Karthigai Deepam – Rangoli Designs

Definition

Karthigai Deepam is the Tamil festival of lamps, kept on the full-moon day of the month of Karthigai (November–December) when rows of oil lamps line thresholds, walls, and window ledges — and the kolam beneath them is drawn to carry light: lamp motifs, and real flames set into the design.

History

Karthigai is among the oldest attested Tamil festivals, its lamp observance named in early Tamil literature, and its beacon tradition centred on the Tiruvannamalai hill fire — the great flame lit on the summit as the household lamps are lit below, each register answering the other. The household observance pairs the lamp rows with the threshold kolam in the manner the ethnography documents for the Tamil festival cycle at large: the design drawn first, the lamps placed on and around it as dusk falls.

Description

The evening is the festival’s stage: kolams drawn at dusk rather than dawn, oil lamps placed at the design’s points and borders, and the diya motif drawn between the real flames it mirrors. Designs favour radial layouts that seat lamps symmetrically — the drawing planned as a lampstand in two dimensions, its geometry chosen for the flames it will hold. Households extend the rows over the festival’s days, and the streets after dark carry the tradition’s most luminous displays of the year.

Cultural Context

The festival’s lamps are commonly framed as continuity of household light — flames kept alive and multiplied, carried from the hill’s single beacon to every windowsill — and the kolam beneath them as the prepared ground that receives the observance. Falling weeks after Diwali, Karthigai is often described in Tamil practice as the deeper, older lamp festival of the two; the framing is attributed, and the two festivals’ pairing of flame and drawing is in any case the same gesture twice.

Regional Variations

Karthigai Deepam is Tamil; its lamp-and-drawing pairing parallels Diwali’s across the rest of the country, and the month itself opens the run-up to Margazhi, when the kolam season proper begins. Temple towns keep the festival at greatest scale — Tiruvannamalai’s flame above all — while household practice carries the same observance at threshold size.

The lamp motif is Diya and the standing lamp Lampstand; lamp-seating layouts are described in Radial Structure; the pan-Indian lamp festival is Diwali.
