Decorative fonts (also called Ornamentals) have been around since the 1800s. They are often used for titles, headings, and other display purposes. They are notoriously tiring to read in any large quantity. Ironically, the World Wide Web and the proliferation of digital type tools have made decorative fonts some of the most commonly developed fonts today.
