Symbol (which would appear as Σψμβολ if the name of the font is written in the font itself) is one of the four standard fonts available on all PostScript-based printers, starting with Apple's original LaserWriter (1985). It contains a complete unaccented Greek alphabet (upper and lower case) and a selection of commonly used mathematical symbols. Insofar as it fits into any standard classification, it is a serif font designed in the style of Times New Roman.
Due to its non-standard character set, lack of diacritical characters, and type design inappropriate for continuous text, Symbol cannot easily be used for setting Greek language text, though it has been used for that purpose in the absence of proper Greek fonts. Its primary purpose is to typeset mathematical expressions.
There was also an earlier Symbol designed in 1933 by Carl Albert Fahrenwaldt for Schriftguss Type Foundry. It was a font of decorative initials based on his roman font Minister.[1]
