"The upper part, known as the Case, may be regarded as the great Heidelburgh Tun of the Sperm Whale."

The Heidelberg Tun is an extremely large wine vat contained within the cellars of Heidelberg Castle in south-western Germany. There have been four such barrels in the history of Heidelberg; the present one has a capacity of approximately 220,000 litres (58,100 U.S. gallons) and was made in 1751. One hundred and thirty oak trees were reputedly used in its construction.
