Spyridon Marinatos (1901–1974) was a Greek archaeologist who specialised in the Minoan and Mycenaean civilizations of the Aegean Bronze Age, and excavated the Minoan site of Akrotiri (fresco pictured) on Thera between 1967 and 1974. He received several honours in Greece and abroad, and was considered one of the most important Greek archaeologists of his day. He joined the Greek Archaeological Service in 1919 and spent much of his early career on the island of Crete, where he excavated several Minoan sites. He served three times as head of the Greek Archaeological Service, including under the military junta which ruled Greece between 1967 and 1974. He was an enthusiastic supporter of the junta; in the late 1930s, he had been close to the dictatorial regime of Ioannis Metaxas. Marinatos died while excavating at Akrotiri in 1974, and is buried at the site. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
