6. How Close?

If computed values do little more than loosely match the Babylonian data, or if the text is replete with "scribal" errors (which may mask incorrectly assigned dates), then the dating of the tablets would be suspect.

When the line of a Diary states ìthe 18th, Venus was balanced 1 cubit 4 fingers below alpha Leonisî, how close to the star does the computed sky place Venus on the inferred date?
