[Helleri]

I think that bit at the bottom is meant to be a comically enlarged penis (disguised as part of the acanthus work). The character does seems to have a jovial or mischievous expression. I wonder if this would qualify as a small grotesque? Perhaps a wall plaque?

As for estimated a time and place of creation. Best bet would probably be to go by the clothing of the figure. He's wearing what appears to be a loose garment. Perhaps a one piece tunic type shirt. With a round neck hole that has no split. But a series of buttons running up the forearm.

That's fairly distinctive. Whoever carved it took the time to put in those details. Spend enough time browsing medieval European clothing collections on pintrest and you might find a time and place for which such a men's garment shows prevalence.
