During the Renaissance, clothing was fastened together in many ways. There were buttons made of fabric, metal, bone, seashells and wood. Clasps were used not only on cloaks but also on doublet, jerkins and bodices.
Eyelets, lacing rings and lacing eyes were other fastener choices during this time period. Although most eyelets were sewn with thread there is evidence of both lacing eyes and metal eyelets used on the same garment in Carlos Crivelli's Mary Magdelene painting. Leonardo da Vinci's Ginerva di' Benci (detail pictured on left) is one of the clearest examples of lacing rings used on a bodice.
