不再受到主流社會(huì)的歡迎，恐怕這與龍象大戰(zhàn)的故事影響力減弱有關(guān)。
