For decades, the dominant view among Maya scholars, championed above all by the British epigrapher J. Eric S. Thompson, was that Maya glyphs were essentially symbolic and calendrical, not a script capable of spelling out ordinary words the way an alphabet or syllabary could. In 1952, a Soviet linguist named Yuri Knorozov, working from a sixteenth century Spanish missionary's garbled attempt at a Maya alphabet, argued the opposite: that Maya writing combined logograms with genuine phonetic, syllabic signs, and that the missionary's confused document actually preserved real phonetic values once read correctly. Thompson rejected the idea outright and used his considerable influence in the field to discourage it for years, a resistance later writers have described as personal as much as scientific, sharpened by the Cold War-era discomfort of an American-led field being challenged from Moscow. Thompson held his ground until his death in 1975. Only then did Knorozov's phonetic approach gain wide acceptance, and researchers such as Linda Schele, Floyd Lounsbury and David Stuart built directly on it through the 1970s and 1980s, turning what had been treated as decorative symbolism into a script that could finally be read as connected, historical language.
