We present an axiom system for plane hyperbolic geometry in a language with lines as the only individual variables and the binary relation of line-perpendicularity as the only primitive notion. It was made possible by results obtained by K. List [6] and H. L. Skala [15]. A similar axiomatization is possible for n-dimensional hyperbolic geometry with n ≧ 4. We also point out that plane hyperbolic geometry admits a ∀∃-axiomatization in terms of line-perpendicularity alone, an axiomatization we could not find.
