Varick Street runs north-south primarily in the Hudson Square district of Lower Manhattan in New York City.
 Varick Street's northern terminus is in the West Village, where it is a continuation of Seventh Avenue South south of Clarkson Street.
 It continues downtown through Hudson Square and TriBeCa until it reaches Leonard Street, where it merges with West Broadway.
 Motor traffic is one-way southbound.
 Major east-west streets crossed include Houston Street and Canal Street.
 Approaching Broome Street, the two rightmost lanes of Varick Street are reserved for traffic entering the Holland Tunnel, where backups often occur at rush hour.
"The Lamentable and Tragical History of Titus Andronicus," also called "Titus Andronicus' Complaint," is a ballad from the 17th century about the fictional Roman general, Titus, and his revenge cycle with the Queen of the Goths.
 Events in the ballad take place near the end of the Roman Empire, and the narrative of the ballad parallels the plot of William Shakespeare's play "Titus Andronicus".
 Scholarly debate exists as to which text may have existed first, the ballad or the play (indeed, there is a third potential "Titus Andronicus" source, a prose history published in chapbook form during the 18th century).
 The ballad itself was first entered on the Stationers' Register in 1594, the same year the play was entered.
 Surviving copies of the ballad can be found in the British Library, in the Huntington Library, and at Magdalene College, Cambridge.
 Online copies of the facsimiles are also available for public consumption at sites such as the English Broadside Ballad Archive.
