A is for Ambigram
"Although accounts of the Illuminati emblem were legendary in modern symbology, no academic had ever actually seen it. Ancient documents described the symbol as an ambigram - ambi meaning 'both' - signifying it was legible both ways. And although ambigrams were common in symbology - swastikas, yin yang, Jewish stars, simple crosses - the idea that a word could be crafted into an ambigram seemed utterly impossible. Modern symbologists had tried for years to forge the word 'Illuminati' into a perfectly symmetrical style, but they had failed miserably. Most academics had now decided the symbol's existence was a myth."
- from Angels and Demons, chapter 9
