aleph

Around 1800 BCE, Semitic workers in the turquoise mines of the Sinai Peninsula scratched a simple image onto limestone: the head of an ox, tilted on its side. This mark stood for a glottal stop, the catch in the throat before a vowel that English has no dedicated letter to represent. They called it 'alp, the word for ox in their language. The image was the name, and the name was the sound.

By 1050 BCE, Phoenician traders had refined the mark into a sharp, angular character they carried westward across the Mediterranean. When Greek merchants encountered Phoenician script around 800 BCE, they borrowed the letter wholesale, renaming it alpha. Greek had no glottal stop, so alpha became a pure vowel carrier. The word alphabet is just alpha and beta side by side: the ox and the house, standing at the gate of every Western writing system.

Hebrew preserved the ox letter as the first in its own alphabet, a position it has held without interruption since the Second Temple period. In the Zohar, the kabbalistic masterwork compiled in thirteenth-century Spain, aleph is the silent letter, the breath before speech, the unity that contains all duality. Rabbi Akiva in the second century CE taught that each Hebrew letter contained worlds; aleph, being first, contained all of them.

English adopted aleph directly from Hebrew, using it as the name of the letter itself in discussions of Hebrew script or the ancient Semitic alphabets. Jorge Luis Borges chose it in 1945 as the title for his short story about a point in space containing all other points simultaneously. The choice was exact: the first letter, the number one, the shape that started everything.
