when Gutenberg typeset his Bible, he used types of various widhts in
order to achive right-justification. they were of the same height, but
their widths varied, so that when he set a line, he experimented with
types of various widths until the line had the right lengths.
Perhaps he was influenced by the ancient practice in Hebrew calligraphy.
Certain letters on a line were drawn in widened form in order to achieve
justification. This practice carried over into the era of metal typesetting and was
still in use into the 20th Century for prayer books and other religious and
liturgical material, particular when handset type was being used.
