The symbolism here isn't exactly subtle, but here goes anyway. I did go pretty well off from the traditional design on this one. The white horse symbolizes strength and power, inevitably washing over all things. White is the symbol of its pure motives. The five-petaled rose overhead is likewise a symbol of purity and immortality. Five is also considered the number of change. The wheat in the background represents life — we are alike in death, and we will be taken in our time, as the scythe Death wields reminds us, but we grow and are alive now. The hourglass is, naturally, a symbol of time, unstoppable in its flow. And that is good. The flow of time brings not only death and sorrow, but also birth, change, growth, and joy.
