Mathematical Symbols

Some mathematical symbols are similar to letters of the alphabet, but are not exact representations.  For example, the existential quantifier is represented as a backwards capital E, and the universal quantifier is an upside-down capital A.  Can anyone help me with the origin of these symbols, and do they have any connection with the letters to which they are similar?
