Query: Isomeric Lepton Mass Matrices and Bi-large Neutrino Mixing   We show that there exist six parallel textures of the charged lepton and
neutrino mass matrices with six vanishing entries, whose phenomenological
consequences are exactly the same. These {\it isomeric} lepton mass matrices
are compatible with current experimental data at the $3\sigma$ level. If the
seesaw mechanism and the Fukugita-Tanimoto-Yanagida hypothesis are taken into
account, it will be possible to fit the experimental data at or below the
$2\sigma$ level. In particular, the maximal atmospheric neutrino mixing can be
reconciled with a strong neutrino mass hierarchy in the seesaw case.
