Eta Symbol

The eta symbol is the seventh letter of the greek alphabet. Eta evolved from the Phoenician letter "heth." In ancient times, it represented a consonant sound before becoming a vowel. The uppercase form looks like our "H," while the lowercase resembles a lowercase "n." Eta was sometimes used to represent the number 8 in Greek numerals.
