It has been suggested that the crossroads was sacred to Hekate due to her having been abandoned at a crossroads as a baby by her mother Pheraea, and then rescued and brought up by shepherds. This Thessalian tale comes from a scholiast to Lycophron's 3rd century BCE play Alexandria, and was a late invention.
Aristophanes recorded that offerings to Hekate were made "on the eve of the new moon" which is when the first sliver of the new moon is visible, signifying a possible connection with Hekate as a lunar goddess, rising, like the moon, from the underworld on the night of the new moon.
There are also references to the offerings being made on the thirtieth day of the month, but keep in mind that this was calculated on the Greek calendars, it would vary from state to state as there was no uniformity in the calendar system being used.
It has further been suggested that the offerings made at the Hekate Suppers were a form of charity, and certainly the consumption of the food by the poor was noted by Aristophanes (5th century satirist):
The 10th century Byzantine encyclopedia, the Suda, paraphrased this quote and added the following:
Various sources mention different foods offered to Hekate at the suppers. These were:
- Magides - A type of loaf or cake
- Mainis - Sprat
- Skoroda - Garlic
- Tigle - Mullet
- Psammeta - Sacrificial cake somewhat like the psaista
- Oon - Eggs (raw)
- Tyros - Cheese
- Basunias - A type of cake
