The Bible Christian argues the reference to windows in Ether 2 is anachronistic.
"Mormonism," The Bible Christian 2, no. 4 (May 1840): 113
The Book forms a very extraordinary supplement to the Bible. In particular, it tells of one Jared who fled from Babel shortly after the flood, to America, "an island of the sea," in decked vessels, in which he was commanded to insert no glass windows;—"for behold they will be dashed in pieces:"—a command which Jared doubtless obeyed; seeing that window-glass was not invented till many centuries afterwards.
