Creative Brief

Named for the patron saint of librarians and scholars, Jerome draws from the round spectacles depicted in Renaissance portraits of learned men (Ghirlandaio’s Saint Jerome in His Study, Van Eyck’s Virgin and Child with Canon van der Paele). The goal here was not historical reproduction, but a modern frame that carries a quiet authority; something a contemporary scholar might wear that still echoes the old scriptorium.
Design Brief
An off-round lens shape with an extra large keyhole bridge opening, designed to rest on strut pads located more inferior than usual, closer to the geometric center. The endpieces are designed to accommodate an 11mm wide temple, which provides some visual weight at the temples, but is best utilized with rivet hinges, which will break up the visual mass of the endpiece when viewed anterior.
This specific model was designed for use with the TH-43 hinge from ZoyeGlassesParts, and a standard 6mm acetate blank with 4mm pad build-up as defined in the archive. The pad is supplied without splay, since the creator utilizes post-machining processing and hand finishing to achieve the desired result. The specific temple designed for this frame is a Pseudo-Library Temple, 11mm Endpiece.
