Hera is a font family in three weights. The family explores the motion and fluidity of the ball serif, in an evolution from its previous identity as a counterpart to the slab serif. The best of the classic slab fonts ingeniously used the ball serif as a means to terminate a stroke with rotational velocity. In this type universe the slab behaves like physics; the stroke hits the baseline and the impact pancakes it into the slab. As such, a stroke with rotational velocity such as the arm of the lowercase “r” terminates into a vortex, as if the ball serif were the roll to which the ribbon of the stroke was spooled onto. In Hera, there is far less slab, as the slab represents a physical byproduct of right angles and geometric form. Hera is informed by classical slab fonts like Clarendon, the wood type of Vincent Figgins and the work of Herb Lubalin.
