Others such as Gripping Beast, etc. who make Renaissance or later Moslem figures for Spanish Reconquista, Crusades, Ottoman Empire, etc.
Many of these may be too late for prototypical Renaissance era figures but some may work for you. Of course all of these will be much smaller than Redoubt's "monsters."
