Did a writing system ever develop that had a bi-directional writing style, alternating every line, with character orientation and order being preserved between lines? (Essentially Boustrophedon, without changing the orientation or word order of letters each line)
A hypothetical example of this writing system, would be the following:
"The quick brown fox
".dog lazy the over jumps
(Reading L-R in Ln 1, then R-L in Ln 2)
