August 3

Know thou… that the people aforetime have produced things which the contemporary men of knowledge have been unable to produce. We recall unto thee Murtús who was one of the learned. He invented an apparatus which transmitted sound over a distance of sixty miles. Others besides him have also discovered things which no one in this age hath beheld. Verily thy Lord revealeth in every epoch whatsoever He pleaseth as a token of wisdom on His part. He is in truth the supreme Ordainer, the All-Wise. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)
