CONT

D'origine arabe, l'arbalète de Jacob fut, avec l'anneau astronomique, un des premiers instruments inventés pour déterminer la latitude et faire le point en mer. Elle était utilisée à la fin de XVème siècle et pendant les grandes découvertes et ne fut abandonnée qu'au XVIIIème siècle. Perfectionnée par l'adjonction de viseurs et d'arcs gradués, elle a conduit au quartier de Davis d'où dérivent l'octant et le sextant.
