POPPY SEEDS
Divination by smoke was very common in many ancient cultures.
For this purpose Poppy seeds were often used on the fire.
If the smoke rose lightly and straight towards the heavens it was considered a good sign.
If however, the smoke hung around it wa considered a bad omen.
In ancient Europe a pregnant woman would place Poppy seeds on a window ledge if she wanted a Boy, and sugar if she wanted a Girl.
