It is amusing and ironical that a proverb said so long ago is immensely significant today as well. The origin to the proverb “Home is where the heart is” is given by Roman naval commander and naturalist, Pliny the Elder. He was formerly known as Gaius Plinius Secundus.
Naval must have had a keen idea that what and where the home is. Undoubtedly the concept lies in returning to the place where you belonged or have spent the most cherished time of your life.
