## Abstract In this article we study congruences of lines in โ„™^__n__^, and in particular of order one. After giving general results, we obtain a complete classification in the case of โ„™^4^ in which the fundamental surface __F__ is in fact a variety, i.e. it is integral, and the congruence is the ir
