Mycenae's most dramatic discoveries were made by the German archeologist Heinrich Schlieman in 1874-76. The Greek Archeological Society of the time, among other learned academicians in England, Germany and France, thought he was a crazy, rich amateur. Boy did he prove them to be the pendant ic, stuffed shirts that they were. He also discovered Troy.
Schlieman is considered to be the father of modern archeology and as a child was fascinated by Homer.
He was self educated, made a few million supplying the British with supplies during the Crimean war and used it to pursue his hobby: archeology.
He married a Greek girl, Sophia, who was a huge help to him as well! If you want to read a good book about Schlieman try The Greek Treasure by Irving Stone.
Towards the end of the Turkish occupation of Greece, around the end of the 18th and beginning of the 19th Centuries the site became an object of note by a number of early travelers.
It became the object of pilfering by art collectors and purveyors such as English Lord Elgin and Veli, The Pashsa of Naufplion and others.
The bulk of the known treasures of Mycenae were discovered by Schlieman in Grave Circle A, within the citadel itself, and are on display in the National Archeology Museum in Athens.
Grave circles were reserved for the nobility and often had several occupants.
