Final answer:
Geoffrey Chaucer wrote about the tradition of Valentine's Day, linking it to romantic love in his poem 'The Parliament of Fowls'. The holiday's association with a Christian martyr and the inclusion of Western culture has led to a ban in some countries, like Iran in 2011.
Step-by-step explanation:
One author who explored the tradition of Valentine's Day in his works is Geoffrey Chaucer, often credited with popularizing the holiday with his poem 'The Parliament of Fowls'. In this poem, Chaucer links the romantic traditions associated with Valentine's Day to the mating of birds, which he suggests, occurs on February 14th. While Valentine's Day is indeed named after a Christian martyr, Saint Valentine, the traditions of the day as we know them now, including expressions of love and the exchange of gifts, have been shaped by various authors and societal customs over the centuries.
It is important to note that the modern celebration of Valentine's Day contains elements that may not necessarily align with all cultural or religious beliefs, which can sometimes lead to resistance or adjustments in different countries. For instance, the government of Iran banned activities associated with Valentine's Day on February 13, 2011, citing its origin from a Christian tradition and the need to prevent the spread of Western culture.
