Here is a beautiful statue of Venus, the goddess of love. It resides at the British Museum in London and it caught my eye because it just seemed too perfect to be ancient.
The statue was discovered by an artist, Gavin Hamilton in 1775 in Ostia near Rome. The description says that at that time, buyers of ancient statues preferred them to be in tact so missing parts were carved by artists and added. On this statue, the arms were restored.
16th century artists performed a little surgical correction on a 1st century piece of art. Fascinating.
