Vitrelinus Alexander was Pastor of Pinczow in the year 1555. He is often mentioned in the Synodical Acts ; but little is known of his personal history, beyond the meagre account, which Sandius has furnished of him. (B. A. p. 46.) While he was at Pinczow, Nicholas Olesnicki was his patron. He afterwards became Pastor of the Church at Wengrow, in Podlachia, which was under the patronage of John Kiszka, President General of Samogitia.

The following is a list of the writings of Vitrelinus.

1. The Judgment of the Polish Churches in the Cause of Francis Davidis, concerning the Invocation of the Man Christ Jesus, Son of the living God ; transmitted to George Blandrata and the other Brethren in Transylvania. Written at the Synod held at Belzyce, Aug. 24th, 1579, and signed by Alex. Vitrelinus, in the Name of all the Ministers. Clausenburg, 1579.

2. On Baptism, against Faust Socin. MS.

3. A Letter to Christian Francken against his Opinion concerning the Non-invocation of Jesus Christ, the Son of God ; written in the Name of the Synod of Wengrow, May, 1584. MS.

4. An Explanation of the first Chapter of John's Gospel. A.D. 1584. This work, if first written in Polish, as Sandius supposes, was translated into Latin, and published in 4to. at Losk, in Lithuania, A.D. 1586. But Bock thinks that it was written originally in Latin. Daniel Clementinus, who quotes from it, says, that by "the beginning" Vitrelinus understood, the commencement of the human nature of Jesus Christ in the womb of Mary.

5. On the Sin against the Holy Ghost. This work, which is extremely rare, was unknown to Sandius ; but is mentioned by Dan. Salthenius, in his " Bibl. Librorum Rarior."

6. Possibly, too, Vitrelinus was the author of another work, of which no copy is now known to exist, but of which Salthenius gives the title, in the following words. "Veritas, non Persona: seu Consensus Evangelicus et Apostolicus in his, quae sunt Ccena Domini."
