Talk:Rola coat of arms

date error
The reference "Długosz, Jan (c. 1464–1480). Insignia seu clenodia Regis et Regni Poloniae." throws a "Check date values in: |date=" error. In trying to determine the correct date, I found this text with the same title. Are they the same reference? The author doesn't seem to be. - Paul2520 (talk) 05:57, 4 January 2016 (UTC)
