This ostrich egg on a wooden base is a reference to the cabinets of curiosity that emerged from the 16th century onwards. Because of the great voyages of discovery of that time, people came into contact with exotics, such as ostriches and ostrich eggs. Some were put up for display. Some examples were even mounted and modified into cups. A wonderful 16th century example can be found in the British museum.
This candle holder is a reference to the bossed beaker. These are glass beakers that occur in late 16th-century or 17th-century archaeological contexts. The wall of the bossed beaker is decorated with a relief pattern in the form of drops, tears, diamonds, warts or … bosses. Just like with this candle holder.
