The rope has been sometimes called \*pātinī\* ("that which is laid out") because measurements are made by laying (\*pāta\*) it out on the ground. - [Previous: c10.54](https://indike.org/pramana/ins.science.datta-1932.c10.54) - [Next: c10.56](https://indike.org/pramana/ins.science.datta-1932.c10.56) - [Up: c10](https://indike.org/pramana/ins.science.datta-1932.c10) ## Linked texts (3) - [Mānavaśulbasūtra](https://indike.org/pramana/in.vedanga.kalpa.sulba.manava) — Sanskrit - [Āpastambaśulbasūtra](https://indike.org/pramana/in.vedanga.kalpa.sulba.apastamba) — Āpastamba, Sanskrit - [Kātyāyanaśulbasūtra](https://indike.org/pramana/in.vedanga.kalpa.sulba.katyayana) — Kātyāyana (Vājasaneyi sūtrakāra), Sanskrit --- Source: [https://indike.org/pramana/ins.science.datta-1932.c10.55](https://indike.org/pramana/ins.science.datta-1932.c10.55) · Pramāṇa
