This typeface is a slanted serif with sturdy, squared-off slab serifs and gently bracketed joins. Strokes are broadly even with only mild modulation, giving it a steady texture, while the italic construction introduces a clear diagonal rhythm and subtle calligraphic stress. Proportions feel moderately open with a normal x-height and compact ascenders/descenders, supporting readable word shapes. The serifs are assertive but not heavy-handed, and many joins and terminals are clean and slightly chamfered, keeping the overall color crisp in text.
It suits long-form reading contexts such as books, magazines, and essays, where the steady stroke weight and clear italic rhythm maintain an even texture. The slanted, slab-serif voice also works well for pull quotes, captions, and emphasized passages that need distinction without becoming overly ornamental. Oldstyle-style numerals make it especially comfortable for text with frequent inline figures.
The tone is bookish and editorial, pairing a traditional italic voice with a sturdier, workmanlike slab presence. It reads as confident and somewhat formal, with a classical, print-oriented character rather than a casual or decorative one.
The design appears intended to provide an italic companion with robust, square-ended slab serifs that stays composed in continuous text. Its restrained contrast and disciplined spacing suggest a focus on dependable readability and a classic editorial palette, while keeping a distinctive slab-backed personality.
The lowercase shows a single-storey “g” and a single-storey “a,” reinforcing an italic, handwritten logic. Numerals appear oldstyle (with varied heights and descenders), which adds a literary, text-centric feel and helps the figures blend smoothly into running copy.
