It is considered to be the only native Greek variety of cat.

Aspronisi is an uninhabited island lying within the Santorini caldera. The island was originally formed by the massive Minoan eruption in the 2nd millennium BC, after which it was gradually built up by successive volcanic activity.

The group is located about 10 miles southwest of Santorini and is made up of the islands Christiani, Eschati (Εσχάτη) and Askania (Ασκανιά). The island's area is about 2.35 km². All three islands are now uninhabited but on Christiani there are remains of human settlement dating back to Neolithic times. Christiana islands have been uninhabited since the 1890s and have remained un-farmed since then. As a result, artificial pesticides and fertilizers are absent from this ecosystem. In the mid 1970s, the largest island, Christiani, was considered by NATO as a military base intended to host a missile silo, but this never came to pass. These islands are privately owned and public access is restricted.

Dwarf elephants are prehistoric members of the order Proboscidea which, through the process of allopatric speciation on islands, evolved much smaller body sizes in comparison with their immediate ancestors. Dwarf elephants are an example of insular dwarfism, the phenomenon whereby large terrestrial vertebrates that colonize islands evolve dwarf forms, a phenomenon attributed to adaptation to resource-poor environments and selection for early maturation and reproduction. Some modern populations of Asian elephants have also undergone size reduction on islands to a lesser degree, resulting in populations of pygmy elephants.

Eschati (Εσχάτη) is a Greek island in the Cyclades.

The Grotta-Pelos culture refers to a "cultural" dating system used for part of the early Bronze Age in Greece. Specifically, it is the period that marks the beginning of the so-called Cycladic culture and spans the Neolithic period in the late 4th millennium BC, continuing in the Bronze Age to about 2700 BC. The term was coined by Colin Renfrew, who named it after the sites of Grotta and Pelos on the Cycladic islands of Naxos and Milos, respectively. Other archaeologists prefer a "chronological" dating system and refer to this period as the Early Cycladic I (ECI).

It owes its special peppery and spicy taste to rapid and extensive lipolysis and proteolysis caused by abundant microbial growth encouraged by repeated kneadings performed during the ripening process.

Phylakopi, located at the northern coast of the island of Milos, is one of the most important Bronze Age settlements in the Aegean and especially in the Cyclades. The importance of Phylakopi is in its continuity throughout the Bronze Age and because of this, it is the type-site for the investigation of several chronological periods of the Aegean Bronze Age.

The Phylakopi I culture refers to a "cultural" dating system used for the Cycladic culture that flourished during the early Bronze Age in Greece. It spans the period ca. 2300-2000 BC and was named by Colin Renfrew, after the settlement of Phylakopi on the Cycladic island of Milos. Other archaeologists describe this period as the Early Cycladic III (ECIII).

In the sixth year of the Peloponnesian War (426 BCE), the Athenians purified Delos. They removed all the tombs from that island, and declared it to be unlawful henceforth for any living being to be born or die within it, and that every pregnant woman should be carried over to the island of Rheneia in order to be delivered.
