Let
V be the complex vector space
Cl, \mathscr{A} an arrangement in
V, i.e. a finite family of hyperplanes in
V In [11], Moishezon associated to any algebraic plane curve \mathscr{C} of degree
n a braid monodromy homomorphism θ
Fs→
B(
n), where
Fs is a free group,
B(
n) is the Artin braid group. In this paper, we will determine the braid monodromy for the case when \mathscr{C} is an arrangement \mathscr{A} of complex lines in
C2, using the notion of labyrinth of an arrangement. As a corollary we get the braid monodromy presentation for the fundamental group of the complement to the arrangement.
