Turrell V. Wylie

Written Tibetan is unusually hard to romanise because its spelling preserves a much older pronunciation. A syllable can carry a prefixed letter, a superscribed letter, a subscribed letter and one or two suffixes, most of which are no longer sounded, so the written form and the spoken form diverge sharply and a system based on either one loses the other. The romanisations in use before 1959 dealt with this by adding diacritical marks, which worked on a printed page and failed everywhere else: they could not be typed, could not be filed in a card catalogue, and were dropped or mangled in transmission.

Wylie proposed a scheme that uses only the twenty six letters of the roman alphabet, with an apostrophe standing for one Tibetan character, and that maps the letters one to one. Nothing is added and nothing is inferred, so the transliteration can be turned back into Tibetan script without loss, and two scholars writing the same word will produce the same string. It was adopted quickly and became the standard for English language scholarship, and the property that made it succeed on a typewriter is what has kept it in place through card indexes, databases and keyboards.

The timing mattered as much as the design. The scheme appeared in 1959, the year the Dalai Lama left for India, at the start of the period in which Tibetan studies grew rapidly in Europe and North America and a large body of literature had to be catalogued, cited and taught by people entering the field at once. A standard adopted at the beginning of an expansion becomes very hard to displace later, and this one was adopted at exactly that moment.

The gain is precision. A term written in this scheme can be looked up, sorted, searched and cited without ambiguity, and a reader who knows Tibetan can reconstruct the spelling exactly. The cost is that the result is unreadable to anyone who does not, because the silent letters are all there: the bodhisattva of compassion is written spyan ras gzigs and is pronounced roughly Chenrezig, and no amount of goodwill will get an English reader from one to the other. Scholarship therefore runs two systems in parallel, a strict transliteration for accuracy and a loose phonetic rendering for reading aloud, and while the first is standardised the second is not, so the same name appears in half a dozen spellings across otherwise careful books.

This atlas inherits the problem and handles it the same way, giving a readable form and noting the transliteration where precision matters. Wylie other work, on Tibetan geography and on the relationship between Tibet and the Mongol court, belongs to the ordinary business of a field, and it is the two page article that turned out to be the durable contribution, which is a common enough pattern and worth recording without irony.

There is a further consequence for anyone searching a reference work. Because the strict form and the readable form share almost no letters at the start of a word, a reader who knows a name in one cannot find it in the other, and an index built on only one of them is unusable to half its audience. That is a practical reason for a reference work to record both, and it is why an atlas entry that gives a Tibetan term should say which system it is using rather than leaving the reader to guess from the shape of the letters.
