Q1. In which country do the majority of surviving Ogham inscriptions appear?
  • A. Scotland
  • B. Ireland ✓
  • C. Wales
  • D. Cornwall

Why: Ireland holds the largest number of surviving Ogham inscriptions, roughly 360 of the approximately 400 known examples, most of them carved on standing stones and boulders.

Q2. What is the basic structure of the Ogham alphabet?
  • A. A series of pictographs representing objects
  • B. A set of strokes cut along a vertical or diagonal line, grouped into families ✓
  • C. A syllabary with a separate symbol for every vowel-consonant pair
  • D. A system of knots tied in cords

Why: Ogham characters are composed of straight strokes (notches and lines) arranged along a central stemline, and the letters are organised into groups of five, called aicme, based on the number of strokes.

Q3. Which language is most Ogham inscriptions written in?
  • A. Latin
  • B. Old Norse
  • C. Early Irish (Primitive or Old Irish) ✓
  • D. Welsh

Why: Most Ogham inscriptions record names in an early form of the Irish language, and this link to Irish is central to understanding the script's origins and use.

Q4. Approximately when was the Ogham script most likely developed?
  • A. Around the 1st century BCE
  • B. Around the 4th to 5th century CE ✓
  • C. Around the 10th century CE
  • D. Around the 15th century CE

Why: Ogham is generally dated to the 4th or 5th century CE, with its use continuing into the 6th and 7th centuries, and it was likely inspired by Latin alphabetic writing.

Q5. What is the traditional Irish name for the Ogham script's earliest-used direction of reading?
  • A. It was read from right to left like Hebrew
  • B. It was read from bottom to top along the stemline ✓
  • C. It was read in a spiral from the centre outward
  • D. It was read from top to bottom in columns

Why: Ogham inscriptions are typically read from bottom to top, with the stemline serving as the reference axis for the strokes, which is a distinctive feature of the script.

Q1. How many basic consonant characters are in the core Ogham alphabet?
  • A. 12
  • B. 15 ✓
  • C. 20
  • D. 26

Why: The core Ogham alphabet contains 20 characters in total, arranged into 4 aicme (groups) of 5 letters each, but the basic consonant and vowel characters together make up 20 with the vowels counted among them, so the commonly cited total of 20 is the key figure.

Q2. How are the letters of the Ogham alphabet traditionally grouped?
  • A. By alphabetical order
  • B. Into 4 groups called aicme, each containing 5 letters ✓
  • C. Into 2 groups of 10 letters
  • D. By the length of each letter's strokes

Why: Ogham letters are organized into four groups called aicme (singular aicme, often anglicized as 'aicme'), each containing five letters, which reflects the structure found in medieval Irish manuscripts.

Q3. Which Ogham letter group contains the vowels?
  • A. Aicme Beithe
  • B. Aicme Hamhna
  • C. Aicme Muine
  • D. Aicme Ailme ✓

Why: Aicme Ailme, the first group, contains the vowels A, O, U, E, and I, which are marked by strokes drawn across or to the left of the stemline.

Q4. How is Ogham written and read?
  • A. Left to right, carved in horizontal lines
  • B. Top to bottom in a single column
  • C. Along the edge of a stone, with the stemline as a central reference ✓
  • D. In circles spiraling inward

Why: Ogham is typically carved along the corner edge of standing stones, with a central stemline (druim) serving as the reference line, and strokes extending to the left or right of it.

Q5. What is the name of the central line that Ogham strokes are drawn relative to?
  • A. The cord
  • B. The spine or stemline (druim) ✓
  • C. The root
  • D. The baseline

Why: The central line is called the druim (meaning spine or ridge), sometimes rendered as stemline in English. Letter strokes are drawn to its left or right, or across it for certain letters.
