Pausanias Description of Greece 2.18.1

[1]
  By the side of the road from Mycenae to Argos there is on the left hand a hero-shrine of Perseus. The neighboring folk, then, pay him honors here, but the greatest honors are paid to him in Seriphus and among the Athenians, who have a precinct sacred to Perseus and an altar of Dictys and Clymene, who are called the saviours of Perseus. Advancing a little way in the Argive territory from this hero-shrine one sees on the right the grave of Thyestes. On it is a stone ram, because Thyestes obtained the golden lamb after debauching his brother's wife. But Atreus was not restrained by prudence from retaliating, but contrived the slaughter of the children of Thyestes and the banquet of which the poets tell us.

[1] By the side of the road from Mycenae to Argos there is on the left hand a hero-shrine [ hērōion] of Perseus. He gets honors [ tīmai], as I discovered, from the local-population-nearby [ proskhōrioi] here as well [as inside the walls of Mycenae], but the greatest honors are paid to him in Seriphos and among the Athenians, who have a precinct [ temenos] sacred to Perseus and an altar [ bōmos] of Dictys and Klymene, who are called the saviors [ sōtēres] of Perseus. As one advancxes in the Argive territory from this hero-shrine [ hērōion], therfe is on the right the tomb [ taphos] of Thyestes. On it is a ram [ krios] made of stone, because Thyestes obtained a golden lamb [ arēn] after seducing his brother’s wife. Atreus was not restrained by prudence [ logismos] from retaliating, but contrived the slaughter of the children of Thyestes and the banquet that is sung about in songs.
