This stele of a male with a stick and a sword was found in the Kerameikos cemetery at Athens. The two parts were found in 1935, and in 1937/38. It probably dates to the mid-6th century BC, and is considered to be one of the earliest Attic examples (Richter, no. 23; Knigge, fig. 24). It was associated with a mound on the west side of the Sacred Way. The stele may have been placed over the shaft grave that was found in the mound (Knigge, p. 105 under no. 15).
The stele appears to have had a sphinx mounted at the top.
German excavations in the Kerameikos, in the bed of the river Eridanos, revealed major deposits of pot sherds or ostraka with the incised names of individuals. They include:
Aristeides Lysimachou, candidate in the 480s
Kallias Kratiou, candidate in the 480s
Megakles Hippokratous, candidate in the 480s [or later]
Themistokles Neokleous, candidate in the 480s [or later]
Kimon Miltiadou, candidate in the mid 5th century
Although in some cases the date of the (successful) ostracism is known, the individual could have been a candidate in earlier voting.
These ostraka were used in the process of ostracism in the Athenian democracy to restrict the power of a person who had been seen as becoming too powerful. If sufficient votes were cast against an individual they were forced to go into exile.
Note that some of these ostraka come from the same pot.
