Oderic of Portenau, a travelling friar, who died in 1331, mentions Tibet, and is the first who speaks of the Grand Lama as the _pope of the idolaters_. The Romish missionaries of later times made repeated attempts to establish themselves in the Trans-Himalayan regions. The first who appears to have succeeded in penetrating them was Antonio d'Andrada, a Portuguese Jesuit, with three companions of his order. In 1624 they ascended the Ganges by Hurdwar and Srinuggur to Budrinath, a celebrated place of Hindoo pilgrimage on the eastern branch of the sacred river. Apprehending hindrances to their advance, they made a desperate attempt to cross the pass into Tibet, (probably the Niti, or one of those nearer Lake Manusaráwur,) whilst it was still deep in snow, and without a guide. They succeeded, after frightful suffering, in surmounting the pass, but, finding the country at their feet a trackless sheet of snow, were compelled to return. Waiting for the usual convoy after the melting of the winter snow, they again effected the passage, and proceeded to what they call Rudac, the capital of Tibet. There is a fort so called (Radokh or Rohtuk) beyond the Indus, near the head of the Pangkung Lake; but Ladakh or Le is more likely to have been the place intended. Though it seems scarcely credible that four strangers should have found their way twice across the Himalayan passes unguided, and before the regular season of transit, and yet survive to tell the tale, it must be said that Andrada's description of their Himalayan travels, in other respects, bears every mark of truth. The precipitous paths along the Ganges, the files of pilgrims shouting as they trudged to Budrinath, the demon-like Jogees whom they encountered, the straight and lofty pines and cypresses, the large rose-bushes, and forests of flowering trees, (rhododendron,) the rope bridges, the sufferings in the snow and from the attenuated air, are all plainly drawn from actual experience.
