The month of May is dedicated by the ancient world to the Roman goddess Flora, considered a minor goddess to symbolize spring and new life. To the Roman Catholics, May is dedicated to Mary, the mother of Jesus Christ, where children gather and offer flowers to her altar at Catholic Churches.
Jewish communities in the US observe special customs on Shavuot in May. These activities include reading the Book of Ruth or staying up all night to study the Torah (the five books of Moses). Many Jewish people also eat dairy foods during Shavuot. Many homes are decorated with various plants, including those with flowers.
May is indeed a merry month, when her flowers bloom, one cannot help but marvel at their beauty.
