 Marceli Kosman, a modern Polish historian, called Lizdeika the last Kriwe.Vladimir Toporov argued that the Crooked Castle ("castrum curvum") in Vilnius was really Kriwe Castle.The word may be derived from the Baltic root "ram-/rām-", meaning 'calm, serene, quiet', stemming from the Proto-Indo-European "*(e)remǝ-".
