Daniel Strejc [streytz] (Autumn of 1592 - probably 1669) was a Czech priest of the Unity of the Brethren. He is known for the travelogue Islandia, about the journey to Iceland in 1613, first published in 1638. Strejc was also known under surnames Vetter or Vetterus. Strejc-Vetterus was considered the next senior (the highest religious official within the Unity of the Brethren), succeeding Commenius but being too old he was only named consenior in 1663. The last mention about Strejc comes from a letter written by Commenius in 1669.
