6.3.11

vapreṣūpalayantrāṇi balavanti mahānti ca
āgataṃ parasainyaṃ tais tatra pratinivāryate

'Vast is the city, gay and strong,
Where elephants unnumbered throng,
And countless hosts of Rákshas breed
Stand ready by the car and steed,
Four massive gates, securely barred,
All entrance to the city guard,
With murderous engines fixt to throw
Bolt, arrow, rock to check the foe,
