She is a rare example of a married laywoman who achieved sanctity through her daily life and she is venerated as a saint in the Eastern Orthodox Church, her feast day being on 3 January.
Based on the dates provided in one of her vitas, it seems that Thomais was born at some point between the years 909 and 913 on the isle of Lesbos, though some doubts remain.
[4] Her body was interred in the monastery of Theotokos ta Mikra Romaiou where also her mother, who had entered the convent after the death of Thomais' father, had been a nun and buried.
[6] Thomas' disastrous marriage is contrasted with the happy one of her parents, who are described as "a golden team", and her persistence in doing good works becomes heroic.
[8] However, there is some evidence that her cult became more popular in the late Byzantine period and Russian pilgrims to Constantinople in the fourteenth and fifteenth century describe visiting her tomb in the Theotokos ta Mikra Romaiou monastery.
