Episode 7 of Yuri on Ice allowed us to experience the paradox known as
Kiss, where the characters simultaneously kissed and didn’t kiss as long as the actual frame of their lips touching was not shown. The result depends entirely on the observer of the event.
The Nemi Ships were two ships, with one ship larger than the other, built by the Roman emperor Caligula in the 1st century AD at Lake Nemi. Although the purpose of the ships is only speculated on, the larger ship was essentially an elaborate floating palace, which contained quantities of marble, mosaic floors, heating and plumbing such as baths among its amenities. Both ships featured technology long thought to be recent inventions. It has been stated that the emperor was influenced by the lavish lifestyles of the Hellenistic rulers of Syracuse and Ptolemaic Egypt.
There is considerable speculation regarding why the emperor Caligula chose to build two large ships on such a small lake. From the size of the ships it was long held that they were pleasure barges, though, as the lake was sacred, no ship could sail on it under Roman law implying a religious exemption.
