Better known than Prokop is Brother Lucas, the foremost representative of the "large party" during its struggle; he is yet more noteworthy as the man who after its victory reorganised the Unity, and, to a certain extent, altered its institutions in a more enlightened and liberal manner. The works of Lucas, all written in Bohemian, are numerous; he is indeed, next to Komenský, the most voluminous writer of the Unity. Lucas, generally known as LUCAS OF PRAGUE, was born about the year 1460. He was greatly impressed by the writings of the early members of the Unity, and, together with his friend the young nobleman Lawrence of Krasonický, he joined the community about the year 1482. He soon attained a prominent position among the brethren, and in 1490 was already a member of the "smaller council." When the differences of the Unity between the "large" and the "small" party arose, Lucas declared himself energetically in favour of the former, and was indeed one of its representatives at several assemblies. The discord among the brethren, and the religious uncertainty which was one of its results, seems to have rendered yet stronger the desire for a return to the primitive Church, which, sometimes more obvious, sometimes scarcely perceptible, can yet be traced in the writings of all Bohemian reformers. Some of the brethren maintained that in distant Eastern lands Christians yet existed who had retained the purity of the primitive Church, both as regards doctrine and the conduct of life. The Unity decided to send out several brethren, who were to discover these communities which entirely conformed with the primitive Church. Lucas, with two companions, started for this purpose for Constantinople, where they separated. Lucas himself appears to have visited Mount Athos and the communities of the Bulgarians, and of the Bohomils in Bosnia. Fertile writer though he was, Lucas has unfortunately left us no account of his travels, for which we could well have spared one or two of his sixty-eight theological works. The first of these works, entitled _The Bark_, was written shortly after his return from his journey. As already mentioned, it involved him in a controversy with Brother Prokop.
