Modern English
Modern English (sometimes New English or NE as opposed to Middle English and Old English) is the form of the English language spoken since the Great Vowel Shift in England, which began in the late 14th century and was completed in roughly 1550.
Glyph
The word "hieroglyph" (Greek for sacred writing) has a longer history in English, dating from an early use in an English to Italian dictionary published by John Florio in 1598, referencing the complex and mysterious characters of the Egyptian alphabet.
The word "glyph" first came to widespread European attention with the engravings and lithographs from Frederick Catherwood's drawings of undeciphered glyphs of the Maya civilization in the early 1840s.
