Postnik Yakovlev
16th century Russian architect

Postnik Yakovlev (Russian: Постник Яковлев; born 16th century in Pskov) was a Russian architect best known as one of the builders of the Saint Basil's Cathedral on Red Square in Moscow (built between 1555 and 1560, the other architect is Barma). It is thought that he was nicknamed "Barma" (Барма) ("the mumbler"), although it might be that his full name was, in fact, Ivan Yakovlevich Barma; (Postnik means "Faster", a term used for several religious figures, including Patriarch John IV of Constantinople); Barma might also be Yakovlev's assistant.
According to legend, Ivan the Terrible blinded Yakovlev so that he could never build anything so beautiful again. However, this is probably a myth, as Yakovlev, in cooperation with another master, Ivan Shirjay, designed the walls of the Kazan Kremlin and the Cathedral of the Annunciation in Kazan in 1561 and 1562, just after the completion of St. Basil's. He also designed the northeast chapel of St. Basil's (where Basil himself, the popular Basil Fool for Christ – Yurodivy Vassily Blazhenny – is buried), in 1588, four years after Ivan's death.
According to several historians, Yakovlev also designed churches in Staritsa, Murom, Sviazhsk, and perhaps Vladimir, although others contend that this was another architect with a similar name.

Why this record matters
“Postnik Yakovlev” is worth following because a concise public description often conceals a longer documentary argument. Here, Postnik, Yakovlev and 16th provides the most credible route into that argument.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated May 28, 2026. The linked authority identifier is Q2106252. VIAF identifies the subject as 96420954. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1555, 1560, 1561 and 1562.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
