Abstract

While the Voynich Manuscript was almost certainly written left-to-right (LTR), the question whether the underlying script or cipher reads LTR or right-to-left (RTL) has received little quantitative attention. We introduce a statistical method that leverages n-gram perplexity asymmetry to determine directional bias in character sequences.
