This typeface uses a heavy, blackletter construction with sharply broken curves and faceted terminals that read as chiseled and calligraphic. Stems are thick and dominant, with compact internal counters and pronounced, angular joins that create a rhythmic pattern of verticals. Uppercase forms are tall and assertive, with wedge-like serifs and occasional spur details that add texture without becoming overly ornate. Lowercase maintains the same fractured logic, with narrow apertures, pointed shoulders, and diamond-like dots on i/j that reinforce the gothic texture. Numerals are similarly blocky and segmented, matching the overall stroke grammar and dense color on the page.
Best suited for display applications such as posters, mastheads, title treatments, logos, and packaging where a historic or gothic atmosphere is desired. It can also work for short pull quotes or section headers, but the dense texture suggests avoiding long passages at small sizes.
The overall tone is traditional and ceremonial, evoking manuscripts, heraldry, and old-world signage. Its strong dark color and angular cuts give it a stern, authoritative voice that feels formal and historic rather than casual or contemporary.
The design appears intended to deliver a classic blackletter voice with strong page color and disciplined, angular construction. It prioritizes iconic medieval character and decorative authority while keeping forms consistent enough for punchy, readable display setting.
In running text the repeated vertical rhythm produces a tight, patterned “woven” texture typical of blackletter, with letterforms staying legible best at larger sizes. Sharp corners and compressed counters increase visual intensity, while consistent stroke endings help maintain a cohesive, uniform presence across caps, lowercase, and figures.
